Do I or my opponent choose the card to be trashed from their hand when I activate this card's inherited effect?
Your opponent chooses.

Does this card’s inherited effect activate when the Digimon with this card in its digivolution cards is deleted by <Retaliation> on a battled opponent's Digimon?
Yes. It activates because the Digimon is deleted by the <Retaliation> effect, not by battle.
