I thought "OMG, strictly better Blood Artist!", too. Then I realized it only counts your own stuff. Having actual power and being a human are upsides, but I don't think it quite makes up for getting fewer drain triggers.
Zulaport Cutthroat was discussed here in The Random Cube Card of the Day Thread. Studies have shown that visiting the thread decreases your chance of being mugged by 80%, what are you waiting for?!?
(Spoiler: Blood Artist is the better choice unless you really have to have that 1 power or need redundancy.)
Any reason not to swap out Blood Artist for this guy?
Edit - Just saw it doesn't trigger off your opponents stuff. Nevermind!
Draft my cube!
