i liked the defensive set even when sand was still legal C: and i like it now although i strongly prefer will o wisp to toxic since it lets you do cool things like beat Band Flygon one on one if you're at 100% and you managed to intimidate him. you're also clearly beating weaker guys like Rhyperior if you manage not to miss and generally they stay in to use SR on you on the first turn if you lead with Arcanine. So if you're weak to say swampert/Rhyperior then having a defensive Arcanine is a cool way to burn them ~75% of the time (accounting for accuracy). of course you could use something random with HP Grass or Grass Gem Xatu hehe but its nice to have something that at least checks roughly 70% of all UU Physical attackers while being the tiers best straight up counter to a few of them (probably the best physical victini counter for instance).
On that same note I bet Bolt Strike Victini is going to partly eclipse Arcanine within a month or two because Bolt Strike>>>>>Wild Charge while already V-Create>>>>>Flare Blitz. The only thing Victini really lacks over Arcanine imo is Extremespeed but Victini can for instance outspeed and KO Timid Nidoking or Meloetta both of which outspeed and KO Arcanine while absorbing an Extremespeed, so the prority advantage isn't as decisive as you might think. Incidentally Victini's stats are almost totally superior only having slightly less attack which you generally can't tell because Jolly Scarf V-Create is going to be hitting as hard as LO Adamant Flare Blitz or actually slightly harder iirc.
what i'm saying defensive Arcanine=very cool if you keep in mind a large hazard weakness and offensive arcanine=before you use it look at Victini or Darm (which incidentally is stronger than Victini assuming equal sets).
