When we play clan battles,
① put your town hall inside walls to protect it against opponents!!!
you can edit your base on the map of clan battle, and the base on the map has nothing to do with your " practical" base!

② When you attack opponent's base, you can ask for whatever troops you want!!
so write concrete name of the troops you want when you attack.

③ Only leader and sub leaders fill your base with troops for protections.
Write concrete name of the troops on the base of the map.

④ After clan battles start, you must attack opponents who have similar rankings with you.
For example, when your ranking is 15th in our clan, you must attack opponents from 5th to 25th.
However, after 18hours has past, you can attack any opponents.

I'm sorry for my poor English, if you have questions, feel free to ask me.
