Chapter 15
Effect Rules
15-1Effects
15-1-1An effect refers to the processing activated by a card that affects the game or cards themselves.
15-1-2A single effect is processed in the order shown in the text on the card.
15-1-3A prohibiting effect takes precedence over an enabling effect. (Example: A Digimon with a "[Your Turn] This Digimon can also attack your opponent's unsuspended Digimon" effect can't attack an unsuspended Digimon with an "[Opponent's Turn] This Digimon can't be attacked" effect.)
15-1-4In some cases, multiple processes will be performed in a single effect. Once all of the processes for such an effect have ended, the effect will be resolved.
15-1-5If an effect is mandatory and not optional, its processing must be performed whenever possible.
15-1-6The processing to execute is chosen, then the processing is executed for the effect. Once the processing to execute is chosen, the effect is considered to be activated.
15-1-7If an effect doesn't specify an area, it means that it can specify or reference a card in the battle area, or that it can affect the battle area. (Example: "[On Play] Delete 1 of your opponent's Digimon with <Blocker>" is an effect where you specify 1 of your opponent's Digimon with <Blocker> in the battle area to be deleted.)
15-1-8Effects that specify or reference Security Digimon can specify, reference, or affect Security Digimon.
15-1-9If an effect's trigger conditions or processing conditions include placing a card in an area other than the field, the conditions will be met even if the card isn't actually placed in that area due to Digi-Egg card or token rules.
15-1-10If an effect's trigger conditions or processing conditions include a card being added to an area other than the field, the trigger conditions won't be met by a Digi-Egg or token because the card isn't actually placed in that area due to Digi-Egg card or token rules.
15-2Effect Types
15-2-1Effects are divided into the following types.
15-2-1-1An effect activated by a Digimon card, Digimon, or Security Digimon is considered a Digimon effect.
15-2-1-2An effect activated by a Tamer card or Tamer is considered a Tamer effect.
15-2-1-3An effect activated by an Option card is considered an Option card effect.
15-3Inherited Effects
15-3-1An inherited effect is an effect gained by a Digimon from a digivolution card. This effect can't be activated by just 1 card.
15-3-2An inherited effect gained by a Digimon is considered an effect activated by a Digimon regardless of the digivolution card's card category. Therefore, the effect type for these effects is considered to be Digimon effects.
15-3-3If "this card" is specified in an inherited effect, that inherited effect is considered to be triggered and activated by that card itself that is or was in digivolution cards.
15-4Effect States
15-4-1Activation
15-4-1-1Activation refers to an effect being executed.
15-4-1-2When a card activates an effect, all of the effect is resolved, even if that card becomes a new card during the processing for the activated effect. (Example: If your Digimon has "[When Digivolving] Delete 1 of your opponent's Digimon with 8000 DP or less and return 1 of their level 6 or higher Digimon to the bottom of the deck," when you delete 1 of your opponent's Digimon with 8000 DP or less, you will process "return 1 of their level 6 or higher Digimon to the bottom of the deck," even if another immediate-type effect deletes your Digimon.)
15-4-2Triggering
15-4-2-1Triggering refers to when the conditions have been met for an effect to trigger. Some effects activate without triggering.
15-4-2-2When an effect's trigger conditions are met during a game, it will trigger no matter the circumstances, even when processing is being performed for a rule or effect.
15-4-2-3Effects that are pending activation must be activated 1 at a time. Multiple triggered effects can't be activated at the same time.
15-4-2-4If an already triggered effect's trigger conditions are met again before it activates, that effect will be triggered again.
15-4-3Simultaneous Triggering
15-4-3-1Simultaneous triggering refers to when multiple effects trigger at the same timing.
15-4-3-2If multiple effects are triggered before a single rule or effect is resolved, they all trigger simultaneously. If effects trigger simultaneously, the effects will be pending activation and activate 1 at a time. (For details, refer to 15-4-4 "Pending Activation")
15-4-3-3When an effect is triggered by a rule check, it triggers simultaneously with other effects that triggered at that timing. (Example: An [On Deletion] effect on a Digimon that was deleted by its DP becoming 0 at the start of your turn will trigger simultaneously with [Start of Your Turn] effects.)
