Noncreature spells you cast from exile have convoke. (Each creature you tap while casting a noncreature spell from exile pays for {1} or one mana of that creature's color.)
At the beginning of your precombat main phase, you may discard a card. If you do, exile the top two cards of your library, then choose one of them. You may play that card this turn.
