Number V104: Finalswarm Sorcerer

Must be Special Summoned by "Rank-Up-Magic Infestation Evolution", and cannot be Special Summoned by other ways. Cannot be destroyed by battle except with "Number" monsters. Up to twice per turn, when your opponent Special Summons a monster: Send 1 random card from your opponent's hand to the Graveyard. If this card has "Number 104: Masquerade" as an Xyz Material, it gains this effect.
● Once per turn, during either player's turn, when your opponent activates a monster effect: You can detach 1 Xyz Material from this card; negate the activation, and if you do, destroy that card, then you can inflict damage to your opponent equal to the destroyed monster's ATK.
