At the beginning of combat on your turn, if you've cast a noncreature spell this turn, discover 6. (Exile cards from the top of your library until you exile a nonland card with mana value 6 or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)
