If you want to organise your own clan battle you must first of all contact the leader of the enemy clan and discuss whats going to happen.
There are 2 formats:
Classic 4v4Each clan has 4 players who play in 1v1 battles
PointsOver a week long period the two clans play against each other scoring 1 point for a 1v1 win, 2 points for a 2v2 ect. Each player can play against the other clans players as many or as few times as he likes. The results of each match will be posted (a screenshot) on a thread and the mods will keep track of the score. At the end of the week the clan with the most points wins.
Knockout TournamentDoesn't really need an explanation, just a knockout tournament with players from the 2 clans and 1 winner
When you and the opposing clan leader have sorted this out, reply to this thread with the names of the 2 clans and the format you'll be playing and get someone from their clan to confirm it. The mods will create a thread to post results and keep track.
Feel free to ask any questions or post suggestions
