I noticed you lack entry hazards and a rapid spinner. It seems to me like your team hates entry hazards, so you might want to include Forretress to the team and say bye to Ferrothorn.
Forretress @ Shed Shell (You can use Leftovers if item clause is not on but I doubt it.)
-Earthquake (or Gyro Ball but Earthquake to hit Magnezone on a switch.)
You might try using Specs Chandelure/Gengar to block spinners and fighting types. I'd go with Specs Flash Fire Chandelure since you don't need Ground type immunity when you have two who are immune to it. But you could go with Gengar for the speed.
