My previous post on decent/underrated pokes in the metagme went well so why not another:
This is the most retardedly underused and underprepared for poke in the metagame. I get the feeling people have just forgotten about barbaracle recently, and focused more on carracosta, which is why it is so underprepared for. Fairly recently people have been using pokes like jumpluff and floatzel as there costa checks (or none if your name is kingler12345), which just get stomped on barbaracle, and bulky grass types (tangela, gourgeist), the more traditional ss checks, have fallen in usage a lot lately. This combined with the fact that the metagame in general is getting more offensive is really suiting barbaracle out, as there arent many ways of revenge killing it outside of bulky mons, and most offensive teams as a bulky poke will run piloswine/pelipper/oe which baracle beats. Setting up isnt too hard considering pokes like cb stoutland and rapidash, along with flying/ground/rock/fire mons like pelipper which it forces out, and barbaracle then has the bulk to tank priorities (even without white herb). At +2 it OHKOs most pokes, and some, like gourgeist, only need a small bit of hazard/chip damage to guarantee the KO, and with white herb it takes like 35-40% from priorities like pawniards sucker punch and poliwraths vaccum wave. It is amazing to see how many teams get flat out 6-0d by this yet it is 56th on usage and only 60% are shell smash! Other than tangela/torterra/gourgeist and scarf raichu or haunter/sawsbuck (if adamant), it is really hard to beat after a smash
Not gonna say too much on this as it isnt too badly underused, but both subnp and all out attacker set are amazing in this metagame. Its coverage is immense and due to the lack of stall/lickilicky i have been running taunt in the last slot. This allows simipour to become a great anti lead as it outspeeds whirlipede at +1 (even though venipede is better but w/e), and it still puts in work throughout the battle thanks to its amazing coverage meaning it has no safe switch ins, and unlike pokes such as poliwrath, it is hard to pivot into resisted hits as it is so powerful. The sub np i like despite the amount of priority in the metagame as it is so easy to force foes out due to its typing and coverage (as well as the other set being more popular)
Fraxure has also been forgotten i feel, and although the CB set isnt too useful as slow wallbreakers tend to be shit, the dd set is amazing. Fraxures bulk with eviolite is surprisingly decent, and dragon has really nice resistances allowing it to set up on plenty of pokes (ninetales, zebstrika, etc) and at +1 with jolly it outspeeds all but ninjask and choice scarfers. Its power is also immense, as dragon tends to be a forgotten type in pu, and the steel types get beaten by low kick, and fairy+ice types lose to iron tail. DD + 3 attacks tends to work best for me, i can see the utility of taunt, but you easily get walled by stuff like mime and togetic without. If this gets to +2 you just lose.
The other relevant PU dragon type. Similar to fraxure, i dont feel like the CB set is as good as it was before, however the spdef set is really good right now. Crunch/Dtail/Rest/Thunder Wave is my favourite set, as i have been using it with random clerics (which are also cool), but you can run sleep talk/taunt in the last slot. Zweilous's main appeal is obviously as a ninetales counter, but it also provides a solid psychic switch in, and a check to other fire/water/grass types due to its amazing typing. I also like to run adamant or some attack EVs as other than poliwrath, there arent many dark resists. It is also a nice way to wear down poliwrath (or piloswine/any bulky pokes) to allow pokes like costa to sweep, as if they know it isnt cb/predict crunch, they take 25% + hazards from dragon tail.
Seriously use barbaracle, it is as good as costa, except less people are prepared for it.
