World's biggest Incineroar stan
You mean Perism/Lum Berry? Chesto heals sleep.You could use Chesto Berry as a held item. I even used Honchckrow Swagger on my Skeledirge. Chesto Berry removes Confusion after Swagger. Swagger along with Torch Song and Fire Terastallize removes my ghost type weakness. (Skeledirge gets SP Atk boost with each use)
This gave me a fast sweep of the Paldea Ghost gym.
