* When this creature attacks, you and your opponent play "Gachinko Judge". If you win, you may put a non-evolution Dragon from your mana zone with a cost less than the number of cards in your mana zone into the battle zone.
(Gachinko Judge: Each player reveals the top card of their deck and puts it at the bottom of their deck. If your opponent's revealed card's cost is equal to or less than your revealed card's, you win)
