i dont rly know the deck but try to get it to 40 cards deck that deosnt have much draw power need to not have too much cards and and dimentional prison are always better then scarecrow
i would help more if i would knew the deck more but gl whit it

You have way too many cards :/. Just being honest. With so many cards it highly lessens the chance of getting your combos together....yet in all of those cards you're missing really great staples like Dark Hole and Solemn Warnings. I'll have to look up each individual Roid to help you more, but I doubt you'll need that many. Drop the last 6 traps, some copies of Roids, a Cyber Dragon, the proto-cybers, polys, kings of the swamp, botomlesses, cylinders, and add Dark Hole, Book Of Moon, Giant Trunade, 2 Solemn Warning, torrential tribute, 2 dimensional prison, and probably 2 Solidarity and another Duality or 2. I don't mean to bg on your deck but it just isn't competitive with so many cards, and the Cyber fusions will slow you down...or you could go with the Cyber Fusions and drop the Roids. Try if at all possible to make 40 cards. The most you should ever have is 42, and that's usually in a Lightsworn build that mills a lot

Yeah i can see where you are both going with this, and i agree but wouldn't it be risky running 2 solidarities while King of the Swamp is there since he's an Aqua monster? I actually experimented with the Cybers and found that they "CAN" come in handy but not worth it when i can use VCZ which is a powerful card for this deck when used to summon Jumbo Drill or Stealth Union.

*Edit* Thanks Harper, i made good use of your advice and made a full-on Roid deck. The Solemn Warnings and Torrential Tribute cards really came in handy and i've managed to win more often. Thanks ^^

play fusion sage insted?

No point, Vehicroid Connection Zone is a fusion card for roids but isn't polymerization.

hmmm there all machine no i would play limiter removal

Funny you should say that because if i summon a Super Vehicroid with Vehicroid Connection Zone the Fusion monster cannot be destroyed by spells, traps or effects and its own effects cannot be negated... so Limiter Removal would not destroy them at the end phase

so that would be a nice add and i would try unkown syncron hes a machine tuner wich would give you a way to syncro he deos like cyber dragon but u can only use him once and idk if your monsters atk are low but why not sangan?

I actually hate Synchros... just a personal opinion. I'm old-school and grew up with fusions.

okay i understand that but you know if u wanna become good and win tournys you gotta evolve whit that game xP but eh im not here to tell you how to play just help

Glad I could help! The deck looks quite a bit better now. Yeah synchros are nice but in this kind of deck it isn't the focus anyways so it doesn't matter much whether or not you use them. However, since you have many slots available in your extra, try putting in some staple generic synchros. You may not have a tuner, but your opponent surely will so if the only way to get out of a situation is Reborning a tuner to synchro, you'll he glad you added them. Since this is DN and you don't have to worry about spending money on synchros either, why not? Another thing to put in your extra is 1-2 Chimeratech Fortress Dragon. In a match, chances are people will side Cyber Dragon to Chimeratech your machines, so you can Chimeratech them instead or Reborn their Cyber Dragon and fuse if you need something bigger. And you will often find the opponent do something dumb like special cyber, normal summon a machine. Fuse fro their field to get a monster with 2000 atk: a +3 for you. Also, though it was a good idea to get rid of the Cyber fusions, Cyber Dragon by himself is a good card. He's big, a machine so you don't break Solidarity, a free special summon, an he baits out Bth and Warning. If it turns out you don't need 3 copies of certain Roids, drop a few for 2 Cyber Dragon. And if not, side him. And finally, I would find room for Monster reborn, 2 mystical space typoon, solemn Judgement, and a limiter removal. Limiter is otk material, and mst really helps clear annoying backrow. It's pretty much a staple these days. Solemn is Solemn...negate anything, just be careful when u use it. I think you just forgot about Reborn haha, it's great. I would say:
-2 cylinder (good card though)
-2 botomless (you need backrow hate over more backrow)
+1 reborn
+1 limiter
+2 mystical space typhoon
-1 roid monster of your choice
+1 judgment
+some synchros like stardust, scrap dragon, brionac, brd, catastor, etc
+2 chimeratech fortress dragon
