I saw a video detailing an interesting Interdictor build and thought I would put it in a list.
Objectives: Most Wanted, Fleet Ambush, Intel Sweep
Interdictor-class Combat Refit(flagship): Grand Moff Tarkin, Interdictor title, Wulff Yularen, Engineering Team, Targeting Scrambler
Victory I-class Star Destroyer: Expanded Hanger Bay, Enhanced Armament
Arquitens-class Light Cruiser: Enhanced Armament
Raider-I: Instigator title, Rapid Reload
Howlrunner+3 TIE fighters
399/400 points
The idea is that the Interdictor is very very hard to kill. Wulff ensures that you always keep your Engineering token. So with an Engineering action, and spending the Engineering Token, you have 9 points a turn thanks to the Engineering team. Thats 4 shields+move a shield or 3 damage a turn, or some combination.
Then you also can protect yourself and the other ships with the Targeting Scrambler, which thanks to the title you can ready each time they or you activate a ship.
The Victory SD can move all the fighters at once, and being the I class it synergizes with the Targeting scrambler. The Raider also can heavily benefit from the scrambler as well, and screen for fighters at the same time.
