Okay, we'll use our own pokemon for each of the five contests we'll be participating in. You'll be assigned into a group, (Group A, Group B, Group C, ect.) and a group is composed of 3 trainers, each group will participate in all 5 contests. Coordinators use their OWN pokemon for each of the contests. They'll use ONE pokemon for each contests. Though judges will mark down points if you use a pokemon for two contests in a row. So the best thing to do is keep alternating your pokemon until you've completed all 5 contests.
At the end of the contests, the leaders of all four groups will face off in a double battle. The trainer on the winning team with the better score,evaluated by the judges, will the get the moon stone, whille the trainer on the winning team with the lower score gets a commemorative halloween Pewter Medal.
