I personaly find that its better to use brick break on pawniwardActually I don't feel as if Pawniard will ever use (or ever need to use) anything other than Swords Dance, Sucker Punch, Knock Off, Iron Head, and maybe Brick Break. Sucker Punch / Knock Off / Iron Head are all extremely necessary for the set; without SPunch priority you can easily get KOd by almost anything faster, and without Knock Off / Iron Head, you lose vital attacking tools that can defenitely cripple and smash your opponent to pieces. Knock Off and Iron Head are just so good on Pawniard that there really is nothing better that you can possibly use. Swords Dance is also pretty necessary on Pawniard; while it may not always get the chance to set up, once it does, it's a monster, so not giving it that ability really hurts it, imo. Brick Break is much less of a necessity now that Dark-type hits Steel-types neutrally, but you can still use it, I guess (though SPunch + Iron Head are near perfect coverage by themselves now.) Running anything else over those moves is really a waste, in my opinion, because they're are just so good and give Pawniard everything it needs to succeed already. Substitute is cool and all but Pawniard really has no room for it on a set, nor should it even Sub up as opposed to Swords Dance if given the chance.
This has also been brought up before but I agree with prem in that Gligar is actually not outstandingly powerful. If well played, it has a lot of function and utility both offensively and defensively in the field, but the problem is that it's always just so overcountered by every team that finding situations where you can knock out multiple opponents at once is really rare. The lack of Flying Gem in Gen 6 also really hurts it; it now has to wait for its Berry Juice to be activated or knocked off before it can deal any real damage to Ground-type resists. The popularity of Flying-types such as Murkrow, Yanma, and Vullaby are really hurting Gligar's viability, because without a full power Acrobatics all it can really do is maybe set / remove entry hazards and then leave. Also, an increasing amount of Water-types and Ice-type coverage attackers makes it hard for Gligar to actually set up in the first place, and it receives cutthroat competition from other Flying-types, Fairy-types and Ghost-types as the tier's prime Fighting-type counter, drastically reducing its most prominent niche in past generations.
However, this is definitely again not to say that Gligar is a bad Pokemon; it's still a solid top-tier Pokemon that can support its team in many ways. Unfortunately, it does lack quite a bit offensively, and is finding its niche in the meta shrinking more and more as time passes. Right now, a lot of people really only slap Gligar on their team for hazard control and some sort of speedy offensive support, but in battles it's usually only used to control hazards and use a relatively speedy Knock Off (a job that it also has a lot of competition with.) Gligar's best set in past Generations, Swords Dance AcroGem, is also much less powerful for the reasons above. While Gligar does have a new niche as the best hazard controlling Pokemon in the tier right now, it has lost a lot of what it used to have and is definitely no longer as great as it used to be, in my opinion.
Just as a final metagame statement, I am really content with at least the framework of the current metagame. Although there are things that might (probably) be broken, there are multiple top tier threats and a boatload of middle tier Pokemon to use, so much so that when teambuilding it's impossible to just slap every single top tier Pokemon onto one team and call it a day, since there are bound to be more that you can't use and won't cover by doing so. While the meta still has a long ways to go before being truly stable, I'm glad that we at least have so much more to work with now in comparison to last Generation, where we literally only had like 4 or 5 top tier threats.
As then it doesnt get walled by the rising pawniward usage or carvahhna and can hit somethings harder then knock off/s-punch/iron head can and provides neutral coverage.
