While you control no monsters: Target 1 face-up card you control; destroy it, and if you do, Special Summon 1 Ancient Gear monster from your Deck, ignoring its Summoning conditions. You can banish this card from your Graveyard, then target 1 face-up card you control; destroy it, and if you do, Special Summon 1 Ancient Gear Token (Machine-Type EARTH Level 1 ATK 0 DEF 0). You can only use 1 Ancient Gear Catapult effect per turn, and only once that turn.
