>>18560047Arcanine is one of my favorites. But this said, the mega spread you propose it'll do nothing to help Arcanine.
Sure, it has a nice Bulk in 90/95/95, but it's still unable to take hits repeteadly.
115 Speed is an awkward Speed tier, being able to Outspeed a lot of things, but still losing to a whole group of Mons that can take care of you.
Finally, the attacks at 130. Nice mark, but it isn't useful at all. The only way to allow Arcanine run mixed is lowering its defenses, and you must sacrifice power for speed. That, or give up a moveslot in order to use Agility.
If you go with Flare Blitz, taking in account that Arcanine can take hits now, you also must use Morning Sun. If you're mixed, your best bet is Overheat and Solarbeam, the former being for a Hit'n Run Mon, and the latter wheather dependant.
This said, I suggest a whole new spread for MArcanine (Which it's very posibbly that won't exist, ever)
90/150/100/80/100/135
Or if you want to be overkill
90/165/90/80/90/140
