Neos Heros

Well I got an issue on building a deck revolving around Elemental hero neos and his friends the neo-spacians but the issue i come to face is trying to combine them with other heroes. i made two versions that are my best ones so far
 
Neos v6

Neo-spacian v4

I know they aren't the best but i need help on trying to find cards that help the deck flow and have synergy

it's really nice to see a player who's trying to build a deck like this "E.heroes with neo-specians" 
well first i think this deck won't be good if you dueled a single duel " u need to put a side deck and benefit them btween match rounds" it might be stronger tho
back to the deck build itself 
hmmm... hmmm.... 
* a deck like this must contains 40 Main cards deck "in my opinion" so u don't need to put more than this amount
* mirror force is useless these days .. just put 1 mf , 1 DP and 1 bottomless trap hole (well u can't put more that one XDDD) 
* put 3 of that field card "neo specian" or kinda of that ... replacing them by clearing 2 terraforming. 
for da 2nd deck 
it's good in my opinion "regardless u've 2 mirror force" in my sight it's perfect .. u need to try it agains other duelists and make a crucial changes

that was just my opinion
u r awesome bro

thx though just 40 cards have been what I'm trying to aim at but sometimes i don't know what spells to use or that i might need a little more room to use them so I get a bit over 4o. never 50 though. I tried 60 card build and well it was dead draw central at times

Don't go over 44 cards.

why?

The deck's consistensy will go down then, up to 44 cards can be okay, but no more.

try thinning down to 40 and keeping your best cards,i understand u wanna use all of em but still 44 might give you bad hands etc and since you dont have that much draw power it could be a problem

see I understand that in the matter just, it's hard to make the combos you need with short card amount. So far I got this version
