Oh, sorry about the confusion.I meant that both Glalie and Nidoqueen get Crunch to hit the Ghosts that block Super Fang for SE damage. Sorry if I worded it badly.
Also, it confuses me when people say that Super Fang helps bring walls into KO range. Surely if you can KO something at half health, then you can also 2HKO them at full health. I guess it eases prediction if you can 2HKO everything with your three regular attacks, but otherwise I don't get it tbh.
Yeah, that is the idea. If you can Super Fang something like Hippowdon on the switch with Nidoking, it is more beneficial than if you were to simply use Earthquake. Super Fang neuters all walls that aren't ghost type, and allows you to 2HKO everything assuming you have the right moves.
