the unupped is actually more powerful than the upped, though i would probably run them both in the same deck. think about it, if you draw it first turn you can just play out your whole hand. you might lose hp, but its 2 dark for a 2/2 minor vamp, so use this twice, and play the vampire, nothing lost. im not saying the idea is bad, im just saying with the vampire synergy it might be OP in dark.
