* At the start of your opponent's Battle Phase: You can send this face-up card from your Spell & Trap Zone to the GY; monsters your opponent controls cannot target "Ancient Warriors" monsters for attacks this turn.
* When an opponent's monster declares an attack: You can banish this card from your GY; Special Summon 1 "Ancient Warriors" monster from your Deck.
