>>43763571Volcarona was historically an all-or-nothing mon that looked for the sweep.
>>43763594Greninja got a lot of stuff in ORAS that let it muscle past its last few reliable checks, which is what pushed it over the edge. Meanwhile, Cinderace has plenty of stuff it can't stay in on. Both Hippo and Toad don't give a shit about what it runs, especially Hippowdon, who doesn't need any attack investment to OHKO it 100% of the time with EQ, brings in Sand Stream, is never 3HKO'd by any sets lacking LO, and has recovery to check it repeatedly and can set up Stealth Rock. Gyarados does fine so long as it doesn't switch directly into Gunk Shot, which Cinderace cannot afford to spam until after Clefable dies so it doesn't burn all of its PP while the fat fuck keeping everything else alive with Wish+Teleport. Zeraora is the major stop-gap to prevent it from cleaning late-game because Plasma Fists do 74.4% at worst so any chip is lethal. Bulk Up w/ LO can let it muscle through a lot of threats but it will lose to many others because it's coverage options are very lacking, especially vs Water types, and if you aren't running Boots, getting it on the field is a pain and it outs you as not running Boots.
Greninja has more than just speed over Cinderace. It's immune to Psychic on the switch so it's easier to get on the field, it isn't SR weak, it has a much better move pool, Spikes to pressure switches, can run physical, special, and mixed sets, could use its ability defensively by virtue of its move pool, etc.
