Hey, you still need rough skin garchomp? I have an old spitback from when I was first breeding up the IVs you can have for free if you want. It has the correct ability, nature (Jolly), and a few egg moves if you're interested.
Idk most physical attackers in UU carry a move that can hurt Golem pretty badly after the DC, since it has an abundance of weakness. I'm saying you could slow them down first and maybe even get lucky with Parahax. I'm just saying, also Good Game. You have a cool team ^^
