New spell: Betrayal

This would have to be like a holiday special spell or something but, what if you're attacking a base and the enemy's troops came out to protect the base and you throw a spell on them which has then attack their own base for 5-10 seconds. Yes that sounds insane but it would cost a lot such as 40000-60000 elixir. It would give a twist on the game but it would be fun to watch.

Way too OP. It would make people put weak or no troops at all in their clan castle. How would you feel if someone donated you a dragon for defense and someone just drops a spell on it, using no skill at all?
