This would be a event house event.
Basically there are 5 "courts" and 10 teams of 5. it would be handled like gang spar. If your team looses the spar you go down a court, if your team wins, you go up a court. The highest court is called the "Kings court" and the last team remaining in that court after 10 or so spars wins the event.
Also, if you wanted to make it longer, the team of 5 that won could be separated randomly into 1v1 matches with the same rules except elemination style. Only problem is a person would have a bye(or however you spell it) for a round so it would be a little luck.
Got this idea from playing basketball today lmao
