I used this deck at a local tournament last weekend and i wiped the floor with everyone else there (almost all of the decks were Chaos!!!!) I just wanted to know if anyone had any suggestions on what i should add or take out of this deck any help will do so don't be afraid to make a suggestion. Will return the favor.

Here's my deck: total 40 cards:

Monsters: 17
Levia-Dragon - Daedalus x2
Mobius the Frost Monarch x1
Tribe Infecting Virus x1
Mother Grizzly x2
Sangan x1
Yomi Ship x2
Sinister Serpent x1
Amphibious Bugroth MK-3 x2
Magician of faith x2
Tsukuyomi x1
Aqua Spirit x1
Star Boy x1

Spells: 16
A Legendary Ocean x3
Premature Burial x1
Nobleman of Crossout x2
Giant Trunade x1
Swords of Revealing Light x1
Pot of Greed x1
Creature Swap x1
Heavy Storm x1
Delinquent Duo x1
Scapegoat x1
Graceful Charity x1
Snatch Steal x1
Mystical Space Typhoon x1

Traps: 7
Call of the Haunted x1
Ceasefire x1
Gravity Bind x2
Torrential tribute x1
Dust Tornado x1
Judgement of Anubis x1 (to protect my Legendary oceans mainly)

So that's my water deck it runs really good, but there could still be some room for improvement. Like I said any help would be appreciated.

this is a good deck i would rate it 9.0 out of 10 Good work. I think you need to put in a umi or 2 though.

don't know much about water decks but here's what i will do:
-1 ceasefire
+1 ring of destruction
-1 yomi ship
+1 mermaid knight

nice deck 9/10 :)
and by the way.. i run chaos..LOL............

sorry for correcting you but i think i should tell u .. ALO is treated as umi, so u can't have 3 umi and 3 ALO.. and i prefer ALO because it rocks in a water deck, and umi.. just meh...

Waters Deck....Now this I know how to fix
I've been running one for quite some time and they are great. There are 2 main types of water deck you can build: Field Disruption or Gravity Bind Beatdown. I can give you my take on a Field Disruption.

First, lets look at your monster lineup

Levia-Dragon - Daedalus x2
Mobius the Frost Monarch x1
Tribe Infecting Virus x1
Mother Grizzly x2
Sangan x1
Yomi Ship x2
Sinister Serpent x1
Amphibious Bugroth MK-3 x2
Magician of faith x2
Tsukuyomi x1
Aqua Spirit x1
Star Boy x1

Now here are my sugestions
- 2 Yomi Ships
There nice and all but there is much better disruption for water deck. Try 2 Penguin Soldiers instead. Gives you a bit more of a field advantage.IF you prefer something with a bit more powerfull defense, try Nightmare Penguins.

Next up, id remove Aqua Spirit & Starboy for 2 Abyss Soldiers (see below)
This guy can get under G-Bind & is a 2000 beatstick when ALO is active. Plus he can clear the field with his effect.

Now as for your Tributes, keep 1 Levia and add 1 more Mobius. Mobius effect is way to versatile not to run 2 in a Water.

Id lose the Swords of Revealing Light (ill explain why further down. I'd also remove Heavy Storm, it can hurt you more then your opponent. Id replace both of does card with 2 Salvages. They could bring back some monster that you discard for Abyss Soldier to your hand.
Remove Delinquent Duo and Creature Swap for 2 Terraforming, it will increases the chances of getting ALO in your hand.

Now to Traps.
Id add in 2 Tornado Walls to replace Ceasefire and Judgement of Anubis. Jugement of Anubis is nice but to specific and with Terraforming (and Magician of Faith), you dont have to worry as much about ALO bieng destroyed

So once done your Deck should look somthing like this

~~Monsters~~
Levia-Dragon - Daedalus x1
Mobius the Frost Monarch x2
Tribe Infecting Virus x1
Mother Grizzly x2
Sangan x1
Penguin Soldier x2
Sinister Serpent x1
Amphibious Bugroth MK-3 x2
Magician of faith x2
Tsukuyomi x1
Abyss Soldier X2
~~Spells~~
A Legendary Ocean x3
Premature Burial x1
Nobleman of Crossout x2
Giant Trunade x1
Salvage x2
Pot of Greed x1
Terraforming x2
Scapegoat x1
Graceful Charity x1
Snatch Steal x1
Mystical Space Typhoon x1
~~Traps~~
Call of the Haunted x1
Tornado Wall x2
Gravity Bind x2
Torrential tribute x1
Dust Tornado x1

Here's my rating
10/10 for not having anyof the quote/unquote staple monster (Breaker, BLS - EoB, etc) TIV and Sinister belong there since they are water.
8/10 for originality. Water is not play very much (not in my area anyways).
8/10 for playability

Thanks For the R8/ Fixes Guys :)
Thanks i was actually thinking about making these Exact same changes now i have the Penguin Soldiers to replace the Yomi Ships, but I don not have the Abyss Soldiers so i'll have to get my hands on them(i've been looking for a while now), and i'll have to get another Mobius(i can get one easily), but I will definately make those changes.

Now then I don't think that i'll remove Creature swap any time soon cause i usually swap one of my mother gizzlies then attack it getting another monster on my side of the field plus my opponent's monster(swarm) giving me a huge field advantage in most cases.
Delinquent Duo also stays in here for now(hand advantage is as good as field advantage), but i will add in the salvages probably for heavy storm and maybe Delinquent duo i'm not sure or i'll probably just put in another Giant Trunade or something.
Also i don't think that my monsters Rely too much on ALO to add two Terraformings to my deck, but i'll probably add the any ways to boost deck speed.
Now to Traps.
I totally agree with you on this the only reason that i have Judgement of Anubis in this deck is that most spell/trap removal are spell cards (MST/Heavy Storm etc.)but i think i will take this out and ceasefire was more of a finishing card.
Anyways thanks a lot man i think i'll make all of these changes :)

Thanks i tried running Mermaid knight, but it wasn't that good and ring of destruction doesn't fit in here very well, but thanks any ways
There's nothing wrong with Chaos my cousin runs a chaos deck and i practice with him so i have a lot of experience against chaos and this deck is very good against a chaos deck.

Thanks for the rate man, but i already have 3 ALOs adding two more umis would be bad top decking plu ALO is alot better.

Does anyone else have any suggestions for this deck?

This is a great water deck....The spells look fine, And so do the traps..

- Star Boy...Theirs better things than this

- Yomi Ship...1 is enuff removal

+ Mermaid knightx2...These are almost staple in a water deck!!!

Im sorry i dont know much about water decks...so 9/10

Please return the favor and r/f the deck in my sig. Thanks

take out the mk3s and yomiships 4 mermaid knights, breaker, and ring of destruction

Hmmm...this is a pretty good water deck. The JoA in here is an amazing asset because of the need to protect ALO. However, I would recommend:

- Yomi Ship
+ Terraforming

Terraforming would give you the speed you need to get to your ALO and I think that you have enough monster removal already with the Levia Dragon and everything else.

Creature Swap also isn't that good with everyone using Scapegoat these days...so

- Creature Swap
+ Abyss Soldier

Just my two cents. Good luck with your deck though. 9/10

Thanks for the rf's guys:
The reason why I have Creature Swap in Here is so that i can swap one of my Mother Grizzlies or my Sangan for one of my opponnent's monsters then attack it and still get it's effect (For added swarm) it works pretty well though. As for the Abyss Soldiers, I can't get my hands on it so I can't put it in right now, but i will continue to look for it.
Thanks again :) Anyone else?
