jail houses to make revenge possible.

Revenge is impossible on attacks from superior villages. What if the attacking village lost a portion of their army for a short period of time. The attacked village could use the troops for a revenge attack or loose them over time or just release them. The jail could cost say 2000 gems and would have to be reloaded with elixer every time it was used. the jail would help level the field by making revenge possible as well as making the attacking village consider attacking a equal opponent were the jail would not have the jail ability. The attacking village would get it's lost troops back in 24 hours.
