I'm thinking Snapshot on something with Accuracy Corrector.
The SF TIEs get a lot of mileage out of Accuracy Corrector already.
Any of the elite Advanced pilots can pair it with Accuracy corrector or ATC.
You would need some serious Target Lock synergy to get that free Crit result added to the attacks.
I'm thinking 6 TIEs would do some serious damage to enemies. You get one TIE to block, and the other 5 in formation will probably have a shot.
Other than that, having Tractor Beams, or some of the scum crew that mess with Defender's dice is a nasty way to push damage through.
Adding a specific result (a blank, eye, hit or critical hit) is modification,. So no atc or acc corrector combo. You can add dice though.
