Given that the 3.0 cifal was included in
Polyhedron #145 "as a special treat", because it was "the
Fiend Folio monster voted "suckiest" by the members", I'm not sure it would stand a very good chance of being accepted in a
Dragon proposal. That said, two things about the
Polyhedron version make the 3.0 Cifal immediately superior to the original: (1). It is no longer a 'colonial insect-formed artificial life'. Now it is just a cifal. (2) The artwork is way more inspired. I'd run away from the 3.0 version. I'd call friends over to point and giggle at the 1st edition version.
The new version is a Huge Aberration (although the picture makes it look Large, at most) with a "semi-solid swarm" special quality that allows it to make a slam attack and resist
gust of wind-type spells. But the description really need some explanation for
why a bunch of insects would fly around in humanoid form. Especially since this means giving up their fly speed, for a land-based speed only (forced by "the need to maintain coherence of shape", y'know).
Still, I'm forced to admit that a strong sense of nostaligia would get the cifal a vote from me
