Helmut Zemo, Mastermind (Extended Art) (MSC-331)

Whenever Helmut Zemo attacks, you may cast target instant or sorcery card with mana value less than or equal to his power from your graveyard. If that spell would be put into your graveyard, exile it instead. If you cast a spell this way, put a +1/+1 counter on Helmut Zemo.
