Untouched Ocean

This is basically an Umi Deck, Umi being replaced with A Legendary Ocean naturally.
The strategy is to get Ocean, Tornado Wall and preferably also Astral Barrier on the field. This way my monsters can't be touched and nor will my LP take any damage.
My offense if to attack directly, abusing Ocean's effect of reducing WATER monster's star levels with Level Limit and Gravity Bind.

Deck: 40

Monsters: 19
1x Levia-Dragon - Daedalus
3x Warrior of Atlantis
3x Uforoid
3x Mother Grizzly
3x Amphibious Bugroth MK-3
3x Submarineroid
1x Sangan
1x Morphing Jar
1x A Cat of Ill Omen

Spells: 10
3x A Legendary Ocean
1x Salvage
1x My Body as a Shield
1x Level Limit - Area B
1x Limiter Removal
1x Monster Reborn
1x Smashing Ground
1x MST

Traps: 11
2x Tornado Wall
2x Astral Barrier
1x Gravity Bind
1x Bottomless Trap Hole
1x Mirror Force
1x Torrential Tribute
3x Solemn Wishes

I should probably get another Daedalus, but I'm not sure what to throw out. I could maybe mess with 1 Uforoid and Morphing Jar, also thinking of putting in another Cat, since my main strategy is based on the traps. Maybe get Curse of Royal for protection idk..

Well... I don't like some cards in your list. This is what you should change (in my opinion)

Monsters:
- UFOROID x3 (I know it can search for for your machines but it's LV6!!!)
- SANGAN (you don't need it, you have Mother Grizzly x3)

+ LEVIA-DRAGON - DAEDALUS (or maybe MOBIUS THE FROST MONARCH)
+ GIGA GAGAGIGO (it's LV5, but if you have Legendary Ocean...)
+ ABYSS SOLDIER x2 (one of my favorites)

Spells:
- MY BODY AS A SHIELD
- SMASHING GROUND

+ SWORDS OF REVEALING LIGHT
+ LIGHTNING VORTEX

Traps:
- ASTRAL BARRIER (it works only if you have Legendary Ocean and Tornado Wall, one is enough)
- SOLEMN WISHES x2

+ DARK BRIBE x2
+ SOLEMN JUDGMENT

That's all from me...

-x3 UFOroid---- +1 Maiden of the Aqua +1 Mobius, The Frost Monarch +1 Abyssal Soldier
-Sangan----- +1 Abyssal Soldier
-x1 Limiter Removal---- +1 salvage
-x3 Solemn wishes--- +2 Solemn Judgment +1 bottomless trap hole

I really don't like the idea of relying on all those spells and traps to save yourself. Wouldn't a basic Levia-Dragon Nuke deck work better? We'll talk.

Main stratergy on traps....You might want to rethink that, jus imagine..if a jinzo comes into your way..you probbaly would get into some trouble..you should have more levia dragons...and yes the classic levia-dragon all time favourite..in my opinion would work better.