15-4-3-4The activation order is determined for effects that trigger simultaneously by choosing the next pending activation effect after each effect has been resolved.
15-4-3-5Effects that trigger simultaneously are processed by performing the following procedure.
15-4-3-5-11 effect is chosen to activate from among the turn player's effects that triggered simultaneously. This step is repeated until there are no more pending activation effects for the turn player.
15-4-3-5-2Once there are no more pending activation effects for the turn player, 1 effect is chosen to activate from among the non-turn player's effects that triggered simultaneously. This step is repeated until there are no more pending activation effects for the non-turn player.
15-4-4Pending Activation
15-4-4-1Pending activation refers to the period until a triggered effect activates.
15-4-4-2Effects that are pending activation must be activated 1 at a time. Multiple triggered effects can't be activated at the same time.
15-4-4-3When a card with an effect that's pending activation becomes a new card before the effect activates, the effect can no longer be activated. (Example: When an [On Play] effect is triggered by a card being played, if the card is removed from the battle area before the effect is activated, the effect can no longer be activated.)
15-4-4-4When a card with an effect that's pending activation loses the effect before it activates, the effect can no longer be activated. (Example: When a Digimon with the text "[When Attacking] <Draw 1>" and "[When Attacking] This Digimon may digivolve into a Digimon card with the [Hybrid] trait in the hand with the digivolution cost reduced by 1" attacks, then it digivolves from the 2nd [When Attacking] effect, the 1st [When Attacking] effect can no longer activate.)
15-4-4-5When a card with an effect that's pending activation 24 no longer meets the trigger conditions of that effect before it activates, the effect can no longer be activated.
15-4-5Derived Triggering
15-4-5-1Derived triggering refers to an effect that newly triggers while simultaneously triggered effects are still resolving. (For details, refer to 15-8-3 "Trigger- Type Effects")
15-4-5-2A derived triggering effect will activate before previously triggered effects that are pending activation.
15-4-5-3If a derived triggering effect occurs for the non-turn player when there are pending activation effects for the turn player, the derived triggering effect will activate first.
15-5Trigger Conditions
15-5-1Trigger conditions are the conditions for an effect to trigger. As soon as the trigger conditions are met, that effect will trigger. Trigger conditions include timings when an effect would trigger such as "when [...] would" text.
15-5-2A triggering from 1 trigger condition is considered to only trigger once, even if it occurred multiple times at the same time. (Example: An effect that reads "[Opponent's Turn] When a card is removed from your security stack, <De- Digivolve 1> 1 of your opponent's Digimon" will only trigger once, even if 2 or more cards are trashed from your security stack at the same time.)
15-5-3If an effect's trigger conditions are met as soon as a card is placed in an area where they can trigger, that effect will trigger. Example: If a card has a "[Your Turn] [Once Per Turn] When your effect places a digivolution card under this Digimon, gain 1 memory" inherited effect, the trigger conditions will be met even when that card itself is placed in digivolution cards by one of your effects.)
15-6Processing Conditions
15-6-1When processing has processing conditions, its text will show the conditions for processing the effect. The processing can be executed when those conditions are met. Processing conditions include text such as "if" or "while". (Example: "While this Digimon is suspended" is 2 a processing condition in an "[All Turns] While this Digimon is suspended, this Digimon gets +3000 DP" effect.)
15-6-2A processing condition is a condition for a process to be performed after text such as "if" or "while." Different processes in the same effect don't have to meet the processing conditions for other processes. (Example: If an effect reads "[On Deletion] If you have 1 or fewer Tamers, you may play 1 [Kiriha Aonuma] from your hand without paying the cost. Then, <Save>," <Save> can be processed even if you have 2 or more Tamers.)
