{R} Dark Apostle [Universes Beyond: Warhammer 40,000][40K 075]

Gift of Chaos — {3}, : The next noncreature spell you cast this turn has cascade. (When you cast that spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
