Attacking while being attacked
Just a thought but when you see your village being attacked it would be cool to be able to influence the outcome or throw a curveball to the attacker in a small way. For instance if you have a lightning or poison spell you could drop that on the enemy troops. Or if you have a rage or heal spell you could drop that on your cc troops.
Also an invisibility spell would be cool for attacks. I thing only for individual troops like the king or queen though.
Just some thoughts
