I was looking at the moveset changes on B2W2 page, and I noticed that Growlithe/Arcanine now have access to Outrage. With a new powerful physical move other than Flare Blitz, I'm expecting Arcanine to get a little more use. Maybe not necessarily OU, but more use in UU. This set I may want to use.
Arcanine@ Absorb Bulb
Ability: Flash Fire
EVs: 252 Atk. 252 Spd. 4def.
Sunny Day/ Thunder Fang
Set up Sun to boost the power of Flare Blitz, and in the unlikely instance where Arcanine takes a hit and lives, you can use Morning Sun to heal up a bunch. Outrage is there for dragons, mostly, but also for anything else that resists Flare Blitz. If you put this on a team with Drought Ninetails, you can replace Sunny Day With Thunder Fang for coverage. Absorb Bulb won't boost his attacks much, since he's physical, but it will at least allow him to take a water hit.
I'm not that good at competitive battling but this just an idea that took some inspiration from a youtube video about the morning sun thing. It's just an idea I had.
