Think this is something that could nice to have in this game.
It could be something like you need to queue up for, to find an opponent, and when there is match found have to accept.
Then we have 1min to set a team, and the match start. We will have our own board, board sharing could maybe also bring a twist, 30 sec to make a move or else no move. (turn pass) And after x turns there will tier break to help end the match.
