After declaring a digivolution and revealing this card, you can activate the effect immediately before choosing the card to digivolve. When you choose to activate it, if the "by" condition is met, you may also choose one of your Tamers in addition to Digimon for the card to digivolve. The chosen Tamer is also treated as a level 6 Digimon during this digivolution.

No, you can't. After declaring a digivolution and activating this card's 1st effect, you must choose one of your cards to digivolve and then digivolve it, just as in the procedure for normal digivolution. In addition, you can't declare digivolution into this card in the first place unless there is a card on the field that you can digivolve.

Yes, you can.

Yes, you can.

No, you can't. A "by" condition can't be met if only some of the required actions are performed. The conditions for this inherited effect require you to return the specified number of cards to the bottom of the deck.

Yes, you can.

Yes, you can activate this card's 1st effect and digivolve it. However, you can't digivolve one of your Tamers into this card unless the conditions for activating this card's 1st effect are met.

No, you can only digivolve the chosen Digimon. You use BT18-096 [Lord of Devastation and Rebirth]'s [Main] effect to choose one of your Digimon or Tamers, then digivolve the chosen card. You can activate this card's 1st effect, but you can't change the card to digivolve.

You activate this card's 1st effect first. You declare digivolution of this card, then activate this card's 1st effect immediately before choosing the card to digivolve. After that, you choose your Digimon to digivolve and process EX1-071 [Win Rate: 60%!]'s "would digivolve" effect. If you would digivolve from a Tamer, EX1-071 [Win Rate: 60%!]'s effect can't be processed.

No, it can't. Even if a card digivolves from a card that was placed on the field in the same turn, it can't attack during that turn. It can only attack in the turns after it's played.

No, it isn't. Lower text only becomes an inherited effect when it's marked as an "Inherited Effect".

Yes, you reveal them to your opponent. The cards to be returned are revealed, then both players confirm the order in which they're returned to the bottom of the deck.

Any color of card can be digivolved from.
