Powerful fighting types, most notably Scrafty, could give this team some trouble. Scrafty, for example, can take out four of your team members with STAB alone. The only pokemon who handles him (somewhat) is bronzong. You could put superpower on azumarill tho handle this I suppose, but that still doesn't handle other notable fighting types like Guts heracross and Hitmontop. Putting zen head but on bronzong could handle this I suppose
