i really like the look of this deck, but i feel like its begging for Levia Dragon and Amphibious Bugroth...also U should add gravity bind x2...since almost all your monsters will go under it, its bound to annoy your opponent...i love penguin soldier in water decks, and gives more reason to run Gravity bind!!!
-Sangan
-Bes Crystal Core x1
-Nightmare Penguin x1

+Bugroth
+Mother Grizzly x1
+Levia Dragon

-Dust Tornado
-Compulsary Evac
+Gravity Bind x2

Hopefully that helps...Good Deck (8.5/10) :)

- CEDevice
- Dust Tornado

+ 2 Spritual Water Art

Works amazingly well and you can get the monsters that you tributed for it with Salvage. Also a chainable trap...you should try it out.

I too think this could use a Levia since it does help your quest for field control. Bugroth should be added if you want some big hits here and there, as it does not contribute to field control. Also, some Water Art-Aoi can greatly help you control the hand. If I had to suggest removing something, I'd say Morphing Jar, a Crystal Core, and a Dust Tornado. Hopefully, you are side decking some Noblemen.

Good job on getting to Abyss Soldiers. Must have been hard to get them.

I like the feel of the deck. Everything's so one-turn-drop-able.

The LeviaDragon does help the whole field-control theme, though I think it or your 3rd copy of Crystal Core are both good choices.

With the Levia in:
- 1 BES Crystal Core
- 1 Penguin Soldier
+1 LeviaDragon Daedalus
+1 Nightmare Penguin
- 1 Smashing Ground
+1 Mermaid Knight

You have plenty of bounce, the Penguin Soldier isn't very useful after it's been flipped, and it does nothing to help you, except bounce 2 that one time (unless you have Tsukuyomi). You might as well go for something that can boost your water monsters than a flip effect. Mermaid Knights are perfect for your deck, and I think having a second copy might not be a bad idea.

so let me get this straight.. you just want to.. bounce the monsters?... You're missing an imporatant strategy

-2 Smashing Grounds
-1 Book of Moon
+3 D.D. Designator

My friend did a deck like this before the ban, we called it the "Hunter" deck.. basically it was "PULL!" *BANG!*, bonce and kill, fun stuff, pretty efficient. He used Mind Crush as well but lets not bother with that right now, hmm?

I'm not sure where, but fit in MORE water monsters. Remember, Sinister is gone. You should try and get your monster count up to 18-20, and have more water monsters than everything else combined to make abyss soldier effective. This will nearly garuntee your direct attacks, and you'll be able to rush your opponent pretty efficiently for the win.
