Parallax Engineer

Artifact Creature
When Parallax Engineer comes into play, remove all artifacts you control other than Parallax Construct from the game
When Parallax Engineer leaves play, return to play under their owners' control all cards removed from the game with Parallax Engineer.
Fading 3
(This artifact comes into play with three fade counters on it. At the beginning of your upkeep, remove a fade counter from it. If you can't, sacrifice it.)
4/4
The demon machine set to guard the great engine of the gods.The card is basically designed to be an answer to Recall/Rebuild for Shops deck, but also create interesting play routes of it's own.
The way it works to help storm decks is basically play this and remove all your artifacts from play. Once you do, you can start playing more artifacts again. So if you went turn 1 Sphere of Resistance, and turn 2 Parallax Engine followed by another Sphere of Resistance. A storm deck could not simply bounce your Artifacts and then go off because upon being removed from play the removed artifact would return and again inhibit with the other Sphere of Resistance.
However it can also be a high risk play. Chaining a Chain of Vapor/Recall/Rebuild to it coming into play triggers the leave play effect before the come into play effect, which basically means all the artifacts are removed with no way of being returned.
Additionally, the ability gives you another play option and the ability to play artifacts at (sort of) instant speed. So you could go for turn 1 Parallax Wave, then play turn 2 Sphere of Resistance and then remove another Sphere of Resistance with Parallax Wave's activated effect.
The fading counter is there because "Parallax" is associated with them. Incidentally it ended up being a good cost for the ability.
EDIT: Also considering a different ability....
Fading X
(This artifact comes into play with X Fading counters on it where X is the number of artifacts you control. At the beginning of your upkeep, remove a fade counter from it. If you can't, sacrifice it.)
Remove

Fading counters from Parallax Engine,

: Remove an artifact card with a cost X or less in your hand from the game.
EDIT:
Fixed it so that it doesn't loop with itself or other cards with the same name.
EDIT:
Removed the ability. Now that it is a creature it seems to be a bit excessive. I also increased the mana cost to justify it's size. it's fairly useless turn 1 anyways.
