You can only use this effect of "Ancient Gear Frame" once per turn. If this card attacks, your opponent cannot activate Spell/Trap Cards until the end of the Damage Step. If this face-up card in its owner's control leaves the field because of an opponent's card effect: You can Special Summon up to 3 "Ancient Gear Golem" and/or "Ancient Gear Golem - Ultimate Pound" from your hand, ignoring their Summoning conditions.
