For those of you struggling to build and ladder, I'm here to offer a handful of sample teams for you to use that I've been harassing the ladder with! With my help, I hope more of you can reach the 1300s and beyond by abusing powerful offense. Enjoy laddering this month!
(click the row of mons to get the Pokepaste)

Rain feat. Specs Walking Wake, Water Quick Attack Ogerpon, and two wallbreakers in CM Rbolt and Booster 4 attacks Iron Hands. Easily my most tested team, and my favorite. Comes with a lot of slashed moveset options if you want variety.

Sun feat. CB Entei, Specs Wake, and Balloon Raging Bolt. Hatterene serves as a pivot, and Treads can get rid of Samurott-Hisui spikes or be an emergency answer to a non-speed boosted Iron Valiant or other Fairy type. Torkoal could use something else other than Spin in the second moveslot, but I lack creativity.

Sticky Webs with SD Encore Ival, Specs Gholdengo, Meteor Beam Jugulis and DD Taunt Gyarados. Iron Jugulis is replacable with a variety of special attackers that better fit what you want to avoid losing to, such as a secondary fire or water resist for Sun or Rain teams, another speed booster, a (physical) ground type for mons like Toxtricity and Zapdos, or others.
and some minor comments on the watchlist:
Fine - Close Combat, Annihilape, and Sneasler are all fine. CC has good distribution but only a small handful of non-problematic mons can make fantastic use out of it (imo the best being Iron Valiant, that mon's real good.) Annihilape struggles with weather and the high amount of mons much faster and stronger than it, but it's a good anti-Webs measure and is good on screens. Sneasler loses to priority and weather teams unless it can find a turn to safely SD, and its STABs blank into any poison type.
Watching - Espathra is very strong and still seems like the same wincon it's ever been, but the influx of strong priority and inability to threaten steels makes it managable. Gliscor is strong and annoying but it doesn't have the speed it really needs to solve most of its problems, fast SD feels like the biggest offender in terms of being a metagame problem but eh. Zama-C is probably the second most polarizing mon on there, sometimes it just wins at round start and other times it switches in and dies almost immediately after to a special attack. Has to choose between more bulk for powerful Body Press or more speed, and it hates making that choice.
Problem - I don't like fighting Urshifu-R, it feels excessively strong in Rain and outside of Rain it's still the same old mon that ignores defense boosts and its own atk drops from Intimidate with crits. It resists Steel and Fire ExtremeSpeed, Bullet Punch from Scizor, and Quick Attack from Rock/Waterpon if it's their secondary type. Even with my love of Raging Bolt on most teams I've been using, it's still a problem when my one okay check to it has to check 2 other mons on their team. I'd be fine with Urshifu going, and potentially rain as well, as fun as it is its VERY strong.
