Talk:Sabine Wren (Crew)/@comment-67.222.225.40-20151222162657/@comment-454133-20170804230237

Mutual exclusion means you can't use a card named Sabine Wren multiple times in the same fleet (e.g. two sabine crew cards, or sabine pilot and crew). I don't think that's the case here -- they're just talking about edge-cases where it's interesting to use the sabine crew (a B-Wing or HWK carrying a bomb).