15-6-3An effect can't be activated when none of its processing conditions are met. (Example: An effect that reads "[When Digivolving] If you don't have [Marcus Damon], you may play 1 [Marcus Damon] from your hand without paying the cost" can't be activated when you have [Marcus Damon] in the battle area.)
15-7Optional Processing Conditions
15-7-1If an effect has optional processing conditions, its text will show the conditions for processing the effect. If the player chooses to execute the processing for the conditions and is successful, the processing after the conditions is performed. Optional processing conditions include text such as "by X, Y." (Example: If an effect reads "[On Deletion] By trashing 1 card in the hand, gain 1 memory," The "by trashing 1 card in the hand" part is an optional processing condition.
15-7-2If the content of the optional processing conditions isn't executed, the processing after the conditions can't be executed. (Examples: If an effect reads "[When Digivolving] By trashing 2 cards in your hand, this Digimon unsuspends. Then, if [WereGarurumon] or [X Antibody] is in this Digimon's digivolution cards, you may return 1 Digimon card with [Garurumon] or [X Antibody] in its name from your trash to the hand," unless the player trashes 2 cards in their hand, "this Digimon unsuspends" and the content after "then" can't be executed.)
15-7-3It isn't possible to only perform some of the optional processing conditions. (Example: If an effect reads "[On Deletion] By returning 1 [Kimeramon] and 1 25 [Machinedramon] from your trash to the bottom of the deck, you may play 1 [Millenniummon] from your trash without paying the cost," a player can't just return 1 [Kimeramon] or 1 [Machinedramon] to the bottom of their deck.
15-7-4A player can choose whether or not to execute the content of optional processing conditions, regardless of whether or not the content of the conditions can be executed. (Example: If an effect reads "[When Attacking] By trashing your top security card, 1 of your opponent's Digimon gets -5000 DP for the turn," and the player doesn't have even 1 security card, they can choose to execute the content of the conditions, but if executing them isn't possible, none of the processing after the conditions can be executed.)
15-7-5A player can choose to execute the content of optional processing conditions, regardless of whether or not the content after the conditions can be executed. (Example: If an effect reads "[When Attacking] By trashing your top security card, 1 of your opponent's Digimon gets -5000 DP for the turn," a player can choose to trash their top security card even when the opponent doesn't have any Digimon in the battle area.)
15-8Effect Categories
15-8-1Effect categories include persistent, trigger-type, activation-type, and immediate-type.
15-8-2Persistent Effects
15-8-2-1Persistent effects are constantly activated without being triggered. This refers to effects with text such as "[Your Turn] This Digimon gets +1000 DP" that don't have any particular trigger timings shown.
15-8-2-2Persistent effects are constantly activated as soon as their activation conditions are met. (Examples: If a Tamer card has an effect that reads "[Your Turn] All of your Digimon get +1000 DP," the effect will be constantly activated as soon as your turn begins.)
15-8-2-3Persistent effects won't be activated as soon as their activation conditions are no longer met. (Examples: If a Tamer card has an effect that reads "[Your Turn] All of your Digimon get +1000 DP," the effect will no longer be activated as soon as the opponent's turn 2 begins.)
15-8-2-4When multiple persistent effects are activated, they all overlap.
15-8-2-5If multiple persistent effects with conflicting content are activated, effects that activate afterward take priority, except prohibiting effects.
15-8-2-6Persistent Effects With Processing Conditions
15-8-2-6-1Persistent effects with processing conditions will be constantly activated while their processing conditions are met.
15-8-2-6-2Persistent effects with processing conditions won't be activated as soon as their processing conditions are no longer met.
15-8-3Trigger-Type Effects
15-8-3-1A trigger-type effect will always trigger as soon as its trigger conditions are met, then the effect will activate. If an effect reads "[When Attacking] Lose 2 memory" or "[Your Turn] When effects suspend this Digimon, suspend 1 of your opponent's Digimon," that shows a trigger timing.
