how to start cwl in coc?
The minimum number of members to participate in this CWL is 15. Starting in April 2019, the Clan can sign-up to 15vs15 or 30vs30 wars. After the sign-up, there is no way to change, and you must go through the 7 days of war with that size. Clans on the Champions League can only make 15vs15 wars.
