Its like I've forgotten how to build a squad without it. This week my LGS is running a non DCI 150 point tourny with the special rule that the squad must include at least 75 points of force users. So I was thinking Thrawn or Vong for some force immunity. This is the first idea I scrapped together for Vong. I know its not great since to go Vong that means my force users have to be all Fringe and that doesn't leave a lot of options. Or a lot of room for the Force Immune Vong part of the squad

Cade Skywalker, Bounty Hunter
Jolee Bindo
Vong Jedi Hunter x3
Ugnaught Demo x2

If that can't be tweaked into something useful I can always go the Thrawn route and play the basic B&B build with Vader, JH as my 75 points of force users. It should do well with all the force users I'll be facing.
