Reasoning [RA01-EN052] - (Prismatic Collector's Rare) 1st Edition

Your opponent calls a Monster Card Level. You then pick up (not draw) cards from the top of your Deck until a monster is picked up. If that monster is the same Level as the one called by your opponent, all picked up cards are sent to the Graveyard. If not, Special Summon the monster that was picked up in face-up Attack or Defense Position and send the remaining cards that were picked up to the Graveyard.
