New Dark Elixir Troop: Ghost

Hello, my IGN is TreeHuggers and I have an idea regarding a new type of troop.

The Ghost

Now, i'm sure this has been suggested before and I do not claim ownership over the generalised idea of this troop being added to the game, however I do believe I have some interesting ideas regarding the mechanics of the unit. Obviously, bare in mind that these figures would be a rough estimate.

Movement Speed: 12
Housing Space: 8
Targets: Ground
Favourite target: Any
Damage Type: Area Splash

Mechanics

Slow-Moving Unit, Green-ish-Purple hued mist attack; must be quite close to target, is not a constant stream of mist, it fires in bursts, the speed of which is up for interpretation: i.e. once per two seconds.
Every 8 seconds, the unit vanishes and re-appears 3-4 seconds later, in a slightly different position (if the unit was moving beforehand), obviously not far away at all. Alongside this, it can move through walls as if they aren't there (which is why I chose to make this unit's favourite target "Any")

Level 1

Appearance: Slightly Ambiguous on this matter, I was thinking along the lines of, translucent white, somewhat cartoon-like, ghost with glowing eyes of a certain colour: perhaps purple/green to begin?

Health Points: 1200
Damage Per Second: 70
Training Cost: 150 Dark Elixir
Training Time: (Unresolved)

Level 2

Appearance: Same as Level 1.

Health Points: 1340
Damage Per Second: 80
Training Cost: 160 Dark Elixir
Training Time: (Unresolved)

Level 3

Appearance: Unit now has chains hanging over 'arms', alongside this, the glow of the eyes is now red. Shape of Unit could be altered by designer also.

Health Points: 1500
Damage Per Second: 90
Training Cost: 175 Dark Elixir
Training Time: (Unresolved)


There is the general idea, along with it some rough guidelines for the stats of the Unit. I hope you like the idea; constructive criticism is appreciated.
