For Zaul Arena team - Sith Trooper or Assassin?

I am running, EP G10 (L), Maul G10, Vader G9, Boba G10, and Sith Trooper, 3* G9. Everyone else is 7*. Sith trooper is the reason for my success. No I may not always go first but my Boba throws ability block down and then EP's special gives taunt. From there its game over.
