Pretty much i've written you a review and modified your deck step by step twice now... and accidentally hit delete and moved back a page on the browser, thus losing all the things i've written for you.
Sorry that you can't see my process, but i'll do it as quickly as possible.
I initially cut the deck back to 40 cards, and realized, Deep Diver could be perfect for this deck, especially since you already have Mother Grizzly.
So i focused on allowing you to have the best access to A Legendary Ocean as possible, and still tried to retain the shape of your original deck.
Kept the Deep Sea Diva synchro engine you had.
Added staple spells and traps.

Pretty much... you're looking to get a hold of A legendary Ocean early in the game.
I'll explain combos. ">" is used to pretty much say "effect used to get"
such as with
Mother Grizzly > Deep Diver
I'm saying after mother grizzly dies, special summon deep diver

from now on, it's assumed that if you don't have Deep Diver at the start of the combos, and you have Mother Grizzly that you make that play to lead into the plays described.

ok so...

Mother Grizzly > Deep Diver > Warrior of Atlantis > A Legendary Ocean
that's easy access to Ocean.
that makes a set Mother Grizzly your most favorable opening play if you don't already have a Legendary Ocean.
When you have A Legendary Ocean, and you're not in advantage

Deep Diver > Giga Gagagigo

to run over your opponent if possible
He's your best no sacrifice beat stick, abuse him.

Deep Diver > Codarus

One of the best plays when you're holding on by a thread, and need a problem solver.

Deep Diver is your toolbox engine, use him and abuse him.
Pot of Avarice and Salvage are your friend with him.

Hope you like my advice.
I tried to keep the foundation of your deck in tact, and simply add onto it, I hope you find the changes adequate.
