"Rainbow Neos" Rating Score by シエスタ

With his ultimate Blue-Eyed class ATK that surpasses Obelisk and Zarc, he boasts high combat power. On the effect side, he requires more field cost for heavy fusions except GY Bounce, but whole Deck Bounce and very powerful ones.
Fusion materials have many different elements such as not being able to use fusion substitutes, but both are easier to search than when they first appeared, and the quality of fusion support has also improved, so the summoning difficulty is low. By using Rainbow Dark as a material, the conditions for summoning Chaos are also in place, and you can pull together the Chaos Monarch Dragon from Melody and apply this rush.
The difficulty is that it has no resistance, and backing up, such as God Binding, is essential to maintain, but it is easy to decide the game without turning the opponent's turn with its own effect, and it is easier to summon than before, so don't worry about the second body. You can also aim for a summon.
A dedicated build is desirable for success, but I think it's a monster with a powerful effect that's worth it, and a monster with this kind of gorgeous fusion material, which is unusual for a battle-level performance.
