Ok, I swear on everything I wasn't hacking. I was doing a battle online and on the field was Decidueye, Tapu Lele, Ghost Oricorio, and some other Pokemon. Psychic Terrain was up and the Oricorio was at 1 HP. I forgot Psychic Terrain was up and I went for Sucker Punch. When I thought I played myself, the Sucker Punch landed and knocked out the Oricorio. Has this happened with anyone else?
