Some of the importend things is, make a 3 hero! you can only use 2 of them so thats also good for if you upgrade your hero and you still want to be in cw! Also, for new defence's, make that you only can use 36 defence's at a time!
My own suggestion is: a troop bank, members of a clan can take troops there if no one can donate this troop who is on, they also can set troops at the troop bank.
