It's a good thing we saw that flashback of Jaden drawing these cards as a child, because that explains why they have as many issues as they do.
When playing a Neos deck, be prepared to activate
Neos Fusion, having 7 options to choose from, then defaulting to 2 of them.
Rainbow Neos is an incredibly versatile card to help even the playing field with your opponent. You'll want to go into him if your opponent has a field of monsters that you're not gonna be able to deal with, or a lot of backrow. If neither are the case, shuffling back their GY is costless and never hurts.
Neos Kluger can swing for massive amounts of damage and deal a lot of burn. If you equip Kluger with
Favorite HERO, you'll have a 6000 ATK beat-stick that burns your opponent for large amounts of damage. Since his burn effect is not OPT, you can use the second attack with Favorite HERO to hit in a second time to close the game. Favorite HERO is also the reason why we run a single copy of Neo Space.
Sadly the other Neos Fusions aren't in the same league. Starting with the two-piece fusions,
Air Neos used to be the biggest beat-stick, but is more often than not outclassed by Kluger.
Dark Neos can negate monster effects, but hits the field after most of the ones you'd want to negate are taken care of.
Grand Neos spins a monster back, but so does Rainbow Neos.
Aqua Neos is probably the best of these with his hand ripping effect, but is held back by it being random.
Brave Neos searches for either Miracle Contact or Neos Fusion when he destroys a monster, which is a decent effect but is too slow.
The triple/quad contact fusions are pretty great, but are a pain to summon.
Cosmo Neos drains all your resources, but if you have lethal it ensures that nothing will stop you.
Nebula Neos gives you some much needed draw power and negation.
Storm Neos clears the backrow... (so does Rainbow Neos lol). All of these cards clear the field when they go home to visit grandma during the end phase. This is usually not helpful during your end phase, and while it can be good during your opponents end phase with Neos Fusion's GY effect, you have to think about what you are possibly gonna do during your next turn after losing everything. Just pray you don't draw into any of the Neo Spacian's you shuffled back.
Fusion Dispatch summons any of your Neo Spacians/Neos/Yubel from the Deck and helps a lot for contact fusing the larger monsters.
NEXT is potentially a great card, but Neo Spacians and Neos rarely hang out in the GY.
Miracle Contact keeps this deck somewhat playable. I wish
Convert Contact didn't have the "control no monsters" restriction, but is otherwise your only draw power.
Forbidden Droplet/
Triple Tactics Talent/
Pankratops are good for going 2nd (BTW good luck if you have to go first, you're gonna need it).
Don't think too hard about the Link monsters.
Verte Anaconda is basically the only one that matters. I honestly couldn't think of what else to put.
Feel free to add in
Neos Wiseman if you really want to float into him with Kluger, personally I didn't bother considering the massive amount of bricks Neos has to put up with already. While you're at it, go ahead and swap out the spare Grand Mole's, Dark Panther's, and link monsters for a copy of Flare Scarab, Glow Moss, and their fusions you absolute madman.
Let me know what you think! This is by no means a definitive deck list.
