A small team dump.
Its been a bit since I've cleaned out my builder and this forum has been dead since like November, so I wanna dump a couple of Poison teams out here for use that I've mostly retired. I don't really have the energy to dig through for replays sorry, but with all Penga teams, they were laddered at a point so they will likely be a few floating around.
Offensive TR GKing:

Concept is simple, TR GKing can work as a decent breaker for Poison. I wrote about what it does in further details in
The Monotype Rising Sets November 2025 edition. Gengar Is chosen as we lack a good way to break steel without EQ on GKing and Scarf Dogi and Steel lacks a good ghost switch in allowing us to potentially muscle through the likes of Corviknight and Heatran. Scarf Dogi is my usually last filler for this sorta team. TR pairs decently well with Poison due to the type's slow nature overall giving us fast Spore/Foul Play with Amoonguss for example.
Weezingless:

For shits n giggles, screw the Ground immunity. Of course it still needs to be built around but by spamming Balloon you've got options. Tentacruel provides removal. Runt is because with Tenta, I don't need pex as much and runt for a potential secondary wincon seemed nice. Air Balloon Sneasler is the main setup guy though. Scarf Glim seemed nice here since Cruel isn't as bulky as pex into fire, espessically Ceruledge, so its a decent way to handle it. Same reason why Rock Slide on AMuk for Volc, That and I already had 3 rounds of Poison STAB that it was easy enough to drop PJab.
Fezandipit Balance:
By far my favorite team here. This came to me while trying to help insertkoin with a Poison team for a tour he was doing with friends. He needed a Poison that could reliably take on Dragon, Dark, and Fairy. Fairy wasn't too much of a concern but Dragon and Dark were. Fez came as a solution to an issue, a check to Raging Bolt and Hoopa-U in one clean slot + Pivot support. I decided to experiment with it myself and it ended up not too bad. Spread outspeeds Modest Hoopa-U. This is also a set I wrote about more in the rising set protect,
The March 2026 edition to be exact. Teamwise, I decided with two Steel weaks on the team, Defensive Moth might be good here so it came onto the squad and since I already had two special walls, fuck it, we can run an Overqwil here. Same reason why I opted for Infest + Surf Toxapex as with 3 alternative ways of spreading Toxic along with Status spreading by every memeber of the team outside of Pex, I went for my funny set. It did far better than I expected it too. Now, Fez probably could be a different set, but I don't care. It was hilarious in action and whenever Calm Mind did pop up and matter, it went hard, notably I know I've lost the replay, but it was able to directly 1v1 a Calm Mind Primarina as it could always outheal the damage it could do with Psychic Noise and was threatening Toxic through Moonblast. Out of all the teams in this dump, this is the one I think has the most legs overall so if you wanna rip it apart and try to build something even better, be my guest, I wish you luck.
