I think it's good enough to have 4 teams we just need to get them full and then we can do a format where:
All teams play each other once (kind of like in a group stage kind of thing)
In the end, the highest ranked team plays the lowest ranked team to get to the final and the second highest ranked team plays the second worst team for a finals spot.
