OK, first idea using Vader's Apprentice, Unleashed. Actually, I think this may be the first squad I've posted on here at all.
Vader's Apprentice, Unleashed 48
RS Emperor Palpatine 40
Vader IC 53
Admiral Piett 20
Mas Amedda 8
ST x5
Ugo x2
With Vader leads the charge here. With Deflect and Riposte, plus Palp's Force Points if necessary, he should be able to hang around for a while. Plus, if the opponent wants to run a Force Defense character, then Vader and the Apprentice can tag-team him to just Melee Attack him quickly to death. Can also lead with one or two of the Stormtroopers, since they shouldn't die too quickly.
Once the Apprentice is able to start nailing people with Force Lightning, they'll go down fast. The Opportunist Troopers will wail on whoever gets activated because of the Lightnings. Would be a game of balance and keeping most of the squad together (except for Piett and Mas).
Could swap out Palps for Thrawn and an Ugo instead in order to give the Stormies a better chance to hit, some Force Defense of your own, and the init control to be able to stun an opponent at a key time. In this set-up, you'll probably only get 1 Force Lightning, maybe 2 if it ends up being a fast moving game.
