The Reloaded expansion for standard Munchkin adds High and Dark modifiers to your class. If I get the High card without already having a race, I become a High Human. If I then get a Race card such as Elf, do I become a Dark Elf? Or do I lose the High card because I changed races?
Both High and Dark say: "Add this card to a race card". In my reading this means that you can't be a High Human, and so the question is not applicable.
