Elemental HERO Neos X
lv 7 LIGHT
Warrior/Effect
(This card is always treated as "Elemental HERO Neos".)
You can Special Summon this card from your hand to a zone a Link Monster points to. You can only Special Summon "Elemental HERO Neos X" this way once per turn. When this card is Normal or Special Summoned: add 1 "Polymerization" or "Neos Fusion" from your Deck or GY to your hand. You can only activate this effect of "Elemental HERO Neos X" once per turn. When a "Neo-Spacian" and/or "HERO" monster(s) you control would be destroyed by battle, card effect or returned to the Deck by its own effect, you can send this card from your GY to the bottom of your deck instead.
ATK/2500 DEF/2000

So Elemental HERO Neos X is a retrained Neos which actually acts as Neos at all times where it can be Special Summoned to a zone a Link Monster points to where the X in its name acts as word play in relation to the Xtra HERO Link Monsters. This card helps both HERO and Neos Decks as it on summon can search Polymerization and Neos Fusion while also being able to recycle said cards. Finally like Neos Fusion this card can also protect your HERO monsters to a level the same as Neos Fusion where the card itself returns to the bottom of your deck instead of being shuffled in.

In HERO's this is a ideal card that can help ladder up links, set up Fusions and provide some additional protection for your HERO monsters.

I don't support this. Harpie Lady clause + amazing effect makes it outclass the original Neos almost right away except for the Normal support it won't get, but as a Level 7 it barely got any decent Normal support anyway, I can only think of Summoner's Art. The effects makes it look quite abusive too: built-in way to Special Summon it that is easy to fulfill, and it grabs Neos Fusion, potentially a power card, or just Poly for less restrictive Fusion Summon or just discardable hand advantage. As if that wasn't enough, the last effect is good too, providing protection and self-recycling.

You know, it's funny. I actually made a few cards focused more on Neo-Spacians and NEX, and one of the cards was an Xyz called Elemental HERO X Neos. Not saying you stole the idea or anything, Neos X has a way different effect than X Neos, just a funny coincidence that's all.

Good card. Would use it if I cared about Links.

The summoning condition of this card feels out of place given the archetype it's supposed to support. Neo-Spacians don't have any archetypal link monsters, so you would have to rely on generic Link monsters ( such as Isolde ) or HERO Link monsters ( such as Wonder Driver ) to summon him. Searching Polymerization is also not the best since the archetype it's supposed to support is based around contact fusion rather than fusion by polymerization ( even if Brave Neos and Rainbow Neos can be summoned by polymerization, most of the archetype is based around contact fusion ). It probably should search Miracle Contact and Neos Fusion instead of Polymerization and Neos Fusion IMO. 

A Special Summon condition more along the lines of "You can reveal 1 "Neo-Spacian" Monster in your hand to Special Summon this card from your hand HOPT" would probably be better, since it would give better utility to Neo-Spacians in your hand. 

Also, on the naming, it should be "This card's name becomes "Elemental HERO Neos" while in the hand, on the field, and in the GY" rather than always, since it would have the Harpies ruling ( as mentioned by Darj ) where you can only have a total of 3 cards whose original names are always 1 name, even if they are 2 separate cards.
