you can tell i was tired because i forgot fairy and i thought bisharp was fast against a pokemon that blocks priority fsr
point still stands though, as more generally, any quick physical attacker in the tier without a fire move coverage is forced to either switch out or get blown away, in a tier that's getting pheromosa, a physical glass cannon who's more than fast enough to ignore priority. should stall somehow survive all of this, bewear and chansey could also be a pretty good combo
