Im still trying to work on Intimidation and Zeb on a ship. Just too much fun of a combo.
That upgrade others don’t use but you do.
Flechette cannons.
...On a TIE/D Vessery, alongside another TIE/D running an Ion Cannon, but still... 
Best moment was when players - at a regional tourney no less - wanted to double check the card because they couldn't quite remember its exact specifics. That's when you know a card is niche. 
It was more a combination of cards for me.
My Corran used Lone Wolf, Stealth Device and Sensor Jammer. Flechette Torpedoes too if I was expecting to see (pre-nerf) Mindlink.
I used to pair it with Miranda before I liberated myself from vile mistress of the Rebellion. Sadly Corran hasn’t hit my table since I sold the K-wench.
I’d fly that combo on Corran again if I had the right fifty points to fly with it. Maybe I do and I just haven’t realized it yet...
...you’ll have to excuse me. I’ve got to get back to Aurora Squad builder.
