responses to a few things zzz...
mew -> a. mew is one of my favorite pokemon to use in the tier, and it's definitely very solid, as the taunt + knock off + will-o-wisp combo can be very threatening, plus mew is very threatening to many archetypes, especially defensive and sand offense. it's just kind of hard for me to see in a+ rank. it might as well not even exist against every team with a charizard or talonflame and can often be broken down with sheer force through things like mega gardevoir. things like heatran and gliscor are also very annoying for it, and anything that can get up a sub pretty much is screwing it over. while certainly a very effective pokemon, it's also hard to compare with many of the a+ rank pokemon, which are so metagame-defining and prominent. while it has gained some popularity, i don't think mew is as threatening overall as, say, mega gyarados or mega charizard y or clefable or excadrill. kinda struggling to put all of the 'why' in words but mew just doesn't feel like an a+ rank pokemon to me.
garchomp -> a. originally i kinda thought this was crazy but it makes sense the more i think about it. garchomp is great. it has a threatening stab combo, it has nice utility when it sets up rocks, scarf revenge kills a lot of things, checks a lot of big threats, and bulky enough that it can be damn hard to ko. it can set up sd or use fire blast to bypass skarm. it can run a cool rocky helmet defensive set to take advantage of that nice bulk and set up rocks as well as check a bunch of things. however, the meta has shifted away from it, especially with the rise of landorus-t. landorus-t, especially scarf, directly competes with garchomp for a teamslot. they overlap in a lot of ways, but landorus-t has intimidate and more importantly u-turn, which allows it to keep momentum and gets rid of the crazy mindgames you have to deal with every time the opponent has a ground immunity and something to tank an outrage if you're using scarfchomp. especially with excadrill in the metagame, a big thing landt deals with better, plus then you have knock off which is so useful... it's becoming more difficult to justify using chomp over landt, and with that in mind, it should drop.
mega charizard x -> a+. i've already talked about a bunch in the other thread. tldr can't sweep with all the sand/scarf landt/other stuff around, wisp set is great but even combined zard x isn't s rank-worthy.
mega gyarados moving down is lolworthy. it is probably the most consistent mega pokemon in the ou tier. neither scarf landt, nor sand excadrill, nor any priority is capable of revenge killing it, which is enormous, and it always manages to do something. great power, excellent coverage, and enormous flexibility afforded by the typing switch from its normal to mega form that lets it check or counter many pokemon, such as keldeo, greninja, and landorus, and gives it lots of setup opportunities that can spell the end for many teams. the only real issue for it is that ferrothorn is on a lot of teams, and is a hard stop to it, but this can be rectified via support of teammates like hp fire latis, magnezone, or whatever, and it's definitely not the end of the world. mega gyarados is a solid, safe choice in this metagame that it has the perfect traits to succeed in.
i don't think any of the wallbreaking megas (gard, hera, cham) should move up to a+. the biggest issue i have is that they are easily revenge killed and do have a good amount of checks/can be played around. sure, they are incredible nukes and can break down a lot of defensive pokemon, but they are very one-sided in this respect. none of these pokemon provide much defensive utility for the team, forcing teams to compensate in that they have to cover all the normal things in 5 slots plus the things these pokemon have trouble with like extra coverage for birds, all that, and have very few actual switch-in opportunities which means they rely on double switches and voltturning teammates in many instances, a major limitation. teams built for them can be very effective, but that's the key -- teams must be built around them for them to succeed. these limitations lend me to believe none of the three should rise any higher.
quoting alexander for truth about suicune:
Suicune doesn't deserve the A- rank imo.. it has just 1 viable set (which is the CroCune one) so it's predictable as fuck. In addition to that it's great against just few stall teams (because some runs Clear Smog Amoonguss which it can't break) because against offensive teams, hard hitters like Thundurus or Pinsir won't let it setup more than 1 Calm Mind. Also as I already said on the other discussion, stall teams rly won't be as much as popular as before because of how Gardevoir, Heracross and Medicham are in the current metagame. Def not A- rank material TBH
alexwolf, what you said also holds true:
However, Suicune does rely a lot on Scald burning its checks to outlast them and if this doesn't happen Suicune will most likely fail to sweep, and offensive teams with a lot of strong attackers can usually make Cune's presence insignificant, not to mention the unreliability of RestTalk's mechanics, which make Suicune far from an ideal sweeper.
suicune primarily excels against more defensive archetypes that are significantly less prominent in this metagame. very strong attackers being so common and able to power right through it, and its reliance on chances (scald burn, resttalk to pick the right moves) definitely limit its effectiveness. it is kind of underprepared for, but i've never found it that difficult to account for when building a team, that i need to make such big shifts because suicune is a problem. plenty of good pokemon like keldeo, mega venusaur, thundurus, kyurem-b, amoonguss, psong celebi, mega medicham, mega heracross, latios, cm sp clefable, gk greninja, sub gyarados, mew, breloom, as well as just combinations of multiple hard hitters are often enough to break past it or serve as full stops to it. suicune is pretty good, but b+ is as high as it should go.
