>>56991469I'm pretty sure Dragonite can do it.
252 Spa, 252 Spe, 4 Atk, Mild, Dragon gem Dragonite.
(As far as I can find, gems aren't used if they hit protect. If someone can confirm this with a video, I'd appreciate it.)
Draco Meteor KOs max/max+, forcing Turt to run Haban berry or Sash. Sash just gets sniped by E-speed next turn, leaving only Haban berry to get another turn.
>Haban+Shell SmashAfter a shell smash, Turtonator can invest to be faster than Dragonite and Draco Meteor will ko through the multiscale with only 128 evs.
Unfortunately, the -2 def from smash means he gets KO'd by E-speed.
>252+ SpA Dragon Gem Dragonite Draco Meteor vs. 252 HP / 128+ SpD Haban Berry Turtonator: 229-270 (70.6 - 83.3%) -- guaranteed 2HKO -- 250 damage>4 Atk Dragonite Extreme Speed vs. -2 252 HP / 0 Def Turtonator: 114-135 (35.1 - 41.6%) -- guaranteed 3HKO -- 125 damageAnd that's basically it. Turt needs two turns AND a way to live the initial draco meteor. Shell Smash and Custap are largely ignored by E-Speed, and it needs to either hit twice or boost over multiscale. I even tried dumb shit like Rock Tomb, to slow down dragonite while breaking multiscale, but I just can't find a setup that gets the kill. It doesn't care about status since it goes first and is a special attacker.
