A New Castle - Traitors Prison

This is my debut posting in any forum ever...

#1. In this new prison we fill it by luring out and defeating clan castle troops.
#2. The newly defeated inmates go into a pool called "Rehabilitation Ward".
From the "Rehab Ward" troops are selected or deleted to make room for more new inmates.
#3. The selected rehab troops go into "Work Furlough" program.
#4. Work Furlough is just a pretty name for war prisoners turned into fighting slaves.

All of this happens in a pop-up window that is barracks-like on top displaying the newly incarcerated inmates and clan castle-like on the bottom displaying deployable slave troops on the bottom.
The Traitors Prison is upgradeable just like the clan castle.
The cool benefit of the Traitors Prison is it allows you use troops you encounter in multi-player battle but may not have access to because your clan mates don't have it or are unwilling to share. Since the troop was defeated in battle you are allowed the one time use of them then they are gone.
This new feature promotes multplayer battles and another item to spend gold on.

Whaddya think?
