Trick Room isn't very good on a team with two Scarfers. I would switch Heatran and Excadrill to more Trick Room abusers or just not use Trick Room.

Stakataka is too bulky for Sash. Give it an Air Balloon, Shuca Berry, or Chople Berry instead. In all honesty, you should just ditch Trick Room completely. It's not a very viable playstyle, and you've got Scarfers/fast Pokemon.

Side note: Yes, absolutely use an Aegislash. It's practically mandatory on Steel teams, in order to soak up Fighting moves.

Sash was used pretty much every time btw. I'll take out tr then.
