3 Level 5 monsters
If this card attacks, your opponent cannot activate any Spell/Trap Cards until the end of the Damage Step. If this card has a "Utopia" monster as an Xyz Material, it gains this effect.
●When this card declares an attack on a face-up monster your opponent controls: You can detach 1 Xyz Material from this card; negate that opponent's face-up monster's effects, also this card gains ATK equal to that opponent's monster's ATK. These changes last until the end of this turn.
