First time posting something for a cap process, so let's see how this goes.
I Would like to suggest two poison types that I feel would have very good niches in our current metagame: POISON with either FIRE or FAIRY. Both of these dual types offer key resistances to the common fighting stab, U-turns, and fairy stabs that proliferate the OU tier, along with a fantastic immunity to toxic. They also both have the benefit of resisting both stabs of iron valiant and jumbao.
Poison Fairy is definitely one of the more unique typings in the game which originated on galarian weezing. The typing has a very defensive profile. It gives two 4x resistances to Bug and Fighting, while giving normal resistances to Dark, Fairy, and Grass, along with an amazing immunity to dragon. On the offensive side, Poison Fairy is not the best. While it does hit for super effective damage against Dragon, Dark, Fairy, and Fighting (Grass too but it's grass) which are all very relevant types. Unfortunately, both stabs would completely shut down by Steel and Poison. It does hit for neutral on every other monotype though.
This dual typing also has the advantages of being immune to Toxic, absorbing Toxic Spikes, and taking neutral damage from Stealth Rock. The combination also does amazingly into meowscarada.
Poison Fire is a less unique but far more efficient typing. Iron Moth, which shares it's typing, is pretty good in both OU and CAP as a wallbreaker, and mollux has seen great use in the past. It shares one of Poison/Fairy's dual resistances in Bug, and gains Grass and Fairy as 4x resistances along side five other great resistances (Fighting, Fire, Ice, Poison, Steel). Offensively, Poison/ Fire is much better than Poison/ Fairy, as both types are only resisted by Rock. It also hits Steel for weakness, which is great in a metagame full of our favorite scales of justice.
It does have it's own shortcomings however. Being weak to rock means that Boots are weighed a lot more as your item, and melting at any ground move thrown your way is not ideal. It makes up for these by being immune to both Toxic AND Wisp, along with still absorbing Toxic Spikes.
I'll end off on mentioning that Fire/Fairy and Poison/Dragon are my two favorite nominees. Poison Dragon is just fun (poison types ) and Fire Fairy is just fantastic.
