For the record, this is pretty much the first game I matched/had close levels with the elite four while only using trainers (And I guess four audino along the way) to level up. 5th gen in general seems to have some easier endgame trainers.
I stepped in with a team of level 56s, and didn't have any huge problems. Though to be fair I had a move or three for everyone.
