I would use the star destroyer, just because i like it and would give tarkin a reason to live again but theres just no full team!
1. Reclass slave 1 as empire, not totally accurate but makes alot more sence than shoehorning him into rebels or jedi...
2. Add 1-2 F2p ships tie bomber and Interceptor, idk who the pilot could be tho, hopefully an empire guy i already have but is on the bench
3. Add vaders tie shards somewhere, shipments or fleet store and/or repeat the event please, i won only 15 shards last time vecause i was just starting out!
