New Troop idea: Dark Giant (If you find a better name use that one)

Troop Name: Dark Giant
Requires: 450 Dark Elixir
Training Time: 1 hour
Movement Speed: 5-10 (Your choice of speed)
Targets: Ground
Preferred Target: Any
Damage Per Second: Your Choice
Damage Per Hit: Your choice
Hit Points: 4000-5000

The name 'Dark Giant' was the only name I could come up with, but it is basically a Giant heap of Dark Elixir (Or a giant that has consumed Dark Elixir but didnt have the same effect of Barbarian King or Archer Queen). When It comes across a dead Troop (gravestone) it sucks it up and its health increases by 200 (increase or decrease). Due to it consuming so much Dark Elixir it has become slower, though it is good for soaking up Hits, like the original Giant.
It is especially good if you send in troops before sending in the Dark Giant, with the troops dying and the Dark Giant gianing health from the Gravestones, it can easily clear through an amount of Buildings.

I only thought of this briefly, I might have skipped over some additional info to think about.

Before I can give good advice, saying 'your choice' isn't final enough

Also, this is pretty much a golem except with more HP and with the ability thing it makes it a bit OP

Yea, ill edit it later. Ill have to think about the attack and levels stuff later. Ill work on it. Thanks for giving me some advice on it.
