This is the Neos Deck I am gonna try when STON comes out. I can tell it probably won't run good so I can take constructive critisim.

Monsters 20

3 Elemental Hero Neos
1 Elemental Hero Wildheart
1 Elemental Hero Necroshade
1 Elemental Hero Stratos
2 Neo-Spacian Flare Scarab
2 Neo-Spacian Dark Panther
2 Neo-Spacian Aqua Dolphin
2 Neo-Spacian Air Hummingbird
1 Neo-Spacian Grand Mole
2 Neo-Spacian Glow Moss

1 Pot of Avarice
1 Premature Burial
1 Neos Force

Traps 6

2 Sakuretsu Armor
1 Mirror Force
1 Ring of Destruction
1 Call of the Haunted
1 Torrential Tribute

Total Cards 43

Fusion Monsters

2 Elemental Hero Glow Neos
2 Elemental Hero Dark Neos
2 Elemental Hero Flare Neos
2 Elemental Hero Air Neos
2 Elemental Hero Aqua Neos
2 Elemental Hero Grand Neos
2 Elemental Hero Necroid Shaman x1

3 Neo-Spacian Ground Moss = Neo-Spacian Grand Mole and its limited to one.
3 Elemental Hero Ground Neos = Elemental Hero Grand Neos =P

deck looks ok, I'd have to actually see it in action though.

The Neos Fusions can't be summoned via Fusion Summon, so King of the Swap and Future Fusion are pointless. And running three of every Neo Spacian isn't the wisest of things to do.

Try this. I ran something like this a while ago, and it was pretty consistent. The Neos Strategy happened more often than expected, with the Fusion strategy as a nice backup.

Aqua Dolphin's there for discarding Necroshade for Neos, or discarding Neos or Jinzo to bring him back. Air Hummingbird makes for nice life gain, and combos with a surprise Lily tht your opponent might now expect. Grand Mole's awesome. Nuff said.

You decide between Ancient Rule and Fake Hero. Fake Hero = Airman abuse, while Rule nets you a 2500 beater. Hope this helps.
