ORRRRR
We could potentially revert to the previous clan league method of having 4 (or more) players and numbering them 1-4, and playing the games out as follows:
1 vs 1
2 vs 2
3 vs 3
4 vs 4
1 vs 2
2 vs 3
3 vs 4
4 vs 1
1 vs 3
2 vs 4
3 vs 1
4 vs 2
1 vs 4
2 vs 1
3 vs 2
4 vs 3
With a tiebreak if necessary.
