While you control a “Dinowrestler” monster, each player can attack with only 1 monster during each Battle Phase. If your "Dinowrestler" monster attacks an opponent's monster, it gains ATK during damage calculation only. If your opponent controls more monsters than you do: You can banish this card from the GY; Special Summon 1 "Dinowrestler" monster from your Deck. You can only use this effect of "World Dino Wrestling" once per turn.
