Vaekros, Gravekeeper

Your graveyard can’t be targeted or exiled by opponents.

Whenever a spell your opponnents control destroy a permanent you control, you may pay {u}{p/u}. If you do, return up to one target instant or sorcery spell with mana value 3 or less from your graveyard to your hand.

He waits in silence, not for the living — but for those who try to steal from the dead.
