Rain 
The combo of Swift Swim + Drizzle is banned, but that's not going to stop us from splashing as hard as we can. We looked at
Drizzle stall when Pex was legal (it still works fine with Mareanie!), so let's see how Swift Swim HO fares.
A triple water core of Barraskewda, Crawdaunt, and Dracovish wallbreaks while complementing each other abilitywise. Liepard's Prankster lets us reliably set rain, and Jirachi's Serene Grace irritates our ladder opponents with Waterfall flinches (and Dark Pulse, and Bite). Tsareena in the back ensures that our 742 speed Skewda doesn't get Mach Punched to death.
How does this team do versus the metagame? In a word, terribly. Dry Skin instantly ends our fun, and Grass types are a huge Ferrothorn in our side. The biggest problem, though, is that this team doesn't have the tools to deal with pretty much any of the tier's anti-HO measures -- Sturdy, Weak Armor, Stamina, Def boosting, you name it and it probably beats the team. Basically the only thing Rain has going for it is that it doesn't lose to Dragapult.
Rating: ★☆☆☆☆
Sun 
Now we're cooking with fire. Unlike monowater Rain sweepers, Sun sweepers come in Grass and Fire type and can hit hard on both the physical and special side. One way to build sun would use Torkoal + Charizard for that sweet Solar Power. I went the other direction with Venusaur.
Venusaur is the fastest flowersaurus in town, and with help from Darmanitan's Sheer Force it can dismantle stall by itself with Fire/Poison/Ground coverage and immunity to Toxic. Roserade functions as Venusaur 2.0 but stronger and faster. Dragapult benefits from Roserade's Technician and Darm's Sheer Force to boost all its moves, and Dragon Darts helps solve the team's Sturdy problem. Liepard and Tsareena were ripped directly from the Rain squad and help us get 8 turns of Vitamin D.
This team gets the Clefable stamp of approval. It's got a ton of threats and ways to deal with all playstyles. The one gigantic weakness this team has is to Flash Fire + Steels -- click x if you see a Chandelure and a Corviknight. Sturdy + Weak Armor is also a toughie to face, especially those Endure Polteageists.
Rating: ★★★★☆
Sand 
Sand dropped off hard after the Sand Rush ban, but Sand Stream + Sand Force is still a potent combination. Tyranitar and Excadrill are both OU pokemon, so I tried my hand at building Tour Player Approved™ sand balance in Shared Power.
Godzilla and the mole is a tried and true core, giving sand, rocks, and spin. I went with Scarf Excadrill for speed control. Hydreigon is an underrated breaker with nice synergies, since Sand Force buffs Flash Cannon and Earth Power and Levitate is very appreciated by TTar and Exca. Ferrothorn + Arcanine gives you a Flash Fire Steel to deal with Dragapult and friends. Sylveon rounds the team out with a Fighting resist and lets Arcanine pick off weakened HO mons with Pixilate Extreme Speed.
I was very pleasantly surprised at how well this balance team works in a tier full of cheesy setup and roided up breakers. Sand chip damage is useful for picking apart flimsy Sturdy teams, and Hydreigon with Wish support pressures stall. Tyranitar counters some classic balance breakers like Reuni and Chandelure. I'm sure some kind of Skill Link offense with Queenly Majesty support could beat this, but I didn't run into it in my testing, so sand balance gets a perfect 5/5 score!
Rating: ★★★★★
I was so inspired by sand that I built an HO version of the team with Sturdy + Weak Armor + Endure sweepers. I think Weak Armor HO is potentially the scariest team around right now. With Sand Force, you're immune to the sand chip that plagues other Sturdy teams, giving you a huge edge in the mirror matchup.
Hail 
Sorry, snow fans, I didn't get around to building with Hail just yet! Stay tuned for more, or build it yourself!
