Was thinking it would be fun to be able to challenge your friends to sabo matches, for example if you had 4 friends and you wanted to 2v2. Or just two people who wanted to 1v1 (Or 6 for 3v3). Take out any rewards, experience, or rankings so nobody could cheat their way to the top of the leaderboard, maybe even make a separate challenge mode. Could also help with being a sort of sandbox mode so people can practice cade and trap strats. Also wouldn't have to wait for a match.
