[YGO]: Rate/Improve my HERO deck

I am currently running an Elemental Hero deck focusing around Absolute Zero and Acid's effects. So far results from testing the deck have been good but not great. That's where you guys come in. Please help me improve this deck and make it better.

Quick sidenote: I don't run Neos Alius in this deck and don't plan to. This also means that no Gemini Sparks are included in this deck. Keep that in mind when reviewing this deck. Thanks!

You look like you know what you're doing, so I'm just here to offer the following pieces of advice:

It's harder to run a monster-light deck without the recursive advantage that Neos Alius offers (with Hero Blast and Gemini Spark), and Ocean is not really strong enough as a beatstick. You might want to run different / more Heroes and / or other monsters to help remedy this. I can see Mask Change leading to some supremely glorious dead draws. Also, Polymerization is pretty bad (but you knew this already, play A Hero Lives instead?) - I know you're running a King of the Swamp engine thing but yeaaaaah no.

Okay, so I've updated my decklist taking into consideration the above suggestions. I've also added a few cards to the deck.

3 Bubbleman
3 Neos Alius (I really didn't want to run him but...)
2 Ocean (I had to cut him and the two King of the Swamp for Alius)
1 Stratos
1 Evocator Chevalier (another Gemini Spark target and Fire attribute for Nova Master)
1 Gorz

1 A Hero Lives
1 Book of Moon
1 Dark Hole
2 E - Call
2 Fusion Gate
2 Gemini Spark
1 Heavy Storm
2 Mask Change
2 Miracle Fusion
1 Monster Reborn
2 MST
2 Parallet World Fusion
1 RotA

1 Bottomless
2 Compulsory Evac Device
2 Dimensional Prison
1 Hero Blast
1 Solemn Judgment
2 Solemn Warning

The Extra deck is the same (excluding 11 Acid for 1 The Shining)

I probably wouldn't run too many Ocean or Chevalier, and Card Car D can be helpful in their place. Cards like Pot of Duality, the third Miracle Fusion, the third Gemini Spark, another copy of Hero Blast, another copy of A Hero Lives, copies of Torrential Tribute, and your other copy of Bottomless would all be great additions - try to make your deck more consistently powerful instead of playing powerful-but-limited cards like Mask Change or Parallel World Fusion (though Parallel World Fusion can be the right choice sometimes, Mask Change is usually not).

Well actually it really depends on if you want to play more Alive HERO or Gate / Parallel World. There are merits for both, though I personally prefer Alive HERO.
