Once per turn: You can detach 1 Xyz Material from this card; this card gains ATK equal to the combined Ranks of all Xyz Monsters on the field x 1000, until the end of your opponent's turn. When this card is destroyed by a card effect: You can destroy as many monsters on the field as possible, then each player Sets 1 Spell/Trap Card from their Graveyards to their side of the field. When an opponent's monster declares a direct attack while you have no cards in your hand and control no cards: You can Special Summon this card from your Graveyard.
