Nothing in the game was very challenging. Victory Road was the hardest and even then it was only one or two trainers in it. I swept two of the elite four. Champion was somewhat challenging. I had pokemon 63lvl-78lvl (btw, it wasn't hard to train pokemon at all with how exp share works now. I feel like I barely used my party). Overall good game but easiest pokemon yet because of how many good pokemon were available right away.
