I voted ban in the last Flutter Mane suspect test, and will be doing so again this time. Though I do think people are focusing a bit too much on it in combination with Chi-Yu (which was far from a necessary partner when it was last banned, that duo was way more common pre-Home), instead of on Flutter Mane as a standalone Pokemon.
Flutter Mane, particularly (bulky) Choice Specs, is far and away the best Pokemon in the meta, due to its combination of offensive stats, special bulk, and a typing that doubles great offensively (near perfect neutral coverage) and defensively (two relatively rare weaknesses, one of which is weak to Flutter Mane, and natural Fake Out immunity). I won't retread the same ground from before too deeply, but there is a legitimate question of "what team isn't made better by Flutter Mane", as it's so self-sufficient and does a combination of things so well that nothing else really can. Ogerpon-Wellspring is the Pokemon that comes closest to reaching that same place, but even aside from the limiting factor of Ogerpon-Hearthflame existing, Flutter Mane is on a different level. Wellspring is only a single-target attacker, is vulnerable to Intimidate, and on top of a number of natural checks is practically walled by certain Tera types like Grass and Dragon; meanwhile Flutter Mane has access to a solid spread move and is much harder to slow down offensively. If you want to look at other Pokemon that have recently risen to the top like Chien-Pao or Landorus then you'll find the comparisons also unflattering relative to Flutter Mane for similar reasons. No other Pokemon is as consistently such a threat as Flutter Mane and it isn't close.
It's important to note that while, yes, there definitely are some ways to deal with Flutter Mane, such as Rillaboom, (Assault Vest) Incineroar, and Ogerpon-Wellspring (though it does need Tera to be a reliable check), I don't think that's enough. The counterplay to Flutter Mane is mostly reactive, and while it's not completely unique to say that it's checks can't switch in and take hits comfortably multiple times, the extent to which Flutter Mane can muscle past anything healthy that isn't a dedicated check, or can even get past something that is a check but is weakened, is far beyond that of other Pokemon. Trick Room has also been mentioned, but I don't think that's so simple an answer, as while Flutter Mane doesn't like moving last, it's also easily one of the best Pokemon for stopping Trick Room go up in the first place (especially compared to something else reliant on Speed like Chien-Pao), and historically also fits perfectly onto Trick Room teams as their fast mode (for a current example, look at
the team zee used to win the suspect tour with).
I think this sentence sums up rather succinctly the situation with Flutter Mane, it's so much better than everything else, and warps games (and the meta) around it because of how strong it is. Without Flutter Mane, the meta right now is one of the most balanced in a long time (hence why this suspect test is even happening in the first place), which makes the difference between it and everything else even clearer. Worse Pokemon than Flutter Mane are banned, but nothing close to as strong is legal, and so I think freeing it would be a miI don't know what to vote because I'm really seeing how it's a metagame out of the vgc format switch, honestly it doesn't seem like a threat to me seeing that there is a weak part that is due to his low physical defense performance, things like tera steel iron hands or Ting Lu can be of great help since the metagame would be played around this I feel a slight doubt regarding the voting, will be that flutter mane can be a healthy mon ? Will his defensive quality compensate with his great ability to be a wallbreaker? With these questions I have come to the conclusion that he could be an option to be out of the doubles ou roster but I just like to see something faster and moved in a few turns to my personal taste., es un punto de vista personal llevado a lo subjetivo, pero si al final del caso todo se concuerda en un masivo ban estaría de acuerdo con la comunidad, muchas gracias por leer este mensaje y espero que puedan cumplir sus requisitos ( al leer la descripción de este thread me di cuenta gracias a usuario llamado actuarily que esto es un manera de conectar votos y no un torneo, fui un tonto (。・ω・。)ノ♡. )
