So folks, I started a new save and swept through the 12 gyms with a six-man squad. Even though I permanently replaced such mons as pachirisu, my army could stand its own even against charlotte (after many revives and hyper potions). Since E14 is over and my team is sitting there doing nothing I would like to ask for improvements/replacements on the followng team. Note: I won't do E12 breeding, though.
