Because the EMP device is unique.
You literally have no need for more than 1.
The only reason you'd ever get more than 1 Sabine's TIE is if you wanna run one of them without the uniqueness slapped on there. Which so far is pretty much Rex and Rex alone, since his condition will piss a lot of people off. Especially high dice people (FU DASH)
The only nonunique in this entire expac is the VI card.
