Dropping 3 new teams for a post-shellder world.

was a Pokemon I was immediately interested in with the ban of Shellder. Scarf Flare Blitz and Head Smash do an amazing job of either revenge killing or cleaning up games, and now you don't have to worry about a certain someone coming in and clicking shell smash while you're choice locked. Since these are the only two moves you really need that bad, we just throw on Sleep Talk to let it be a viable option to switch into Foongus and eat a spore.

is the standard fast pivot set. It's common for a reason, it's extremely strong and easy to fit on a team. Priority is good. Knock off is good. Pivoting is good. Strong STAB is good. Regenerator is good. Believe it or not, Mienfoo is good.

is, in my opinion, the current best Pokemon in the tier. Not only is any Nasty Plot set extremely threatening, but your opponent also has to guess between not only which Plot set you are, but even if you're running Plot at all, or are you instead a Knock Off/Brave Bird set? This Vullaby, in fact, is a very sneaky Tera Ground Endure set. The team ended up not being amazing into electrics, over relying on Chinchou who is also needed for things like opposing Vullaby, so this surprise option can really help take unexpected kills and go for a full sweep. Not too many other Pokemon fight for tera either on this team, with my 2nd most common one being Growlithe for stronger Flare Blitzes, meaning tera blast is actually pretty low cost to be able to click.

is an excellent glue Pokemon here. It give you access to pivoting, and excellent typing, an electric immunity, and a relatively fast Pokemon that hits hard with strong coverage. This thing will answer most Vullaby sets, can come in on Elekid when needed, and handles more niche threats like Wingull, opposing Growlithe, or Numel.

is great. I love Stunky. I wanted a knocker, I wanted a fast Pokemon, I want a tspikes absorber because I hate glimmet, Stunky's got my back. You're fast, you have the best move in the tier, you have priority, you have an amazing Pokemon that's always going to force a 1 for 1 trade at worst.

may be one of my worst sets of all time. My team lacked hazards, hazard removal, and a consistent priority option (I hate relying on fake out and sucker punch). Rather than rework my team to make it actually good, I decided to force Sandshrew-A to be the glue that holds this team together. And it almost kinda works! Does an excellent job keeping Vullaby in check, revenging, and doing its hazard-related duties. You will frequently think "man I wish I had earthquake rn" however, I fear.
Overall, this team did the job, but wasn't amazing and is definitely the worst of this mini batch. But I think it's very fun to end up in an endgame where Growlithe-H is able to just flare blitz through damaged and/or knocked Pokemon and clean house for you.
Yep, it's screens HO.

sets screens. Dazzling gleam hits Vullaby and Mienfoo which is always good. You can pivot. Very surprising stuff.

loves taking advantage of the screens to be fast, strong, and set up behind a sub when it can. Standard "I want to beat Foongus" set with tera steel, sub, and SD. It's a Mienfoo so it will always be good.

, too, will always be good. This 3 attacks NP set is one of my favorites, Dark Pulse being able to do surprising damage to things like Chinchou or Zorua-H and being an actual consistent 100% accuracy move. Despite that, 3 of this team's 4 losses came on the back of air slash misses when I had committed to a Vullaby sweep. Very sad.

surprised me a LOT on this team. I honestly though this flame charge stockpile set was too much of a meme, but behind screens, you can really set up and spiral things out of control, especially if you're willing to commit your tera to the camel. This team admittedly fought lots of low ladder players because the ladder was dead (hence 28-4 only getting me to 1400), but man does Numel just dominate down there. Be weary of ghost types that force you to use your horrible attack stat to click flame charge and any encore guys, and pray for no crits.

is here because I realized that I do not have a way to clear tspikes, and I wasn't going to find a way to fit a poison type. I hate glimmet with all my heart, so this will not do. Thankfully, Minccino is actually pretty competent behind screens, its speed letting it do its main job of keeping hazards from piling up too high, and life orb tail slaps letting it do its secondary job of killing a lot of stuff. You OHKO Mienfoo after a boost, outspeed and OHKO Weak Armor Vullaby without one, and generally do a lot of damage to everything.

