Hey guys!
So, I'm new to this game so I haven't gotten very far. Still, I found something worth mentioning:
You know those Audino Trainers? Well, the one in Celeste City only has Pound and Healing Wish on his Audinos. Anyway, I found out that when facing a ghost-type Pokémon (such as a Duskull or Shuppet from Weeping Depths and Weeping Hill respectively), his Pokémon will immediately use Healing Wish, giving you a free KO.
So, how did I abuse this? Well, I always start off with my ghost-type then switch out immediately. Then when the next Audino comes up, I go back to my ghost then rinse and repeat. It's a neat little trick to grind your Pokémon.
Anyways, I'm not sure if all Audino Trainers have the same moveset which means that it might not work everytime but still, it's worth a try whenever you see an Audino Trainer.
