I like it, but its probably too good at that cost. Maybe as a 3/2 or 3/1?
Vampire Nighthawk says its pretty cool. I can't see this being as heavily played as the hawk.
True. It's in most ways worse. Vigilance more useful on something with deathtouch, but reach is objectively worse than flying.
Despite that, I can't really see WotC printing it. Kessig Recluse shows how much they think of green wrt anything comparable as the Nighthawk.
