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.

Astral's true ace, as it's the only Number he use on-screen that Yuma never use on-screen.
Unfortunately this card is clearly too strong for early Zexal world era, so in DL I think Astral will either have no ace card, or just share the base Hope with Yuma.
besides, this card is from the final duel in the series, so I don't think we'll going to see this card in DL for at least 2 or 3 years after Zexal world gets opened, depending on how fast Konami wants to go.
