The Mimic

This idea just came to me from the cartoon series, pokemon, where the Pokemon mimic, can become any other Pokemon and get it's power ! Now this is where my idea struck me up !
A troop taking 20 housing space. Can turn into any troop which you have in your army camp while u go on a attack. The catch is, u drop the troop u want it to be, just before u drop the mimic.. thus if u drop a golem, and Dn the mimic, this mimic becomes a golem for u. It's an interesting troop as it won't have much Hotpoints or attack per second while it's a mimic, but gets all the power n other stuffs of the troop u want it to become. We gotta be careful. But it surely can become an incredible troop if you can trust me :) but rest is all on supercell.
Drop down ur ideas and queries here :) will be happy to answer to you guys.
Clash on folks!
