the only reason i am playing this meta is because i love the stall playstyle so i think i'm gonna scrap my head 'till i find a decent answer to most mold breaker users (kyu-b and pangoro are the best ones i think).If you mean passive stall or pp stall, ofc you are gonna lose. Don't use it. If not, Fairies + Intimidate are checks. They bypass Moldy. Try Clefable or Magearna with defense boosts. Pangoro is slow and if it uses Triage, Gunk Shot wouldn't be boosted, so you can Moonblast it. If you're scared of Contrary, carry Buzzwole, which should completely wall it.
