New troop

Hey guys, I just though of a new idea so I decided to post to see if other people agree with me. I though of a new troop. This troop would be like a ghost. This troop couls be able to pass through the wall and to attack he would like go over the defense(because he would only attack the defence like the giants) and drain his life points until he destroy it and he like stole the life so he regaine the same amount of life that he hade take from the defence. Plus, he could do the same thing to the clan castle troops or the heros. This guy would cost 600dark elixir and be able in a 5level of the dark barrack or cost 45000 elixir and be able in the 11level of the barrack. He would have 3500 life points but he could go to a maximum of 5000 if he drain some life point from the defence and do 500 damage per seconde( I didn't want to put like 3000 damage because he regaine some life and by shot of 3000 it would be pretty easy). But those upgrade of the barrack would be able at town hall level 10 or 9. He would have 4 upgrade and each time his maximum life points and initial life points would upgrade by 50 and his attack same +50each time. This new guy would be not clear like you won't be able too see through him but he would be like a grey white and at each upgrade he could beacome darker and darker until he become black. He would have the aparence of a normal ghost but when he drain some energy he become bigger and bigger and become like some diamond, but when he destroy the defence he become normal. Thanks for reading and I hope you take my idea in the next update of CoC.

Umm...... Ok?
