Terrero, the Vileblooded

Flying
Whenever Terrero, the Vileblooded deals combat damage to a player, exile the top two cards of that player's library. You may look at and play cards exiled this way for as long as they remain exiled, and you may spend mana as though it were mana of any type to cast them.
Whenever you play a card you don't own, you draw a card and you lose 1 life.
