When there are 10 eligible players in the clan, the leader and co-leader have the option to start a clan war. You will be matched with a random opponent (so, for now, no options to start a direct war with a specific clan!) and the two day process of the Clan War begins.
Preparation Day & Battle Day Clans fight a War each day of War Week. Whenever a War goes into Battle Day, Preparation Day begins for the following day's War. Each Preparation Day is a chance for Leaders to finalise the line-up for the upcoming war. See what Clans a Player has been in. All the best War Leagues use Clash of Stats to vet Players! Find a Player (enter Name or Tag) Add criteria. Despite of your selection, you can take as many players as you want to the CWL. Even though the war size is 15 or 30 members, you can pick more players to the CWL, but later-on you must select only 15 or 30 to go to the war. Since the event is seven 24-hour wars, you can substitute members every day. First things first: in case you haven't done so already, you must do the obvious in order to get the chance to participate in a Clan War: rebuild your Clan Castle and join or create a Clan.

The troops you build in your normal base will be used to attack in the Clan War. Make sure your Heroes are at full health before attacking so they can be used during the Clan War attack. Your Clan Castle is automatically recharged with donated troops between attacks.Clan War eligibility is simple: Your clan must have at least 10 members. You can only wage wars in increments of 5, giving us the following available wars: 05 v 05; 10 v 10; 15 v 15; 20 v 20; 25 v 25; 30 v 30; 40 v 40; 50 v 50; If your clan has more members than is required for war, then the eligible members with the highest trophy count are A4lv3s.
