I would like to preface this saying that I do not think Charizard Y is bad, just outclassed.
Charizard Y for B+
Let us look at the A Rank definition and see how it applies to Zard Y.
A Rank: Reserved for Pokemon that are fantastic in the OU metagame, and can sweep, support, or wall significant portions of the metagame. These Pokemon require less support than most others to be used effectively and have few flaws that can easily be overlooked when compared to their positive traits.
The first thing that pops out here is the phrase "sweep, support, or wall significant portions of the metagame", which does not apply to Zard Y. It has many more counters than the other wallbreakers in the tier in Lati@s, Talonflame, Heatran, Garchomp, Charizard X, Chansey, and Dragonite and has
way more checks than other wallbreakers. It is unable to sweep or wallbreak most of the tier. His massive amount of checks also mean it can't do its job more than once and is unable to threaten more than one Mon on your opponent's team.
The second thing that pops out is "require less support than most other to be used effectively and have few flaws that can be easily overlooked when compared to their positive traits". Charizard Y REQUIRES Hazard removal and a Pursuit trapper, which eats up 2 of your teamslots just to support a wallbreaker. Not a sweeper, but a wallbreaker who can only do its job one time before becoming dead or useless. It is also restrictive on its user's teambuilding because now you have to take in the possibility of Drought being active when you have your other Pokemon out, meaning you can't slap a Water-type or Fire weak/neutral Pokemon on your team without possible repercussions. This is extremely inefficient.
"But that can't be your only reason to drop Zard Y," you may say. "It hits hard as fuck and nobody can do what it does."
Actually, there are several Pokemon that already do its job. And they are way better.
- Landorus-I
- Keldeo
- Kyurem-B
- Azumarill
- Terrakion
First of all, none of these bar Kyurem-B are weak to SR (Keldeo and Terrakion resist), meaning they can switch in freely and often.
Secondly, all of them have ways of fucking over a switch without much prediction. Lando can Knock Off, U-Turn, or Calm Mind, Keldeo can potentially get a Scald burn, Kyurem-B can set up a Sub and proceed to potentially wreck your opponent, Azumarill can Knock Off or Belly Drum, and Terrakion can use Swords Dance, Sub, Taunt, Rock Polish, or even Stealth Rock. Zard Y needs to predict perfectly otherwise a check comes in and you're immediately forced out while potentially giving your opponent a free Dragon Dance/Swords Dance/Whatever.
Thirdly, none of them require the level of team support that Zard Y does; since the list of things they want dead is small compared to Zard Y. Lando actually doesn't need anything dead as long as it is in front of something that it threatens the fuck out of and lets it start U-Turning/Knock Offing, Keldeo only needs the Latis gone, Kyurem-B only needs Chansey dead (or can kill her itself depending on the set Kube is running) when against Stall or anything faster than it that has super effective moves, Azumarill is only troubled by Mega Venusaur and Amoongus (who are dealt with similarly), and Terrakion is only really walled by Skarmory, Lando-T, Gliscor, and Aegislash without an Air Balloon. What does Zard Y need dead? Thundurus, Landorus, Bisharp/Keldeo/Azumarill/Deoxys-S if you can't get rid of SR for whatever reason, Garchomp, other Charizards (mainly X), Tyranitar, Heatran,
Chansey, Talonflame, Deoxys-S, the Latis, Scarf Excadrill, Politoed, and Dragonite. Wow, that list is long.
Fourthly, none of these Mons are one dimensional (barring Keldeo, who is still hard to deal with thanks to Secret Sword). Landorus can be a Pivot, offensive SR setter, Calm Mind sweeper, and has several coverage options in Sludge Wave, Focus Blast, Earth Power, and Psychic to go along with U-Turn or Knock Off. Kyurem-B can run Physical Scarf or Life Orb, Azumarill can Revenge Kill AND sweep, and Terrakion can sweep, set up SR, Revenge Kill, or even anti-lead. Zard Y has literally one set with massive 4MSS. You need Fire Blast, Solar Beam, and Roost, but have to choose between beating Tyranitar (Focus Blast), beating Heatran (Earthquake),
maybe beating the Latis (Dragon Pulse), or going kamikaze to get rid of Chansey (Flare Blitz lolololol).
Fifthly, these Mons do not have trouble with offensive teams like Zard Y. They have the bulk, power, speed, resistances, coverage, and/or priority to actually threaten many offensive Mons. Zard Y? It's stuck at unboosted Base 100 with no priority, Fire/Grass coverage that cannot be boosted and is easily walled, and has 3 common weaknesses in Rock, Electric, and Water.
Finally,
none of them need Chansey dead to do their job and can actually fuck her hard.
This is the main reason why Zard Y is outclassed, because it is a wallbreaker that cannot break the most common and important wall in the game and has trouble with Stall in general. Landorous has Knock Off, U-Turn, and Calm Mind + Focus Blast to muscle past it, Keldeo just murders you, Azumarill also has Knock off and has been known to run Superpower, and Terrakion can just set up in front of you. The only thing in my list that has trouble with Chansey is Kyurem-B, who can still win depending on the set and fucks Stall over as soon as it gets a Sub up while Zard Y still struggles against several Stall staples such as Heatran, Zard X, and Mega Venusaur (who can stall out the Sun thanks to it boosting Synthesis' recovery).
Onto the B Rank definition.
B Rank: Reserved for Pokemon that are great in the OU metagame. These Pokemon have more notable flaws than those above them that affect how they function in the tier. Their positive traits still outshine their negatives, but they require a bit more team support to bring out their full potential.
Charizard Y fits this perfectly. It is powerful, but flawed and needs support to do its job. You can't slap it on a team like pretty much everything else in the A and S ranks, you have to build your team around it.
TL;DR
Zard Y is outclassed and needs too much support to be considered anywhere A rank; drop it to B+.
I await your hate.
