Altair Ibn-La'Ahad
[Assassin's Creed]

First strike
Whenever Altaïr Ibn-La'Ahad attacks, exile up to one target Assassin creature card from your graveyard with a memory counter on it. Then for each creature card you own in exile with a memory counter on it, create tapped and attacking token that's a copy of it. Exile those tokens at end of combat.
