When an opponent's monster declares a direct attack, if you control a card in your Spell & Trap Card Zone: You can Special Summon this card from your hand. If you do: Destroy all cards in your Spell & Trap Card Zone, and if you do, inflict 200 damage to your opponent for each card destroyed by this effect. You cannot Special Summon any monsters, except Machine-Type monsters.
