If a crew with Black Mark activated is transferred to a ship of his original nationality, does that ship become Cursed? If the crew goes to a Cursed ship, can he use his abilities normally? Can a crew copy Black Mark or does it have no effect since it’s a start of play ability?
The crew remains Cursed (+1 cost) and would need to be transferred to a Cursed ship to keep using its abilities (it doesn’t convert the new ship). The ship they started on would revert back to normal when the crew left.
Copying BM won’t do anything because the effect is determined at setup.
