This always seemed like a cool idea. And in between war and the next war clan wars could start. Although that would be done with a single elimination.
Clans would consist of 5-10 people. So the way tournaments would go. People would face other clans. The clans all need to be around the same size or one team would be handicapped.
So the two wars would face 1v1s. Until everyone on one team has loss.
So lets say we have players a b and c on clan cool
And players 1 2 and 3 on clan loser.
It would be arranged as:
A vs 1
B vs 2
C vs 3
Then lets say a wins 2 wins and c wins.
it would be arranged as
A vs 2
C vs 2
then lets say that player number 2 wins both his matches then he wins for his clan.
And if player a or c beats him once then there turn wins.
Or it could be just a 1 v 1 where player a and player c choose who will face player 2.
