>>56090759I did use Lucky Egg actually, it was for this little guy I caught in the Celestial tower a few days back, and I wanted him around the same level range as my team. I fought the trainers I could fight on every route that didn't hide them behind HMs save for Surf, I only had 6 pokemon when I got to Drayden, and I was on normal mode since I didn't use PkHex to unlock Challenge mode. That was my honest experience. If Challenge Mode is really just a level adjustment upwards, then his pokemon should more or less reflect the levels of the gym leaders if he isn't deliberately grinding above the Gym leader's levels.
