S -> A+
A -> S
This post has been a long time coming. Zamazenta has been supremely overrated for months at this point, that is something that has been on my mind a while. I however, did not share my opinion until fusien, a player I highly respect and someone who won OST, went to bat for zamazenta as the best pokemon in Overused after I had made the declaration that corviknight was the best pokemon in Overused.
SPL had recently ended and I checked the stats to see if my biases and opinions were purely personal, after all if a good player such as fusien believes it I should take it seriously. I cannot express how shocked I was when I saw the stats. Confirming my opinions more than I had ever dared to imagine. Corviknigtht posted the very best winrate on the list of OU pokemon. Boasting an insane 68% winrate w/o mirror. Meanwhile, Zamazenta is THE WORST in the top 10 most used pokemon.
SPL is supposed to be the most prestigious tour where the best players meet. Yet, all of the tour players just pretended to not notice Zamazenta sucked in the tour? And we are supposed to pretend this pokemon is the best??? What are we the WNBA? Zamazenta is the Angel Reese of pokemon.
I made a video analyzing the SPL winrates of pokemon and went further in depth on Zamazenta and Corviknight's respective performances.
However, my argument goes far beyond just SPL winrates.
Zamazenta simply does not pass the eye or feel test at all as "the best pokemon in OU". Zamazenta is a pokemon with a great many sets that can threaten teams with a bit of variance in answers which makes it versatile. However, Zamazenta is completely blanked in far too many matchups to be seriously considered an S tier pokemon. Pecharunt is a solid pokemon and completely shuts down every single zamazenta set. Corviknight (the best pokemon in Ou rn) shuts down zamazenta's sets bar roar. Idef corv beats idef zenta thanks to helmet unless zenta can crit and 4 attacks is not strong enough. 4 attacks boots zamazenta has to make tough decisions with its coverage options. A variety of landorus, gliscor, moltres, zapdos, gholdengo, clefable, and primarina shut zamazenta down depending on the set. Zamazenta really relies on your opponent to be not great and bring a team with no answer to iron defense zamazenta to truly shine. Those people are growing smaller in number by the day as we have adapted to zamazenta being allowed. I will give zama can pull a game out of its ass with a tera that can beat the opponent, but Dragonite does the whole matchup fishing far more adeptly than the dog.
Obviously every pokemon has a tough matchup or two or they would be banned to ubers. Yet in so many games Zamazenta is just useless. In what game ever played has Corviknight been a useless pokemon? Always does something important in every single matchup. Great Tusk and Kingambit are other worthy contenders for S rank in my mind. Are those pokemon ever blanked on matchup? Could not remember a time I was happy to see a kingambit on the opponent's team, because I had a perfect 100% counter. Great Tusk's utility is important and has to be acknowledged no matter the circumstance, even if it is objectively blanked offensively, its knocks, spins, and hazards have to be contended with.
As for Corviknight, simply the best pokemon in Overused. Corviknight is the absolute hard carry of balance and stall. The premier way to handle meta strong offensive threats such as kingambit, weavile, zamazenta, valiant, and a fair few dragonite sets. What Corviknight does for balance is irreplacable. Who else can take on weavile and kingambit over the course of a long game? Weavile and kingambit are two mons with a complete dearth of long term answers. Brave bird idef press corviknight is perhaps the only pokemon that can trade favorably into them, even if they tera. Corviknight shuts down gliscor, particularly sd gliscor which can be a massive problem for defensive teams, well if the bird knight weren't there.
Corviknight also finds a welcome spot on many offensive teams as a good pivoter. I will not say Corviknight carries bulky offenses it is on, but it is a great role player, uturning on otherwise massive threats so you can bring in your own. Corviknight can hold long enough for your breakers to punch through.
The stats back up Corv the eye test backs up Corv and it sits at A? It is a complete travesty, especially sitting in the same tier as moltres and zapdos, pokemon Corv easily outclasses. Zapdos and moltres do what corv does 100% of the time 30% of the time
I think there is a lot to offer from both posts so I might as well throw in my 2 cents. I do not believe either Corviknight or Zamazenta are S but I do think Zama could be S- and Corviknight can be A+. Both pokemon have plenty of strengths and weaknesses but the thing that I think puts Zamazenta over the edge in viability is the high amount of set variety. Whereas Zama has plenty of variations of both body press and aoa sets, the most Corviknight usually does is choose between its own body press set (which is far less effective than Zama's imo) or using brave bird and u turn. Also, while both pokemon struggle against Gholdengo (who I personally view as a bit overrated but I will not discuss that now) Zama at least has super effective coverage in crunch whereas Corviknight doesn't even have neutral coverage for it. Both pokemon are good but neither are S in my opinion and Zama is slightly more viable.Zama is just about never useless in any game, and insinuating as such just gives the impression there's a bias in your post that you're not admitting, no offense. Beyond just being a potent wincon, it also is a superglue among the tier that soft checks so many threats in one slot which greatly opens up teambuilding. While it's primarily known for being a physical stop, Zamazenta also is able to pivot into threats like special Kyurem in a pinch and force it out, giving its team crucial wiggle room. It's also the best offensive Darkrai check around, and is a great no nonsense stop to various physical boosters in general (especially with Roar, which is a strong set as ever). We've seen all manner of sets come up throughout the generation from various IDBP variants to boots AoA, LO attackers (which offer shocking levels of damage btw and can be difficult to pivot around). Again, it checking so much in one slot eases building which is crucial in a tier notorious for having a laundry list of threats to account for.
I also take issue with the tone of your post which implies that top players are "ignoring how Zama sucked in SPL" which isn't even true, nor would good players ignore it if it were so. Top players aren't too afraid to say when something has a rough spot or just isn't good. This post has somewhat of a matter-of-fact tone that pushes your opinion as fact when it's just opinion. You're plenty entitled to it obviously, but there are better ways to get it across it.
As for Corv, it's pretty difficult to argue it's #1. While it has a number of positives and is doing better than it was in past months, it still faces issues with passivity and being forced into some play loops that are exploitable (taking big enough hits to force recovery which allow in dangerous threats). It also can't really do anything vs the many threats that tech Tera Ghost to handle Zamazenta, who at least can crunch its way past them potentially but Corv has to rely on PP stalling which isn't a guaranteed to function safety net. It also hurts that it's a flyer neutral to fighting in a tier dominated by them, so it has to be more careful with its health so as to not be in range of 2HKOs with SR up.
Corv also doesn't easily outclass either Moltres or Zapdos. While it has match ups it is better into than they can be, likewise they have match ups they're better into than Corv is. While it is SR neutral, it lacks an innate method to punish contact moves it switches into without Rocky Helmet, which is prone to being knocked off, meanwhile Zapdos and Moltres pack deterrents to contact moves with the potential to leave crippling status on them. One is not inherently superior to the other, and simply has to be considered what benefits each bird brings that is better for one's team.
So I think Zama and Corv are fine where they are.
