You can only control 1 face-up "Number I" monster. This monster gains ATK equal to the highest original ATK on the field. If "Number 57: Tri-Head Dust Dragon" is attached to this card as an Xyz Material, this card gains this effect.
● Once per turn: You can detach 1 Xyz Material from this card to declare 1 Card Zone Type, (Monster Card Zones, or Spell & Trap Card Zones); any unoccupied Zones of that type cannot be used, any occupied Zone(s) with Set cards in them of that type cannot activate those Set cards, and an occupied Zone of that type that becomes unoccupied cannot be used, until the end of your opponent's next turn.
