i am not any good at this deck and idk how it work , but from what i see u miss some main monsters and put them at 1 and put usless one and at the end this deck can't be competitve as much u think

Well, a Roid deck just can't be competitive nowdays, but then, just because is a roid deck doens't means that you have to run EVERY ROID on it, some cards to add consistency would be good too. Draining shield is kinda pointless, getting some LP will give you less advantage than banishing his monster with Dimensional Prison or Bottomless Hole, I also miss the Solemns there. Mind Control is for what? I don't get it, you only run 1 XYZ that is made with 3 level 4's, and is not good at all.

Maybe there are some reasons why the deck is not working, also most of your fusions have a too specific summoning condition with poly, I can't really see it being able to summon Barbaroid unless it is a miracle draw.

First off, the main problem is roids are a bad deck - their effects don't really help each other out so they lack cohesion. Second, you seem to be suffering from the "Archetype Syndrome," in which you add clearly obsolete and outclassed cards for the sole reason that they have *enter archetype name here* written somewhere on the card text. I suggest trimming the deck down to focus on a few roid monsters first. Right now it seems like you tried to mash every single roid card in existence in a deck and hoped it worked, which it didn't as you've found out.

i ran a powerful style of roids in yo3 they can be a vbery good deck if known how to use.
most of what they say is right u need to use more xyz and warrior archtype to use ufo roid fighter cause right now its not even possible to summon in that deck. consider mixing roid with ehero or other strong warrior type monsters. here are cards u need to add for it to work

2x gorz
2x ufo roid
2x powerbond
2x cyberdragon
1x chimerath overdragon
1x chimeratch fortress

the warriors dnt really matter in this deck but u should consider taking out alot of the roids in this deck and adding in warriors. make only half of your monsters roid and the rest warrior type monsters
