Professor Ray
Points: 10
Ability: Black Mark. Ability text on Cursed pieces cannot affect this ship.
As written, this would prevent most Cursed crew that were placed on Ray’s ship from working if he Black-Marked it. The few that would still work would have to directly target opposing ships/crew without doing anything for or to this ship at the same time.
A Chieftain is the only generic that would work. All-Powerful would work only on a 5 or 6. Fear would work.
Assuming this is meant only to block opposing Cursed abilities, you should specify that in the text. If you want to keep it as-is, you can drop the price significantly.
