Welcome to Gaia! ::

I am in the process of writing a Yu-Gi-Oh! fanfiction. Of course I know one of the main points of Yu-Gi-Oh! is the decks and the duels. However, I am not that great at building decks. I request some help in the building of the decks. I am building the rough drafts by myself but I want more opinions and Ideas to refine the decks and make them function at their best. The decks don't have to be the best decks ever, they should be fairly good and function well. Most of the duels are going to be competitive in one way or another. So here is the first deck. A genex deck that is mainly based around summoning the genex synchro monsters but partially based upon summoning the other powerful monsters to beat down the opponent.



Monster Cards:

-Genex Controller x3
-Ancient Gear Golem x1
-Genex Ally Bellflame x1
-Genex Ally Birdman x1
-Genex Ally Changer x2
-Genex Ally Chemistrer x2
-Genex Ally Duradark x1
-Genex Ally Powercell x1
-Genex Ally Reliever x1
-Genex Ally Remote x3
-Genex Army x1
-Genex Blastfan x1
-Genex Furnace x2
-Genex Gaia x1
-Genex Neutron x2
-Genex Recycled x1
-Genex Searcher x 2
-Genex Solar x2
-Genex Spare x2
-Genex Turbine x1
-Genex Undine x1
-Genex Worker x2
-R-Genex Accelerator x1
-R-Genex Ultimum x1

Spell Cards:

-De-Synchro x1
-Heavy Storm x1
-Lightning Vortex x1
-Machine Assembly Line x1
-Mystical Space Typhoon x1
-Reload x1
-Rush Recklessly x1
-Shrink x1

Trap Cards:

-Call of the Haunted x1
-Draining Shield x1
-Dust Tornado x2
-Negate Attack x1
-Widespread Ruin x1

So that's the deck, opinions are welcome. And I don't mind if criticism.

I see where you're coming from with using only a few genex synchros and focus on them. However the only thing that matters for genex synchro monsters tends to be Genex controller as the tuner and any monster with a specific attribute. For example Thermal Genex you need Genex tuner and 1 or more non-tuner fire monster. The reason that this isn't that troublesome is that Genex Ally Changer and Genex Ally Chemistrer both have effects to change attributes making it much easier to summon a multitude of genex synchros.
