3 Level 5 monsters This Xyz Summoned card cannot be destroyed by card effects.

You can detach 1 material from this card; this card gains ATK equal to the total original ATK of all other monsters on the field, then, if this card has a DARK Xyz Monster as material, negate the effects of all other face-up monsters on the field.

After this effect resolves, you cannot declare attacks with other monsters for the rest of this turn.
