>>20994640I got to 146 with Sash Breloom, Mega Scizor, and Vest Garchomp. Opponent opened with a Pinsir. Switched to Scizor to wall and set up SD, but it caught me with a Guillotine on the switch. And then the other Pokemon were Togekiss and Glaceon, so I didn't stand a chance.
Basically, you want to use Mega Scizor, Mega Kangaskhan, Mega Charizard, Greninja, Dragonite, and honorary mention for Aegislash and Garchomp, as well as supporting Pokemon for everyone mentioned. There's also the Durant approach, but ain't nobody gat time fo dat and there's still the chance to lose with it.
And don't use or try to refrain from using moves with less than 100 accuracy like
>>20994659 suggested, since the miss will cost you the game. I learned that the hard way when I was using sweeper Slurpuff one run and Rotom-W Hydro Miss another run.
