Moon Barrier

[Ryusei the Morning Star]

Spell Quick-Play
(1) When an attack is negated: Activate 1 of these effects.
-It is now the End Phase of this turn.
-Target 1 “Utopia” Xyz Monster you control; its ATK becomes double its original ATK until the end of this turn.
(2) If a “Utopia” Xyz Monster you control would detach 1 Xyz Material to activate its effect, you can banish this card from your Graveyard instead.

Yo, that's actually a pretty cool card. Skipping right to the End Phase seems super troll. I doubt it will actually be any good, but it'll be meme-worthy.

[Atypical-Abbie]

It's so weird that Double or Nothing! is so important for Yuma's playstyle that a card like this exists.

[Progenitor]

yo fam Double or Nothing + this beat for 10,000.

:SeemsGood:

Honestly, I'm tempted to say this card outright sucks.

 

It's cute as a concept, but it can only be used when an attack is negated, and that's so restrictive, it hurts, even among the Utopias. Because only No.39 and Roots have an attack negation effect. And sure, it either ends the turn (which is trolly and adorable), or doubles a Utopia's ATK for the turn. Okay, unlike Double Up Chance, it doesn't let you USE that buffed attack if you negated your own attack, unless you negated a different monster's attack entirely.

 

The Grave effect is solid, though, because Utopias love using their Materials. But I'm pretty sure it's going to have the same rules as things like Brain Research Lab, in that if you can't pay the cost NORMALLY, you can't substitute the cost, so if a Utopia is out of Materials, I don't think you can use this, because you can't activate the Utopia's effect normally.
