Gluttonous Ogre

Trample, pillage 2 (Whenever this creature deals combat damage to a player, exile the top two cards of that player's library. You may cast those cards until end of turn. You may spend mana as though it were mana of any color to cast them.)
At the beginning of your upkeep, target opponent gains control of Gluttonous Ogre unless you sacrifice another creature.
