Performage Showdown

You can only use this Skill's second, third, and fourth effects once per turn. 1: You cannot Special Summon (excluding Special Summons from the Extra Deck) monsters, except for "Performage" and Level 4 Spellcaster monsters. 2: Send 1 "Performage" monster from your hand to the Graveyard, and then add 1 "Performage" monster from your Deck or 1 "Polymerization" from outside of your Deck to your hand. 3: Shuffle 1 monster on your field into the Deck, and then play 1 "Performage" monster from your Deck to your field in face-down Defense Position. (Its battle position can be changed.) 4: If you control 4 face-up monsters on your field, reveal 1 "Polymerization" in your hand, and then all of the monsters on your field can be treated as "Ancient Gear" monsters when used as Fusion Materials this turn.
