>>28865377I don't have any rules, but because of HMs I almost always have a water type and a flying type for convenience. That's one reason I'm excited about Sun and Moon because it looks like we won't be bound by that.
I also usually have a starter on my team. The first time I'll choose my favorite starter and the 2nd and 3rd replay I'll choose the others. I usually make my team out of Pokemon I haven't trained before, but sometimes I'll reuse favorites.
