I don't even understand the essence of the complaints; let Rebel provide a full double table in which the color of ALL teams will change every 3 games. Otherwise, it's just a bunch of complaints; I would, in the organizers' place, put him on a blacklist, as he causes trouble in absolutely all tournaments he participates in, and for no reason.
P.S. In any case, changing something after the start because of 1 or 2 players will cause much more of a stir.
