Number 99: Utopic Dragon (MP15-EN190)

3 Level 10 monsters

You can also Xyz Summon this card by discarding 1 Rank-Up-Magic Spell Card and using a Utopia monster you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials on this card.) Once per turn: You can target 1 Number monster in your Graveyard; Special Summon it in Defense Position but its effects are negated. During either player's turn when a monster effect is activated that targets this face-up card: You can detach 1 Xyz Material from this card; negate the activation and if you do destroy that card.
