Since nobody decided to help me with my team choice, I went with Aron. I figured that I wouldn't want another Ice weakness from Axew and that Tynamo would just be a pain in the butt to train. So, after a little bit of grinding, I was ready for the gym.
...The extremely dangerous wind-tunnel gym.
After finally getting past the danger, I defeated Skyla with a combination of Rock Tombs from a Lairon and Thunderpunches from a Lucario. Then I stepped right aboard the plane to Lentimas Town. So, I then went through Reversal Mountain, and stopped to rest in Undella Town.
...Or at least I would have, had I not forgotten to save after healing. So now I am back at the beginning of Reversal Mountain.
...I'm about to unleash my rage.
