I'm trying to make an e-hero deck and I wanted to know whats the best cards to support them. The e-heros are normal monsters and I was wondering cards help normal low level monsters

If you mean just the basic E. Hero's WITHOUT the fusions, then....

Sword of the Soul-Eater (only works on Featherman or Burst Lady)
Non-Spellcasting Area
Spirit Barrier
Astral Barrier
Covering Fire
Rush Recklessly
Hero Signal
The A. Forces
Reinforcement of the Army
Last Will (works for all, but Sparkman)
The Warrior Returning Alive
Creature Swap
Axe of Despair
United We Stand
Mage Power
Command Knight

are pretty good one's to use with them that are in english. In Cybernetic Revolution/CRV, there's also

CRV-JP016
Cybernetic Magician
Light/Spellcaster/6/2400/1000
Discard a card from your hand. Until the end of turn, the attack strength of a face-up monster on the field would become 2000.

CRV-JP047
Spark Gun
Magic - Equipment
This card can only be equipped on [E-Hero Sparkman]. During your Main Phase, you may choose to change the mode of a face-up monster on the field. After this effect is use 3 times, destroy this card.

CRV-JP048
Skyscraper
Magic - Field
When monsters with "E-Hero" in its name attack, if the attack strength of the attacking monster is lower than the attack strength of the attacking target monster, the attack strength of the attacking monster would be increase by 1000 until the end of turn.


However, some cards aren't listed cause I'm ASSUMING you only mean Featherman, Burst Lady, Sparkman and Clayman and not the fusions or anything.
