Party Thrasher — Modern Horizons 3 #419

Noncreature spells you cast from exile have convoke. (Each creature you tap while casting a noncreature spell from exile pays for or one mana of that creature's color.)

At the beginning of your first 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.
