>>48167058>>48167086ttar has resistance to normal, ghost, and dark priority moves, which is pretty useful. It *is* weak to mach punch, vacuum wave, aqua jet, and bullet punch, which is a good portion of BW/XY/SS OU priority. Still, I'd argue Ttar would a monster in BW onward if it got shell smash. For completeness' sake, here's a list of the users of those priority moves from BW onward.
>>Mach Punch>Breloom>Conkeldurr>Hitmonchan>Hitmonlee>Hitmontop>Infernape>MagmortarSome of these are legit threats in BW, especially Conk and Breloom. XY onward added no new users of it, and SS took most away.
>>Vacuum Wave>Blaziken>Breloom>Gallade>Hariyama>Heracross>Hitmonchan/Hitmonlee/Hitmonlee>Infernape>Lucario>Machamp>Mankey>Medicham>Mew>Poliwrath>Scizor>Toxicroak>Kartana (SM)Most of these would rather run Mach Punch. The only ones who would maybe run VW would be 'Nape and Lucario, but both have much better things to be doing. Scarf Infernape would actually be a much better way to revenge kill ttar.
>>Bullet Punch>Hariyama>Hitmons>Lucario>Machamp>Medicham>Metagross>Scizor>Toxicroak>Pangoro (SM)Mega Lucario, Mega Medicham, Machamp maybe, Metagross (Mega or not), and Scizor in any form. Banded Scizor BP in particular OHKOs at -1, as does CB Meta's BP after rocks. Most of the rest are no problem, even at -1 defense.
