Between Sith Sorcery, Pawn of the dark side, and swapping, you can make it difficult for your opponent to predict you. If you want a competitive squad, a few things will need to change.

I would focus on getting better shooter support, which will probably mean you'll want to take out your elite sith troopers, and your sith trooper captain and get Dash, RS or Zuckess. Zuckess would be prime in this set up IMO. Another strong option would be to drop CLobot as well, and put in Cad Bane, but I still think Zuckuss is a better option.

The other thing is the need to maximize your ability to utilize swap. Swap fodder and more activations is the big issue you want to address here and some of the activations being more mouse droids.
