Thank you, I'm going to try this with Crobat! I hope it works.

Hey guys, Is there any viable strategy to beating this gym? I've tried setting up sunny day to boost my fire types but his pokemon can still sweep my fire team. My fire pokemon are: Arcanine, Houndoom, Talonflame and Castform for sunny day. I've also tried using rock types like Onix and Lycanrock and I still can't beat him. I'm literally stuck in this gym. I would be so grateful for any suggestions.