15-8-3-2Trigger-type effects can't activate during the processing for a rule or effect.
15-8-3-3A trigger-type effect will trigger when the specific conditions are met for the effect on that card to trigger.
15-8-3-4Trigger-type effects won't trigger when their trigger conditions aren't met.
15-8-3-5If a trigger-type effect triggers when a card is deleted, the card where it will be pending activation is the card that was the top card in the original area. (Example: Upon the deletion of a Digimon with an inherited effect that reads "[On Deletion] Gain 1 memory" on its digivolution card, that effect will trigger, and it will be pending activation for the card that was the top card of that Digimon.)
15-8-3-6If a trigger-type effect triggers at the end of the turn timing, it will trigger as soon as the end of the turn timing arrives. Once an effect triggers, it will remain triggered, even if the memory increases or decreases.
15-8-3-7If an unspecified reference is to be made during the 26 processing for a trigger-type effect, the reference is made in the state when the processing is being performed. (Example: If an effect reads "[All Turns] [Once Per Turn] When a card is added to your security stack, return 1 of your opponent's Digimon with a level less than or equal to the number of your security cards to the hand," if you have 4 security cards when referencing them for the processing, you would return 1 of your opponent's level 4 or lower Digimon to the hand.)
15-8-3-8If a reference in the same state as the effect's trigger conditions is to be made during the processing for a trigger-type effect, the state where the effect has triggered will be referenced. The state where the effect has triggered will be referenced, even if the state changes after the effect triggers. This refers to effects where text such as "when another of your Digimon is played" is a trigger condition and a reference is made using text such as "Digimon with a level less than or equal to the played Digimon." (Example: When an effect plays a level 4 Digimon and an effect reads "[All Turns] When an effect plays another of your Digimon, delete 1 of your opponent's Digimon with a level less than or equal to the played Digimon," this effect deletes 1 of your opponent's level 4 or lower Digimon, even if the Digimon digivolves into a level 5 Digimon before this effect activates.)
15-8-3-9Trigger-Type Effects With Processing Conditions
15-8-3-9-1A trigger-type effect with processing conditions will always trigger as soon as its trigger conditions are met, then the effect will activate if the processing conditions are met.
15-8-3-9-2Trigger-type effects will trigger if their trigger conditions are met, regardless of whether or not their processing conditions are met. However, the processing conditions must be met at the time of activation in order for the effect to activate.
15-8-3-9-3If a reference is to be made in the 2 processing conditions for a trigger-type effect, the reference is made in the state when the processing is being performed. (Example: If an effect reads "[All Turns] When your opponent plays a Digimon, by suspending this Tamer, if that Digimon is level 4 or higher, gain 1 memory. If it is level 3, <Draw 1>," you will gain 1 memory if your opponent's Digimon is level 4 upon being referenced when this effect activates.)
15-8-3-9-4If a reference is to be made in the processing conditions for a trigger-type effect that will trigger when a card is removed from an area, the reference is made in the state when the effect triggered. (Example: If an effect reads "[On Deletion] When this Digimon has digivolution cards, you may play this card from your trash without paying the cost," it references whether or not that Digimon has digivolution cards upon deletion.)
15-8-4Activation-Type Effects
15-8-4-1Activation-type effects are effects that can be optionally activated by a player. These include effects with [Main] text such as "[Main] [Once Per Turn] By paying 2 cost, delete 1 of your opponent's Digimon with DP less than or equal to this Digimon’s DP."
15-8-4-2Activation-type effects can be activated during your main phase by declaring their activation when there is no unresolved processing.
15-8-4-3Activation-Type Effects With Processing Conditions
15-8-4-3-1A player can only declare activation of an activation-type effect while its processing conditions are met.
15-8-4-4Activation-Type Effects With Optional Processing Conditions
15-8-4-4-1If an activation-type effect has optional processing conditions, a player can only 27 declare activation while the optional processing conditions can be performed. In addition, once declared, the optional processing conditions must be performed. (Example: Activation of <Training> can be declared if suspending is possible. Once declared, suspending must be performed.)
