Oryx, the Taken King

Flying, Deathtouch, Lifelink

Whenever a creature would be put in a graveyard from the battlefield, exile it instead with a Taken counter on it. You may look at and play these cards for as long as they remain exiled this way, and you may spend mana as though it were mana of any color to cast these spells. It becomes a colorless Taken creature in addition to its other types.

{t},{p/w}{p/b}{p/g}: Destroy target creature. It can't be regenerated.
