Forum:Elemental Hero Deck Help?

Hey there, i just was wondering if i could have some tips on how to make my E-Hero Deck a bit more competitive. It hasnt been doing terribly, but i feel like it could do better. Anyways:

Monsters: Elemental Hero Neos Elemental Hero Avian Elemental Hero Burstinatrix Elemental Hero Sparkman Elemental Hero Clayman Elemental Hero Bubbleman Elemental Hero Wildheart Elemental Hero Necroshade Elemental Hero Captain Gold Elemental Hero Stratos Elemental Hero Ocean Elemental Hero Bladedge King of the Swamp x2 Neo-Spacian Grand Mole

Spells: Skyscraper x2 Skyscraper 2-Hero City Polymerization x2 O-Oversoul x2 E-Emergency Call x2 Super Polymerization Fifth Hope De-Fusion Re-Fusion MST Miracle Fusion x2 Fusion Recovery

Traps: Mirror Force Hero Signal Justi-Break Threatening Roar x3 Hero Counterattack Magic Cylinder

So please tell me some cards that would make it stronger to add, or that it would help to remove. I believe i have all the elemental hero monsters, and most of the support as well. Thanks :D
