is this a good e hero deck and what can i do to improve it?

Decide ahead of time if you want a fusion based build, or a City deck. Those are the only viable routes for E-Heroes.

All E-Heroes are NOT created equally, remember that when you decide to build a deck. Variety is not the heroes best friend.

I never really did like the E - Heroes too much. But I do know that most of their spells and traps could be replaced by some other more useful cards. For Example replace Hero Barrier with magic cylinder or scrap-Iron Scarecrow. I also think that you should definitely add at least one more Polymerization and another Miracle fusion if possible. Also, remove the winged kuribohs and the Transcendent wings, they're too slow. E Hero Knospe is also a card that should be replaced for it's not very good. Some Fusion Substitutes would also be very helpful in this deck, especially King of the Swamp. I also think that you should try to incorporate some Evil Heroes in if that is possible, I like them much more.

I would add to your Fusion Deck: Elemental Hero Electrum, since you have Bubbleman, Burstinatrix, Clayman, and Avian.

I would get rid of Winged Kuriboh 'cause nearly everyone knows that if you play with a E-H Deck, Winged Kuriboh is bound to show up.

Also add some of the Evil Heroes, they're more better with their effects, and include Super Polymerization.

Include, 5th Hope, a spell card that allows you to choose 5 Elemental Heroes from your Graveyard, put them in your Deck, then Draw 2 cards, but if you have no cards on the field and no cards in your hand, Draw 3 cards!

Stupidity

first of all re-fusion won't work on e-heros if you read the card text it says it sannot be special summoned except for fusion summon. add future fusion it is a good combo with miracle fusion. and more polyperization would be good.

you should add neo spacians like grand mole. also you should add e hero neos. he is good. also add d hero defender. he's good in defense. take out reload for magical mallet. you chose which cards stay in your hand. also would be a good card would be hero counter. its just like hero emerges except you can destroy a monster if your opponent choses a e hero
