2 or more 'Number' Xyz Monsters with the same Rank that have Xyz Materials
Once per turn: You can Special Summon Rank 9 or lower 'Number' monsters with 3000 or less ATK from your Extra Deck that have different Ranks from each other, up to the number of Xyz Materials attached to this card, but their effects are negated, then detach 1 Xyz Material from this card. For the rest of this turn, any battle damage your opponent takes is halved, also you cannot Special Summon monsters. Cannot be destroyed by battle or card effects while you control another 'Number' Xyz Monster.
