Oh yeah, Parting Shot Scrafty is a great idea, i'm wondering why i didn't think about that. This moves will give it tools to diferentiate itself from conkeldurr and will allow a great ability of creating momentum, maybe better than U-turn.
I wondered in the past what pokemon could have fur coat, and when you look for that, you notive there are few furry pokemons ... Arcanine have a fur right, is this new ability will bring it more than intimidates ? Obviously yes, but arcanine stay a fire type, taking 25% on SR, recoil damages on flare blitz/wild charge, i'm not sure that will allow it the possibility to shine in OU.
Harvest Torterra, well let's take all the grass pokemon from 1st generation and give them harvest, they will probably make something of that ability, but i think the strategy around harvest slow down the game and have no synergy with the other teamates, so no.
No Guard Noivern, it's interesting, but see only two moves taking profit of this new abilities : focus blast and hurricane. That means loosing a good abilty named infiltrador that allows it to check Kyurem-B, even behind a sub, but why not ...
