Pretty solid counters with the Ludicolo and the Darmanitan. I prefer stone edge over u-turn but I guess it's preference. A banded garchomp will be outsped by many ice types, so be wary of a weavile with ice punch or anything with ice beam, like the occasional dragonite. You have plenty of bulky physical defense walls, but your Sp. Def is lacking, mostly through Garchomp and Gliscor's 4x weakness to ice. Forretress doesn't have any recovery other than held items, so I would presume left overs > berries, but overall pretty good Sun.
