Burning Curiosity (ECL)

Sorcery

As an additional cost to cast this spell, you may blight 1. (You may put a -1/-1 counter on a creature you control.) Exile the top two cards of your library. If this spell's additional cost was paid, exile the top three cards instead. Until the end of your next turn, you may play those cards.

Cinders are drawn to any heat, at any cost.
