I don't know why you've got 3 copies of Lio dancer, because you ain't summoning it that many times. I'm not even sure you should have two. Also, you can do rank 4, 3 and 2 plays, so I'd look at picking up some stuff for that. I mean, when it comes to money options, Castel, 101 and Utopia the Lightning are all Rank 4 staples that can be used in just about anything with level 4s, but they are pricey. Granpulse is a good S/T remover, and the Phantom Knights of Break Sword are also useful.

Also, I don't see any King of the Swamps, which is pretty useful in this deck because it can replace Cat and Panther for fusions or search for Poly in a pinch.

Running Dark Law is an option, but you're using a lot of cards just to do your main decks thing, so having to rely on Mask Change II is... not the best.

Oh, and Dark Eruption is useful for getting back material. Still not as good as Salvage, but what is? Seriously, a water attribute fusion archetype would be insane because of that card.
