Haste\nProwess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)\nValiant — Whenever Emberheart Challenger becomes the target of a spell or ability you control for the first time each turn, exile the top card of your library. Until end of turn, you may play that card.
