If your opponent Normal or Special Summons a monster(s): You can target 1 of them; choose 1 of your face-down banished "Xenovader△" monsters with the same Attribute, and either add it to your hand or Special Summon it, also for the rest of this turn, you cannot choose the same Attribute again with this effect of "Xenovader△ Judgment", and you cannot activate cards or effects, except "Xenovader△" cards or effects.
Once per battle, during damage calculation, if your "Xenovader△" monster battles an opponent's monster and you have no cards in your Deck: You can make that opponent's monster's ATK become 0.
