I use Tie Silencer, FO Tie + FO SF Tie in the starting line-up under Tarkin in TW. Reinforcements are Kylo's Shuttle and usually Reaper, Slave 1 and Lando's Falcon.
The tactic is to first stun a ship with the Silencer, then use FO Tie's basic. And lastly use FO SF Tie's special on the enemy attacked by FO Tie, to assist with Silencer and stun 2 enemy ships or even take out one of them before the enemy even moved.
First reinforcement should be Kylo's Shuttle and then I use "Strike Team" and target the Shuttle to give the whole team Turnmeter and advantage.
