Unlike most Fusion Monsters, which must be Fusion Summoned, "Neos" Fusion Monsters are instead Summoned via Contact Fusion, which only requires the Fusion Materials to be on the field. However, the "Neos" Fusion Monsters also have an effect that returns themselves from the field to the Extra Deck during the End Phase. To avoid this, the Field Spell Card "Neo Space" allows the Fusion Monsters to stay on the field as long as "Neo Space" does, and the Equip Spell "Instant Neo Space" allows the equipped Fusion Monster to stay on the field (as well as allowing the Special Summon of "Elemental HERO Neos" when the equipped monster leaves the field). The Monster Card, "G.B. Hunter", can also prevent the final effect of the "Neos" Fusion Monsters from applying, but will also stop further Contact Fusions. There are the 6 primary "Neos" Fusion Monsters, 3 Summoned by Triple Contact Fusions ("Magma", "Storm" and "Chaos"), and 1 requiring a Fusion Material Summoned with "NEX" ("Marine"), for a total of 10.
A good card to include is "Elemental HERO Prisma". It can send a "Neos" monster to your Graveyard and have its own name treated as "Elemental HERO Neos". You can then use it for the Summon of a "Neo-Spacian Fusion", or use cards like "Wrath of Neos" on it.
"Miracle Contact" is the Neo-Spacians' best card, as it can access your hand, your side of the field, or your Graveyard for the monsters you need to Special Summon your "Neos" Fusion Monsters (however, any monster Summoned by "Miracle Contact" do not count as having been properly summoned, so they cannot be Special Summoned again through other cards or effects). "Contact Out" is especially useful in avoiding card effects that force your monsters to leave the field (such as those of your own "Neos" monsters), or can allow for multiple attacks if your opponent controls 1 or no monsters.
"Elemental HERO Neos Alius" is a Gemini monster whose effect allows him to be treated as if his name was "Elemental HERO Neos." This is very useful in a "Neo-Spacian" Deck, as it gives you the option of having more than three "Neos" to use in Contact Fusion. It is also a Level 4 monster with 1900 ATK. Given that "Neos Alius" is a Gemini monster, he can be supported by cards like "Supervise" and "Gemini Spark". One popular strategy is to stick exclusively to the most useful "Neo-Spacians": "Dark Panther", "Grand Mole", "Air Hummingbird" and "Flare Scarab".
