Q:If I use this card, do I lose 2 memory every time my opponent attacks with a Digimon?

A:Your opponent loses the 2 memory. The memory marker will be moved 2 spaces towards you every time your opponent attacks with a Digimon.

Q:I use this card. During my opponent’s next turn, if they play a new Digimon or move a Digimon from their breeding area to their battle area, will those Digimon have “[When Attacking] Loses 2 memory” from this card’s effect?

A:Yes. The effect reads, “All of your opponent’s Digimon,” so any Digimon that enter the battle area after you use this card are still affected.

Q:I use this card. During my opponent’s next turn, they attack me with their Digimon's effect while I have 1 or more memory. Does my opponent still lose 2 memory?

A:Yes. Even if you have 1 or more memory, the attack with still takes place during your opponent's turn, which means that this card's effect is still active, and your opponent still loses 2 memory.
