Mareanie Hyper Offense in Tier Shift. Blacephalon is the main sweeper here. You need to have No Guard on Blacephalon, along with Merciless. One layer of Toxic Spikes is good, but if they run out, don't stress. The team still does well without Merciless abuse. https://pokepast.es/9cec222dfaf566f7
Another cool squad with parting shot perish song pyukumuku, multi attack flying gyarados and scarf d energy hydreigon to outspeed specs pult. Also slowking has two cool S moves, very cool fellas on this squad.
OU team with speed control for sub coil dunsparce, which beats the high usage bulky mons, can stop choice spectrier, paralyzed urshifu, and has beat buzzwole, nidoking, and volcarona in testing when defoggers are gone. Stun spore for ground types, and moonblast for darks and sptakers from ribombee help beat usual problems for the team. Try it out and you'll see the way. https://pokepast.es/3c14477014013967
Another cool alphabet cup team before alphabet cup is gone: Sheer Force Conkeldurr (pokepast.es).
Everybody uses Guts Conkeldurr but Sheer Force/Life Orb provides good coverage and STAB with Thunderous Kick.
Maybe it could be useful to you the team I used to get reqs last night: https://pokepast.es/302af622330a759e
It features 4 attacks Ace, orb np hydra and orb urshifu, which whittle down their respective checks and counters. Fire Blast Chomp is meant to lure Buzzwoles to ease Urshifu's role (at being the broken mon he is).
Watch out for rain, chomp and grass spam, though, these match ups are all very hard.
Yo Joey I got proof here that Urshifu isn't broken. Got colbur berry Slowbrow with counter that lives wicked blow every time, even max attack choice band, and ohkos it handily. That's not even the only mon on this team that can destroy Urshifu, so basically you won't ever lose to an Urshifu if you use this team. Threat eliminated: https://pokepast.es/9af732cb894de51d
