Figured I'd do a minor team dump:
Week 1 vs Teddeh
This is a very basic overpresssure-core kinda team. People often bring really mediocre Tauros checks nowadays, as well, gurdurr is bad in plume meta. Work Up Tauros + Scarf Mesprit mean that you have multiple ways to sorta break through their shared checks, be it setting up, breaking, and then getting hwish'd up, or using Tauros to weaken something like Lix so that Mesprit can clean. Lix + Pelipper is a fantastic defensive core, that, while weak to offensive Fire types, covers a load of other stuff super well. Thief Magmortar is the thing I'm most proud of on this team, and was sorta born from me noticing that all of Teddeh's usual fire checks were very item reliant. Clef is a great mortar check until it loses its Evio, Lanturn is crippled on losing AV or Lefties, Yama really loves AV to actually tank T-bolts well. Finally Boom Shiftry is last to hopefully lure in and KO either Vileplume or Hariyama.
Week 2 vs Chaitanya
This team is not that good, but I saw an old set dump with defensive Smash Omastar, and wanted to build around it as it could theoretically do some cool stuff. Overall I probably should have set up early, but figured Chait was running a Scarf Mesp not a specs mesp, and got punished for that read. Overall this team does not have enough ways to really punish Clef. That said, I do sorta like the concept of spikestack + Swellow + Ninetales, as Ninetales does a great job at weakening the rock type checks to Swellow, as well as Lanturn.
Week 3 vs Lycans
Another overpressure team, again using Mesprit + Normal type. CM HP Fire Mesprit is quite terrifying to face unless you have basically suit skunk, and I did not match into suit skunk. Basic idea is fairly apparent of use HP Fire Mesp to try to whittle Lix and Ferro for Kanga, while using Fog skunk to lure in and whittle Rhydon / Regirock. Its Pup + AV Kanga because I wanted a bit more space vs special threats on the team given that its 0 special bulk rhydon, Scarf Gourg gives a last ditch check to both Hitmon and Samu, Lanturn gives heal bell support which is invaluable for both Kanga and Mesprit given that they're both fairly slow mons.
Week 4 was act
Week 5 vs Soulgazer
The idea here was sorta use Primeape to bring in Grumpig for free on Poison types and then theoretically set up and win. SF Lix helps wiht that by theoretically removing Rotom for you, making it easier, but like, this team did not work that well in practice. The fact that I didn't settle on a team and used something I built quickly really shows with both the team and the quality of the game. Pelipper is forever good, and Suit Tauros again tries to trap Rotom.
Week 6 vs obii
Saw a load of Vileplume usage, and was inspired by a weird SMZU set that I always felt used Regi's stats/stuff better than the parafusion sets. Sub is ev'd to tank both Plume's Sludge Bomb and defensive Lix's everything, though with enough attack Ada Lix can break Substitute. Secret Power is the attack of choice because it doesn't make contact, letting you sorta run through Plume without being just put to sleep/para'd. Speed invest is for base 80s after and base 50s before. Flame Charge Mortar + Stun Spore Plume are the team's counterplay against offense (with Mesprit), and Mesprit also Hwishes Regi cause its good at breaking for itself.
Week 7 vs Goomy
Scarf Lanturn is a weird but solid pick for a team that needed a better Rotom answer (Pyroar ain't enough), actual speed, and really wanted some Heal Bell Support. I expected either Stall or HO from The Goomy, and CM Eball Mesp is part of the team's anti-stall portion, being able to theoretically just run through some stall builds, especially those that rely on special skunk as their like only real Mesprit check. AV Chan is my actual fire/ice resist, because Scarf Lanturn and Pyroar don't count. Curse Lix is something I knew I wanted to try out vs The Goomy since the beginning as it can theoretically just set up at preview vs some HOs, and also can guarantee rocks vs CM Xatu. Taunt Wisp Pyroar is courtesy of Luck, and performs well vs both builds.
Unfortunately scheduling in the finals was very difficult, and games didn't get done. That said I'll post some prototypes.
Jynx + CM Aud
https://pokepast.es/ff3af870f99a33cb
Sash Jynx is great into offense, and I was expecting it from Ren-Chon. CM Aud is a secondary method of sorta trading vs offensive builds, and does a great job at luring in and removing Poisons for Torterra, who may be able to clean. Twave Regi, Peli, Scarf Garb round out the team by providing resists to most of the other required stuff, even if Specs Sprit tears the team a new one.
Retooled Blast Semi-Screens
https://pokepast.es/4f3a100c9a15c1fc
This is a blast team from like ages ago with a few sets swapped. Screens Rotom fits oddly well onto standard Bo builds as it still provides those wonderful resists, Wisp spam, and Volt, Pawniard matches weirdly well into Plume builds, and Gorebyss is forever great. I had Scarf Garb on the brain at this time and it sorta shows.
Smeargle (Georgle?)
https://pokepast.es/5596ece3889f7475
The finals were decided by the time I built this team. Its geomancy Smeargle with wallbreaking support from Scarf Rampardos. This works in theory until you remember that Skuntank, AV Yama, AV Chan, Reg Chan, Samurott, Regirock, Rhydon exist. Still the team did get a couple of wins in tests just cause the rest of the team is solid.
Arbok
https://pokepast.es/f7ca729093a236f5
Arbok is super spicy vs like Lix spammers, esp when you pair it with broken Knock + Turn Mesprit. Idea is basically that you should be able to remove the item of their Lix or Rhydon fairly reliably because people just let you do that, after which point Arbok can pretty trivially set up on their Poison/Fighting/Grass type, and potentially just win game from there. It also basically eats Clefairy by being sorta Status immune while easily forcing it out with Gunk. Yama provides secondary screw bulky Poison support, Scarftom is always useful, and Gastrodon is just fat and brings in Plume. Sorta a weird balance but I love how it played in tests.
