If your opponent controls a monster: You can Fusion Summon 1 Fusion Monster from your Extra Deck that mentions "Ancient Gear Golem", by banishing its materials from your field and/or GY, including "Ancient Gear Golem" you control, and if you do, it can make up to 3 attacks during each Battle Phase. You can only use this effect of "Ancient Gear Duel" once per turn.
