The next YCS prize card has been revealed and it is Number 93: Utopia Kaiser. Looks like Number collectors will have to wait on another card for their collection.
Number 93: Utopia Kaiser
Rank 12 / LIGHT / Warrior / 2500 ATK / 2000 DEF
2 or more “Number” Xyz Monsters with the same Rank, that have Xyz Material
Once per turn: You can Special Summon Rank 9 or lower “Number” monsters with 3000 or less ATK that have different Ranks from each other from your Extra Deck, up to the number of Xyz Materials with different names attached to this card, but their effects are negated, then detach 1 Xyz Material from this card. For the rest of this turn, unless this effect was negated, you cannot Special Summon, and any battle damage your opponent takes becomes halved. While you control another “Number” Xyz Monster, this card cannot be destroyed by battle or card effects.