15-8-5Immediate-Type Effects
15-8-5-1An immediate-type effect will always trigger as soon as its trigger conditions are met, then the effect can be activated. However, these effects will interrupt right before the cause of a rule or effect, unlike trigger-type effects. These include effects with "when X would" or "when X would be removed" in their text, such as "[Your Turn] When this Digimon would digivolve into a card with [Greymon] in its name, reduce the digivolution cost by 1 for each color on that card."
15-8-5-2Activation of immediate-type effects will interrupt right before the cause of such effects. (Example: An immediate-type effect that triggers "when X would be deleted" will trigger immediately before the deletion, and if that "when X would be deleted" effect prevents the card from being removed from the battle area, it isn't deleted.)
15-8-5-3Immediate-type effects will only trigger simultaneously with other immediate-type effects.
15-8-5-4Each immediate-type effect can be activated one at a time until the cause that first interrupted the immediate-type effect is resolved. (Example: If "[Main] Delete 1 of your opponent's Digimon" causes "[All Turns] When this Digimon would be deleted, by deleting 1 other Digimon with [Sukamon] in its name, it isn't deleted" to activate, until the deletion is resolved, the already activated "[All Turns] When this Digimon would be deleted, by deleting 1 other Digimon with [Sukamon] in its name, it isn't deleted" can't activate again.)
15-8-5-5Immediate-Type Effects With Processing Conditions
15-8-5-5-1An immediate-type effect with processing 2 conditions will always trigger as soon as its trigger conditions are met, then the effect can be activated if its processing conditions are met.
15-8-5-5-2Even if an immediate-type effect with processing conditions triggers when its processing conditions aren't met, it can be activated if its processing conditions are later met.
15-9Mandatory Processing and Optional Processing
15-9-1Mandatory Processing
15-9-1-1Mandatory processing refers to text whose action is required.
15-9-1-2The player must choose to execute the content of mandatory processing. A player can't choose to not execute it.
15-9-2Optional Processing
15-9-2-1Optional processing refers to text whose action is optional.
15-9-2-2The player can choose to execute the content of optional processing.
15-10Effect Targets
15-10-1Effect Targets - Players
15-10-1-1"You" or "Your"
15-10-1-1-1If text includes "you" or "your," it affects the player of that card.
15-10-1-2"Opponent"
15-10-1-2-1If text includes "opponent," it affects the opponent player.
15-10-1-3"Both Players"
15-10-1-3-1If text includes "players" or "both players," it affects both players.
15-10-2Effect Targets - Cards
15-10-2-1If text such as "X Digimon" or "X cards" is written on a card, X number of cards or as many cards up to X as possible must be chosen. The individual processing is performed on those cards. (For details, refer to 15-11-1 "Individual Processing")
15-10-2-2If text such as "up to X Digimon" or "up to X cards" is written on a card, up to X number of cards are chosen. The individual processing is performed on 28 those cards. (For details, refer to 15-11-1 "Individual Processing")
15-10-2-3When multiple cards are to be chosen at the same time, the same target card can't be chosen multiple times. (Example: If an effect reads "[Main] 3 of your opponent's Digimon get -5000 DP and <Security Attack -1> until the end of their turn," the same Digimon can't be chosen 3 times.)
15-10-2-4"All"
15-10-2-4-1When "all" is specified, the target cards aren't chosen. Overall processing is performed on those cards. (For details, refer to 15-11-2 "Overall Processing")
15-11Individual Processing and Overall Processing
15-11-1Individual Processing
15-11-1-1Individual processing refers to when a target is chosen for processing. Individual processing affects the chosen target. This refers to processing where a target is chosen, including text such as "[Main] 1 of your opponent's Digimon gets -7000 DP for the turn."
