I'm on the last gym, I can face the gym leader, but all of my Pokermons are underleveled. (All around 30, with my temp. JYNX being 27)
Now, where do I train? All that's out there now for me to train on are Lvl 22s, which takes forever. I tried to train by battling the people in the gym. Worked for a little bit, my JYNX gained a few levels, but, now where do I train? Everyone inside the gym has lost to me except the leader.
tl;dr: Where do I train for the last gym?
