Notes & Combos
I was struggling in low Legend with a 24 cards consistency-oriented list, then I swapped to this 30 cards list and reached KoG in basically no time.
In case you're not doing it already, play Different Dimension Ground. If you manage to go 1st and find it in your opening hand, you have good chances of shutting down all/most of your opponent plays... and if you don't open it, you can still try to draw it with Liquid Soldier/Cross Keeper.
About Yubel... I play her because Kluger is the only Neos Fusion-related monster who seems reasonable to summon on turn 1. It doesn't feel good to go 1st, open Neos Fusion and summon Brave Neos or Rainbow Neos... because none of them has any kind of protection (besides Neos Fusion itself) or interruption. On the other hand, Kluger is harder to deal with thanks to his own effect (and also to the fact that most of the times he gets replaced by Neos Wiseman, which can't be destroyed by card effects).
So... if you desperately need DDG you can Neos Fusion into Brave Neos, send Cross Keeper to the Graveyard and draw. But if you have DDG already, or if you sent Cross Keeper to the Graveyard with Draconic Contact already, then Kluger is definitely the way to go.
