Cannot be destroyed by battle except with "Number" monsters.

The ATK of any monster that battles this card becomes 0 during the Battle Phase only. When this card is destroyed: Destroy all monsters on the field, also return all Spell and Trap Cards that were destroyed on the field this turn to the same position they were in before they were destroyed. Once per turn: You can detach 1 Xyz Material from this card; during each Battle Phase this turn, this card gains ATK equal to the total Ranks of all face-up monsters currently on the field x 1000, until the end of the Battle Phase.
