slave 1 only has 1 crew slot, so no room for Han.
see how nice that works?
if you really need to use a ship then you sacrifice that crew slot, and the ywing and z95 are already rebel, unless......
the card is a crew slot you can put on any of your ships and allows you to take 1 S&V ship of anytype, but then this opens up the possibility for Fett and Han...........hmmmmmmmm.
probably never happen, but sounds cool, IMO
