SPELLSpell

Your opponent declares a monster Level. Reveal cards from the top of your Deck until you reveal a monster that can be Normal Summoned. If that monster is the same Level as the one declared by your opponent, send all revealed cards to the Graveyard. If not, Special Summon the revealed monster, also send the remaining cards to the Graveyard.
