The corruptor dark troop

Ok so we should all know dark troops are special because of their unique abilities no other troop has. Well i have come up with a new dark troop with a skill that literally will turn the table in battle. Say hello to the corruptor!!

The corruptor is a creature that is made completely out of dark elixir. He looks like a werewolf and is black with red eyes. He has smoke rolling off his back because he is completely made of a dark elixir fog.

I am sorry to not say exact numbers on his cost and space and so on. I'm not quite experienced in dark elixir and high lvl troops to know whats appropriate for this troop. He will cost more DE than witches and has a housing space of about 20. It also has about the hp of a maxed giant. This creature does not actually attack himself, but instead jumps over walls to the nearest defence, where he disappears into it, corrupting the defence. The defence building turns gray and has black smoke coming off of it while it is corrupted. The corrupted defence then turns on the other defences (or misc. buildings if there are none) and attacks them until the corruption time wears off or it is destroyed. Corruptors corrupt defences for 15 seconds before it wears off. Multiple corruptor a can enter a single defence, lengthening time. If the corrupted defence is destroyed, so is the corruptor(s). This creature will be the one that all shall fear to enter their base!!!
I hope this idea is considered for DE troops. I am once again sorry for low amounts of specific costs because i am not well experienced in dark elixir. I hope someone more experienced comes with a good cost for this troop (which must be high because he is VERY powerful) thank you for reading.
