text: The target of Rex Nebula's ability will become a Vehicle artifact until end of turn. It will lose all of its previous card types and subtypes, but it will keep any supertypes (such as legendary) it previously had. If the target of Rex Nebula's ability is a creature, it will lose all creature types (such as Zombie) it had until end of turn, and becoming crewed will not cause it to regain those subtypes.
