The Rebel Aces have 3 title cards for the 2 specific ships, a very focused expansion.
3?
I could understand if you said 2 titles or 4 title cards, but 3?
Sorry, I mean 3 unique types of Title cards; so out of the 6 types of upgrade cards, 3 of them are specific unique Title cards geared towards their specific ship.
I still don't understand? Rebel Aces comes with 2 titles, one for the A-Wing that grants a 2nd EPS and one for the B-Wing that grants a crew slot, with 2 copies of both. Where are you getting the number 3 from?
I think he's trying to say 3 types of upgrades that can only be used on specific ships. Namely Prototype Veteran (A-wing only), Bwing ? (B-wing only), and Chardaan Refit (A-wing only).
