Sorry, but no (at least for me). I understood that they are "part" of the Nightwalker, but since they have their own card and their own figure(s), they need their own price, imo. Lamaclown's example of the Rechets is perfect-you have no idea if you'll get to use them, but you have to pay seperately for them anyways.
They're a cool idea, but I'm not ready to break so far away from HS convention yet (Fanscape might take us there eventually, though
).