15-11-1-2If the chosen card for individual processing becomes a new card, that individual processing will be lost. (For details, refer to 3-1-3-1 "New Cards")3-1-3-1
15-11-1-3Individual Processing With Conditions for Choosing a Target
15-11-1-3-1When individual processing has conditions for choosing a target, only a target that meets those conditions can be chosen. This refers to processing with conditions for choosing a target including effects such as "[Main] Choose 1 of your opponent's Digimon with no digivolution cards. That Digimon can't attack or block until the end of your opponent's next turn."
15-11-1-3-2When a target is affected by an effect where individual processing has conditions for choosing a target, the effect will continue affecting the target, even if the target no longer meets the conditions after 2 being affected. (Example: If a Digimon is affected by an effect such as "[Main] Choose 1 of your opponent's Digimon with no digivolution cards. That Digimon can't attack or block until the end of your opponent's next turn," that Digimon can't attack even if it later gets a digivolution card.)
15-11-2Overall Processing
15-11-2-1Overall processing refers to when a target isn't chosen for processing. Overall processing affects cards overall. This refers to processing where a target isn't chosen, including effects with text such as "[On Play] [When Digivolving] All of your opponent's Digimon get -5000 DP for the turn."
15-11-2-2Overall processing that is continuous will also affect targets that are added later. (Example: If an effect reads "[When Digivolving] [On Deletion] All of your opponent's Digimon get -5000 DP for the turn," Digimon placed in the battle area after this effect activates will also get -5000 DP.)
15-11-2-3Overall Processing With Conditions for Affecting Targets
15-11-2-3-1When overall processing has conditions for affecting targets, the processing affects all of the targets that meet those conditions. This refers to processing with conditions for affecting targets including effects such as "[All Turns] None of your opponent's Digimon with no digivolution cards can attack or block."
15-11-2-3-2When overall processing has conditions for affecting targets, as soon as a target no longer meets the conditions after being affected, the processing will no longer affect that target. (Example: While an effect that reads "[All Turns] None of your opponent's Digimon with no digivolution cards can attack or block" is activated, an opponent's Digimon with no digivolution cards can't attack or block, but if it later gets a 29 digivolution card, it will then be able to attack or block.)
15-11-2-3-3When overall processing has conditions for affecting targets, as soon as a target that wasn't affected meets the conditions, the processing will affect that target. (Example: While an effect that reads "[All Turns] None of your opponent's Digimon with no digivolution cards can attack or block" is activated, an opponent's Digimon with digivolution cards can attack or block, but if it later has no digivolution cards, it will no longer be able to attack or block.)
15-12Effects That Add Information and Effects That Change Information
15-12-1Effects That Add Information
15-12-1-1"Effects that add information" refers to effects that add information to a card. These include effects such as "[Main] [Once Per Turn] 1 of your [Marcus Damon] is treated as a 3000 DP Digimon that can't digivolve for the turn."
15-12-1-2Effects that add information can also add information that a card didn't already have.
15-12-1-3An effect that adds information can only add to the play cost, level, or DP of 1 card at a time. If an effect adds information to a card that already has such information, the newly added information will overwrite the previous information.
15-12-1-4If an effect that adds information treats a card as a Digimon, the rules for Digimon will also apply to that card. (For details, refer to 4-2 "Digimon")
15-12-1-5If an effect that adds information adds DP to a card that didn't originally have DP, the added DP will be treated as that card's original DP.
15-12-1-6If an effect that adds information causes a card to be treated as both a Digimon and a Tamer card, an effect activated by that card will be considered both a Digimon effect and a Tamer effect. (Example: When an "[All Turns] Your opponent can't gain memory other than by Tamer effects" effect is activated, the effects of a Tamer that is also treated 3 as a Digimon will still be considered to be Tamer effects, therefore its effects can still gain memory.)
15-12-2Effects That Change Information
15-12-2-1"Effects that change information" refers to effects that change the information on a card. These include effects such as "[Security] Change the original name of 1 of your opponent's Digimon to [Sukamon] (white/3000 DP) until the end of your turn."
