Okay. Tyranitar can run Pursuit as a trapper, or Stealth Rocks to free up a move on Hippowdon. Earthquake is nice and all but with 2 other EQers it's kinda redundant.
If your Hippowdon is 1v1ing a flying type, well that's not gonna end well, is it? Rock Slide or Stone Edge may be nice. Roar can be replaced by Slack Off since Hippowdon is pretty bulky, and as the only hazards you have are Stealth Rocks, roar is not gonna be as useful.
Skarmory.. Brave Bird may be too dangerous to yourself as Skarmory has not so good base Hp. Drill peck is a good alternative, with decent bp and no recoil
Lose Shadow Punch on golurk. With Bisharp's dark STAB a weak 60bp move isn't gonna be useful. Probably should replace with Fire Punch for Durant, Ferrothorn, Forretress and Scizor. Rocks can be replaced by another kind of coverage move, maybe Ice punch
I'm gonna be honest here, that team may not be good for Redemption. It's very, VERY physical and lacks key coverage such as Ice, Fire, Fairy and Electric. A sand team is a good concept but It will need refining to be viable. An Aurorus will give you coverage with Ice and takes the place of Electric with Freeze Dry. A Garchomp would also be good with Fire Blast/Fire Fang and Rocks support. It's also fine to not have all your Pokemon to be immune to Sandstorm - In fact it gives you a lot more coverage and is far more superior than having a team purely based around 3 types.
