Yuri's Independent Actions (AB/W31-E058R RRR) [Angel Beats! Re:Edit]

[AUTO] When this card is placed on stage from your hand or by a"Change" effect, you may put the top card of your clock into your waiting room. [AUTO] [(1)] When this card attacks, if a card named "After the Battle" is in your climax area, you may pay the cost. If you do, choose a character in your waiting room, return it to your hand, choose one of your {Death} characters, and that character gets +3000 power until end of your opponent's next turn.
