TM current gengar to lick fast move?

It's going to be like zapdos day where you couldn't TM. Sorry.

Highly unlikely given the treatment exclusive moves usually get.

Unlikely, but the answer will be online seconds after the event goes live in Asia. I'm more interested in whether it'll be possible to evolve Haunter into Lick Gengar since I'm sitting on a squad of good Gastlies.

Sadly no, but its not liek that Gengar's bad, still highes ghost DPS of anything nonlegacy, and theres situations where Hex's higher EPS lets youuse another charge move, putting it above SC, even if it cant get lick, its still good.
