Starmie is definitely a check but is easily taken out by the numerous bug types and electric types this gen and at least for now even scizor runs brutal swing which is dark type . And with all the ghosts out there the rapid spins are blocked even easier . I disagree that it ' s gonna be as high usage as you say , UU minimum but low OU is more probable . I do agree it is good against these mons but it ' d have to be hydropsychic or scaldpsychic and I don ' t see offensive often mainly just a HP speed set , see the psyshock and scald calcsAll Timid nature 4 SpA Starmie Psyshock vs . 252 HP 252 Def Toxapex 92110 30 . 2 36 . 1 % guaranteed 4 HKO after Leftovers recovery 252 SpA Life Orb Starmie Psyshock vs . 252 HP 252 Def Toxapex 151182 49 . 6 59 . 8 % 80 . 9 % chance to 2 HKO after Leftovers recoveryPsychic calcs 4 SpA Starmie Psychic vs . 252 HP 4 SpD Toxapex 144170 47 . 3 55 . 9 % 18 . 8 % chance to 2 HKO after Leftovers recovery 252 SpA Life Orb Starmie Psychic vs . 252 HP 4 SpD Toxapex 237281 77 . 9 92 . 4 % guaranteed 2 HKO after Leftovers recoveryAnd not that it should ever be done but marowak v scald 4 SpA Starmie Scald vs . 252 HP 252 SpD MarowakAlola 146174 45 53 . 7 % 1 . 2 % chance to 2 HKO after Leftovers recovery 252 SpA Life Orb Starmie Scald vs . 252 HP 252 SpD MarowakAlola 237281 73 . 1 86 . 7 % guaranteed 2 HKO after Leftovers recovery