15-12-2-2Effects that change information can't change information that a card didn't originally have.
15-12-2-3If an effect changes information on a card that has already been affected by an effect that changes information, the most recently changed information will overwrite the previous information.
15-13Gained Effects
15-13-1Some effects can be gained through other effects.
15-13-2When an effect is gained, the effect and the state of the effect at that time will be carried over, even if a card is placed on top of that card or a card is removed from its stack.
15-14Effect Icons
15-14-1[X Per Turn]
15-14-1-1[X Per Turn] means that an effect can be activated a number of times during 1 turn as specified by X, and each activation counts toward 1 use of X.
15-14-1-2If an [X Per Turn] effect is used X number of times during 1 turn, it won't trigger again during that turn.
15-14-1-3The uses of an [X Per Turn] effect are counted individually for each copy of a card.
15-14-1-4When a player chooses to activate an [X Per Turn] effect, it will count toward 1 use of [X Per Turn], even if the effect's processing can't be executed.
15-14-1-5The number of uses for an [X Per Turn] effect will be reset in the following circumstances.
15-14-1-5-1The turn changed.
15-14-1-5-2The card with that effect is considered to become a new card. (For details, refer to 3-1-3-1 "New Cards")
15-14-2{Hand}
15-14-2-1An effect with the {Hand} icon can be activated when you reveal the card with the effect from your 30 hand.
15-14-3{Trash}
15-14-3-1An effect with the {Trash} icon can trigger and activate while the card with the effect is in your trash.
15-14-4{Breeding}
15-14-4-1An effect with the {Breeding} icon can trigger and activate while the card with the effect is in the breeding area.
15-14-5{Security}
15-14-5-1An effect with the {Security} icon can trigger and activate while the card with the effect is placed face- up in the security stack.
15-15Rules for Effect Text
15-15-1Effects That End an Attack
15-15-1-1If an attack is ended by an effect, the end of attack timing comes immediately after the processing for that effect.
15-15-2"Gains"
15-15-2-1"Gains" means that a target card gains an effect.
15-15-2-2When a target gains an effect, it is affected by that effect.
15-15-3Effects That Reveal Cards
15-15-3-1A card being revealed isn't considered to cause the number of cards in its original area to increase or decrease. However, a card can't be referenced as a card in its original area while it's being revealed. (Example: Even if a card is revealed from a security stack, "when a card is removed from your security stack" effects don't trigger. In addition, even if cards revealed from a deck are trashed, they aren't treated as being trashed from the deck.)
15-15-3-2If the number of cards being revealed increases or decreases, then the number of cards in the original area is considered to be modified. (Example: When cards are revealed from a security stack, then one or more of the revealed cards are trashed, "when a card is removed from your security stack" effects will trigger.)
15-15-3-3Another effect can't increase the number of cards in a single area while all of those cards are revealed.
15-15-3-4Until all of the revealed cards are placed into an 3 area, the processing for revealing cards is considered a single process. (Example: If an effect reads "[On Play] Reveal the top 5 cards of your deck. Add 1 Tamer card among them to your hand. Return the rest to the bottom of the deck," once the remaining cards have been placed at the bottom of the deck, that text is considered resolved as a single process.)
15-15-3-5If a player is to draw a card during processing for revealing a card from the deck, they draw from the unrevealed cards. (Example: When "[When Attacking] Reveal the top 3 cards of your deck. This Digimon may digivolve into 1 green level 6 Digimon card among them without paying the cost. Place the remaining cards at the bottom of your deck in any order" is used to digivolve, the bonus draw for digivolution is taken from the unrevealed cards of your deck.)
15-15-3-6When returning multiple revealed cards to their original state, the player who owns the card that caused the action to be performed is the player who chooses the order in which the cards are returned. (Example: If an effect reads "[On Play] Reveal the top 4 cards of your deck. Add 1 card with [Gammamon] in its text among them to your hand. Return the rest to the bottom of the deck," is used to return multiple cards to the deck at the same time, the player who activated this effect chooses the order in which the cards are placed at the bottom of the deck.)
