unless GF makes him more broken by giving him a ground move that hits flying and levitate pokemon

also a physical one slorock can block but not a special one

If Solrock is a good check, so is Lunatone! The only difference between them is the physical/special attacks each one can take, and that Lunatone doesn't care much from burn while Solrock can trap it with Fire Spin and set up Rocks/Screens/Toxic with more ease.
