Q:Can I trash just 2 digivolution cards for the conditions of this card's inherited effect?

A: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 trash the specified number of digivolution cards.

Q:What does "end the attack" mean, exactly?

A:After this effect activates, the current timing makes a transition to the end of attack timing. For example, if this effect activates during the attack declaration timing, it will make a transition to the end of attack timing. A transition to the counter timing or block timing won't occur, and the attack won't succeed.

Q:Can an "end the attack" effect end an attack by a Digimon that isn't affected by effects?

A:Yes, such attacks can be ended. "End the attack" effects are effects that change the timing, they don't affect an attacking Digimon.
