Rite of Eternity

Whenever an opponent casts a creature spell, you may search your graveyard for two creature cards with a converted mana cost equal to or less than the opponent's casted spell. If you do, put one onto the battlefield and exile the other creature.
{3}{b},{t}: Return exiled creature to it's owners hand.
