Remember to note all of Pokemon_is_awesome's team that you saw, including moves. That way you can compare with his future opponents to make sure he is using the same team.
Actually, the promotion system was an experiment. I ultimately decided against it. Instead, you may merely rechallenge XDLugia and LeinGodF8 (free team, max 3 OUs, as before) as many times as you want. You know, within reason. Don't bug them all the time.
