I remember in at least one game, one of the reqs for maxing the trainer card was all trainers defeated. Well, if you defeat a gym leader, it makes it impossible to battle the any remaining trainers. I skipped a trainer in the second gym, and am now curious if I made it impossible to max my trainer card..
