Fire and Ice? Or the Time relapse. Have a spell that freezes and drops a certain amount of minimal damage. Or the Time relapse. Be able to reverse deployment..BUT NOT the actual game clock. Only inside the small perimeter. Just a thought. Ever seen the movie Looper? Make a troop that can disappear and comeback. Funny thing is once troops are deployed you as a player have no control of the troops. So drop a looper and have no idea where and what he will get into.-Dini