was another Pokemon that surprised me. Obviously we all know Trapinch is strong as a trapper, but screens provided it with the bulk to really unlock its full power. Trapinch is going to be able to handle usual targets, like Elekid or Tinkatink, freeing up good spots for some sweepers (notable Vullaby appreciates those 2 being gone a lot), but behind screens it can 1v1 most Pokemon in the tier. You take under half from a Chinchou's Hydro Pump and OHKO with EQ, for example. Trapinch also acts as the team's only priority option with both First Impression (boosted by Tera Bug if you need it), as well as Feint if 1 priority option doesn't get the job done.
This team was thrown together in like 10 minutes just to see if I could run a Shellderless HO team, and I'm happy to say I am pleased with the results. There are some obvious flaws, it lacks a spore absorber and Wingull treats the team like an all you can eat buffet, but every threat on this team feels very strong and I think there's a reason I saw such good success with it on the ladder, even if it was so dead I didn't want to continue any further.
Okay, I lied about being post-Shellder. This team, while not using Shellder, was built with the idea of using Koffing to check it, taking advantage of Neutralizing Gas to break its skill link and hard wall the now-banned monster. However, I do believe that outside of changing some Tera types, the team will still perform very well.

was the Pokemon I wanted to build around. This team was created during the Shellder suspect, and I really wanted to try every niche answer to it I felt was maybe underexplored in the metagame. With Tera Water and Neutralizing Gas, Koffing handled every Shellder set except for Tera Blast Electric very well. Thunderbolt gave it a way to deal good damage, while also providing use against other threats such as Vullaby and Mareanie. Where Koffing really surprised me, though, was just how good it was into Mienfoo. You resist HJK, have strong physical bulk, spread burns, and very notably, shut off Regenerator. The ability to actually keep Mienfoo chipped for the rest of your team is very appreciated, and I really liked just how much value Koffing was able to get in every game by simply coming in on Mienfoo and clicking wisp to cripple whatever comes in. Pain Split kinda sucks in LC, but I still found it more useful than other options for the last slot like Memento or Fire Blast. If nothing else, a low HP Koffing can chip half of the HP off of whatever it's up against. I tried very hard to justify using Koffing instead of Foongus, who similarly does well against Mienfoo and can use Tera Water to beat Shellder, and I think the ability to shut off problematic abilities and hold its own against Vullaby justified my decision here.

is back to its pivoting ways, still taking advantage of its typing. It's literally the exact same set as above, doing the exact same things.

, too, is the exact same Tera Blast Ground set as above, to very similar success. This team is better equipped to handle electric types, but I found that the set still fits here better than other NP sets, helping the team with issues such as Chinchou and Ice Punch Elekid, who can prove to be problematic despite our own Chinchou and Toedscool.

is stunky. Be fast, click knock off, get a trade at worst, very cool Pokemon.

, speaking of, handles our hazard removal, speads knocks, and is a decently fast option with a good offensive typing. Back in the Shellder era, Giga Drain and tera water were both vital parts of this team, but nowadays I think some experimenting could be done on both options, potentially playing around with DGleam/Spikes/Spore as a moveslot option. However, hitting Mudbray for x2 damage may be reason enough to keep Giga Drain here.

rounds the team out, filling the role I really wanted of a priority option with decent longevity. This set was entirely stolen from a xonks post earlier in this thread, and it works very well. Bulk Up + Drain Punch combo together to provide strong damage boosted by Iron Fist, Ice Punch helps against Foongus (a Pokemon this team does not particularly enjoy seeing), and Mach Punch is a boosted STAB priority option, making it an excellent revenge killing option. Knock Off could have an argument over Ice Punch here, giving the team a third knocker and stronger option into ghost, but I preferred the better option against Foong, Vullaby, and Mudbray.
This team was definitely the best of this bunch, and actually got some good wins against high ladder players, including some against the top 10. I haven't taken the time to play around with it in a post-Shellder world, but I really think that outside of some tera changes, the team should be just as good as it was with the little guy around.
