Okay, it took me way too long to realise this, but Quagsire is not good. Like, really not good at all. I know it just dropped to B, but I feel like this is still way too high for it, and that it should drop even as far as C+, because in this metagame, with all the powerful attacks flying around, it just cannot cope, especially when you have much better options in Alomomola and especially Slowbro who is just superior in almost every way. The only things it deals with better than Slowbro are electric types (such as Thundurus, Raikou, and MManectric, which I will admit is pretty nice, but stall teams almost always run a bulky grass type anyway so these Pokemon aren't really threatening to most stalla to teh point where you need an extra anwser to them) Bisharp, TTar (though Slowbro can even take scarfed Crunches decently), and DD XZard (who is slipping in relevancy pretty fast) It straight-up loses to every wallbreaker in the tier due to the fact that its natural bulk is just not very good. It is just as much setup fodder as Alomomola, and unlike Mola it doesn't make up for it with insane support (all it has for support is Toxic which literally everything else can do).
I'm probably exaggerating how bad Quagsire is, but the fact of the matter is, even it it does the job of a bulky water okay, and has some perks over its competitors, it's really hard to justify using it over Pokemon who are not just better in most scenarios, but also can be used on more playstyles than just full stall. In that sense, it's a lot like Sylveon, who has obvious palpable qualities over Clefable as a wishpasser, yet who lacks so many of its pros that it becomes pretty much impossible to use over Clefable and make it actually worth it. And Regenerator is one hell of a pro. What Regenerator does it not only extend your longevity, not only let you stall out a lot of attackers, but also give you a safety net in case you take a hit that turns out to be a bit too much. So many times I have seen Quagsire switch in on, say, XZard, while being at around 80%, and take a Dragon Claw from it, realizing it cannot take another, and put its user is a really bad position. If the Quagsire user had opted for Slowbro instead, not only would it have probably been at full when it switched, but he could also have switched out to get some of Slowbro's health back, and then switch back in to take on the XZard again. And for a playstyle as vulnerable to stray crits and random coverage moves as stall, when losing your answer to a Pokemon can give the opponent an automatic victory, you need that safety net, more than you need one for setup (which can be predicted with far more accuracy than say, a crit earthquake).
So yeah, Regenerator is far more valuable for stall than Unaware right now, and you have to try hard to justify using Quagsire in this metagame. I really think C+ is fitting.
Jirachi is really good oml. I genuinely think it can move up to A- since it just deals with so many threats and does it so well, provides great support with Wish, and is just a really massive pain in the ass to face especially if you go against the SubToxic set. It's at least on par with Chansey and Skarm (who are somehow still A-...) as a defensive Pokemon, and it can even run offensive sets like Scarf to boot. It's just a very solid and versatile Pokemon in this metagame, not much more to say.
And yes, I know that both these Pokemon have already rightfully been moved very recently, but now that they've been brought to our attention and have gained some momentum, and have both led to unanimous agreement, it seems like the right time to discuss them even more.
Also, any thoughts about Celebi moving to B+? It hasn't had much discussion, and I still stand by my statement that it's a really good defensive mon which takes hits from both sides of the spectrum really well, walls key threats, provides really good support, and has quite a bit of versatility to boot.
