New dark elixir troop. Similar to wizard.

I have an idea about a new dark elixir troop called the mirage.
It will have a starting cost of 5k of dark elixir to 10k maxed.
It will have a starting damage of 0 (doesn't attack) .
This new troops skill is a mirage.
The troop creates a distraction by using the mirage.
The troop will create a mirage somewhere in a free space on the map using the troops which are in a 5 (starting) - 10 (maxed) tile range.
The mirage will last 10 secs (starting) - 30 secs (maxed) .
It will be 25 or 30 space in camps.
There will be 5 levels for this troop.
It will look like a wizard but bright red in colour.
The troops in the mirage will be able to do slight damage. 8 times weaker than normal troops.
The troops in the mirage won't die.
If the mirage troop dies then the mirage will fade away.
Please comment on whether you think this is a good idea.
Thanks.