15-15-3-7Effects that reveal cards have 2 types: "Reveal" and "search"/"look at."
15-15-3-8Revealing Cards
15-15-3-8-1"Revealing" one or more cards means to reveal them to both players.
15-15-3-9"Search"/"Look At"
15-15-3-9-1"Searching" an area or "looking at" certain cards refers to cards that are only revealed to a specific player.
15-15-3-9-2If a player isn't specified in text, only the player that activated the effect searches/looks at the cards.
15-15-3-9-3After searching an area or looking at cards, the cards are returned according to the rules for the respective area.
15-15-4Effects that add or reduce an effect's numerical value
15-15-4-1An effect that adds to the numerical value of an effect will add to the value shown in text.
15-15-4-2An effect that reduces the numerical value of an effect will reduce the value shown in text.
15-15-4-3Effects that add or reduce an effect's numerical value can't add or reduce a numerical value that isn't shown in text for an effect. (Example: A "[Your Turn] Add 1000 to the maximum your DP-based deletion effects can delete" effect can't add to the maximum of a "[When Attacking] Delete 1 of your opponent's Digimon with DP less than or equal to this Digimon's DP" effect.
15-15-5"Isn't affected by effects" cards
15-15-5-1When a card isn't affected by effects, it won't be affected by processing caused by effects. (Example: Even if a card that isn't affected by effects is chosen for an "[On Play] Suspend 1 of your opponent's Digimon" effect, it isn't suspended.)
15-15-5-2When a card isn't affected by effects, then it can be affected again, effects will immediately start affecting that card. (Example: When a -3000 DP effect is applied to a suspended Digimon with an "[All Turns] While this Digimon is suspended, this Digimon isn't affected by the effects of your opponent's Digimon" effect, the Digimon will get - 3000 DP as soon as it's unsuspended.)
15-15-5-3"Isn't affected by effects" cards can still be chosen for effects. (Example: A card that isn't affected by effects can be chosen for an "[On Play] Suspend 1 of your opponent's Digimon" effect, but it isn't affected by that effect and it isn't suspended.)
15-15-5-4Even if a Digimon that isn't affected by effects gains an effect, the Digimon won't be considered to have that effect. (Example: If an effect reads "[On Play] 1 of your opponent's Digimon gains <Security A. -1> until the end of their turn," even if a Digimon that isn't affected by effects gains <Security A. -1>, 3 the Digimon won't be considered to have <Security A. -1>.
15-15-6Effects That Can Replace DigiXros Requirements
15-15-6-1Effects that can replace DigiXros requirements allow cards to replace those shown in brackets in the DigiXros requirement text.
15-15-6-2Effects that can replace DigiXros requirements can't replace DigiXros requirements that specify a card that isn't the same as another. (Example: Effects that can replace DigiXros requirements can't replace a card for "∞ Digimon cards w/[Xros Heart] or [Blue Flare] trait & different card numbers.")
15-15-7Effects That Activate Other Effects
15-15-7-1During the processing of effects that activate other effects, another effect will activate and process. (Example: If an effect reads "[When Digivolving] You may place 1 card with [Royal Knight] in its traits and a play cost of 13 or less from your hand or trash under this Digimon as its bottom digivolution card. Activate 1 of that card's [When Digivolving] effects as an effect of this Digimon. Then, <Blitz>," a [When Digivolving] effect on the card placed as the bottom digivolution card will activate, then <Blitz> will be processed after that effect is processed.
15-15-7-2If multiple other effects will activate, the player can choose their activation order. (Example: If "[When Attacking] Activate 1 of the following effects: If you don't have another Digimon, instead activate all of the following effects" is used to activate all of the other effects, the player can choose their activation order.)
15-15-7-3If an effect that activates another effect has text such as "activate as this card's effect," the card that activated this effect will be considered to have activated the effect.
