Dealing with enemy Clan castle Troops

Hi Guys I dont know how many of you know this but just to make sure it is thrown out there. when attacking an enemy that has troops coming out of clan castle i found out that the best way to deal with them is to finish them off with 1 lightning spell. it will instantly kill any troops except Drags And pekka in the village. If they do have those best solution is to just use archers. they effect very well.

Yeah I noticed it as well. The easiest way especially when they are lvl6 archers.
