Question 1

If my opponent has 7 or more Digimon in play, does this card’s effect get reduced to negative 1, effectively gaining me a memory for using it?

Accepted Answer

No. It just reduces the cost of the card to 0. Note that in general, costs can’t be reduced to less than 0.

Question 2

I use this card, then attack my opponent. During the security check, I flip over a Digimon card with the effect, “[Security] At the end of the battle, play this card without paying its memory cost.” What happens to this Security Digimon?

Accepted Answer

After the battle between the attacking Digimon and Security Digimon, the effect prevents the Digimon from being played, so it's placed in the trash.

Question 3

My opponent used this card on my [BT7-063 DarkKnightmon]. [DarkKnightmon]'s [All Turns] effect is a "when this Digimon would be deleted" effect that interrupts deletion when it activates, but can I use this card's "your opponent can't play Digimon by effects until the end of their turn" effect to prevent [SkullKnightmon] and [DeadlyAxemon] from being played from [DarkKnightmon]'s digivolution cards?

Accepted Answer

Yes, they can't be played. This card's [Main] effect was changed to "Your opponent can't play Digimon by effects until the end of their turn. Delete all of your opponent's Digimon with 6000 DP or less." Therefore, first the effect that prevents playing Digimon is applied, then Digimon with 6000 DP or less are deleted. Please see the notices regarding changes to the rules/rulings on the official website.

Question 4

If this card's effect is activated on the opponent's turn, how long does the effect last?

Accepted Answer

When the effect of this card is activated on the opponent's turn, it lasts until the end of that turn.

Question 5

What does a "your opponent can't play XX by effects" effect do, exactly?

Accepted Answer

Such effects prevent your opponent from playing XX by effects. With this card's effect, your opponent can no longer play Digimon by effects such as BT10-018 [Gaossmon]'s [On Deletion] effect or BT16-048 [TyrantKabuterimon]'s [When Digivolving] effect. This effect affects the opponent player.

Question 6

I activate a "your opponent can't play XX by effects" effect, and in the same turn, my opponent activates an effect that reveals cards and plays a specified card from their deck. Is the card revealed from the deck but not played?

Accepted Answer

Yes. Your opponent reveals cards, but then doesn't play the specified card.

Question 7

Can an opponent's Digimon be played if I activate a "your opponent can't play Digimon by effects" effect, and in the same turn, I activate an effect such as EX5-060 [Dragomon]'s [On Play] [When Digivolving] effect that plays an opponent's Digimon card?

Accepted Answer

Yes, it can be played. "Your opponent can't play Digimon by effects" is an effect that prevents your opponent from playing Digimon by effects. Your effects can still play an opponent's Digimon.

Question 8

Can my Digimon be played if I activate a "your opponent can't play Digimon by effects" effect, and in the same turn, my opponent activates an effect such as EX5-060 [Dragomon]'s [On Play] [When Digivolving] effect that plays an opponent's Digimon card?

Accepted Answer

No, it can't be played. "Your opponent can't play Digimon by effects" is an effect that prevents your opponent from playing Digimon by effects. Your Digimon can't be played by an opponent's effect.
