Wow, I'm having bad luck getting your messages on time. LOL I just checked in now and now have to arrange two battles, the other being the Prism Cup one. {XD} The question is which to do first as, since the Prism Cup one isn't a Gym battle per se, I can actually legitimately try to prepare my team directly for the battle without trying to plan ahead for challengers, which normally goes against convention.
Of course, I could very well keep those changes on my team for the Gym if they work well. So either we can battle before that match or we can battle after I change some things for that match. What is your preference?
