Pretty sure the combination of Intimidate, Will-o-wisp, and Morning Sun make Arcanine usable defensively, even in OU. Especially since it can use its decent Attack stat with Flare Blitz to deal with squishier wallbreaker types, and heal back with Morning Sun. Rocky Helmet is silly, though, as is trying to go mixed.
Also, uh, Energy Ball isn't particularly silly on any special attacker right now, since Rotom-W is everywhere.
