I don't know why my posts a week back about Chesnaught got deleted but whatever. As someone that's been pumping it for a while in this thread now, Chesnaught IMO should be at least B, if not B+. From my experience, between Ferrothorn and Chesnaught, the former is better on paper, but the latter is better in practice simply because it's so reliable at what it does. He just makes so many top tier threats fall flat on their faces it's not even funny. Aegislash can't even touch it most of the time. Mega Ttar gets shut down hard. Excadrill gets dominated. Bisharp is basically useless against it. Others like Lando-T, Garchomp, Gyarados, and Conkeldurr do not like fighting this guy either. He can even take on Pokes like Azumarill and Keldeo if you predict properly. Unlike Ferro, Chesnaught has usable offence with 107 base attack, Hammer Arm, EdgeQuake, and Wood Hammer (which I find to be highly underrated on it btw). It can fend for itself with Synthesis, Leech Seed, and Spiky Shield, and it has some very useful support options like Spikes, Roar, and Taunt. Sure it has a bit of 4 moveslot syndrome going on, but whoever you tailor your set to beat, Chesnaught will do it's job.
Another Pokemon that's criminally underrated is Quagsire, I'd move him up to B-/C+ for sure, having it in the same tier as the likes of Rhyperior and Infernape is just insulting for our resident derpfish. There is currently only one Pokemon in the tier that can shut down boosting sweepers than Quagsire and that is Clefable, but the difference between them is that Quaggy's typing allows it to take on mons that it's fairy brethren cowers in fear of, see: Bisharp, Scizor. Having access to a more reliable recovery option (unless Clefable magically picks up Softboiled) doesn't hurt either. While a number of top tier threats have sets that let them get around Quagsire, such as Will-o-Wisp Zard X, if you see that SD or DD go up, Quagsire at least can give you a fighting chance. DD Zard X, Mega Ttar, Mega Scizor, Mega Gyarados, SD Aegislash, Thundurus, Lando-T, Dragonite, Excadrill, and Terrakion are some of the many top tier threats that this thing frustrates to no end.
