I'm actually doing another run right now to test the wild poke levels, and I don't know if my team just sucks this time or what, but I could not beat Alicia.
This is what I have at the moment, still challenging, but nowhere as bad as it was:
(Also, had gal ponyta in place of azumarill at first, but realized it's pure psychic, so haven't tested with azumarill yet)
