Hey all,
I'm gonna give my thoughts on the metagame and why I believe it's leaning towards an unhealthy chokehold with fairy.
Fairy currently has the tools to deal with most of the type chart without too much deviation from a core. While there's nothing wrong with a type being great, there is a problem when a type has considerable constraint on the metagame as a whole. With the two offenders of mega mawile and fluttermane are the reasons why I believe fairy has unhealthy presence in the metagame.
Fluttermane has an incredible speed and special attack stat that very few Pokémon rival. With the combination of it's great move pool with coverage options such as energy ball, thunderbolt, power gem, and etc. It's set up to be a fantastic wall breaker with a great items choices such as a scarf/specs/lo and sometimes leftovers. Fluttermane is very constricting on teambuilding as of right now, considering that only a select few pokemon can take on fluttermane without much fear. The fundamental problem with fluttermane is even if you know what's coming a lot of the time there isn't much you can do about it, if your team didn't already have designated flutter check to that particular set. Scarf can outspeed the entire unboosted metagame and threaten would be revenge killers, baring priority (getting to that latter). Revenge killing is almost impossible without a bulky resist to whatever it locks itself into. This comes into play that this is only one Pokémon, fairy has 3 options for screens and because fairy has so many great options it can easily pivot into it's bulkier mons. That only considering its scarf if you predict wrong and switch into your bulky special defense mon, because of its massive 135 SPA it easily takes a chunk out of a number of said bulky pivots with the specs set. There aren't many switch ins across the types that aren't of the stall archetype. Not many resists its dual stabs on top of its coverage being able to hit the entire metagame for neutral or super effective damage. It can also set up with a calm mind set if it so chooses to on those fearing either choice locked set. Which isn't as prominent or as it's choice sets its still very threatening nether less once the few checks on select (not each) types can be dealt with. Fairy has the tools to deal with them as fluttermane's best partner in crime is mega mawile.
Mega mawile is one fairy's very viable mega options. Mega mawile supplements fluttermane in it's ability to to break through, most would be problematic to fairy with it's incredible attack stat coupled with Huge power. Sucker punch allows mega maw to bypass would be counters that aren't physical behemoths or resists. Priority abusers such as kingambit would threaten most fluttermane out however, mega mawhile is there to handle it with its vast move pool in options coupled with a single swords dance. Non bulky mons are ohkoed with sucker punch at + 2, and bulky mons are dealt with either one if it's stabs or super effective options. It's very easy for mega mawile to get in and swords dance with the screens support + physical attackers in it's base form with intimidate. The best way of dealing with mega mawhile is burning or killing it before it gets to +2. While burning is a bit more feasible for types that have great will-o-wispers and for certain Pokémon with scald. Fairy has hatterene to bounce back statuses, clefable to absorb them, and or tapu fini to straight up deny them. Fairy is also one of types that can experiment with TR and since its speed stat is very low it can be a primer TR abuser, however this is not a common playstyle. It has the team support to handle would be ways of countering it and problematic Pokémon for it to deal with.
Only select types can handle the combination of just fluttermane and mega mawile. With the team support these types do not have the options to deal with both of them without considerable constraint in the team builder. Fire for example is a type that on paper has a great MU against fairy, however in practice it falls short. The combination of fluttermane being able to abuse sun itself and mega mawile being able to ohkos almost all of fire's scarfers without even having to be at +2. In particular fluttermane is able to remove volcanion a major threat for fairy without fear of its stabs being resisted besides Pyroar (which is a very niche pick only for this particular mon). This much more dangerous than tapu koko who fire has ways of dealing with defensively. I'm not saying because fairy can beat fire without much effort is a reason why its unhealthy. It's the fact that it virtually does that with every type with bare minimum requirement being these two Pokémon is unhealthy.
I believe that right now fairy is the premier type in an unhealthy fashion due to these two mons bolstering an already well resourced type to astronomical heights. With these 2 Pokémon the other 4 are simply there to build around their would be counters. This is leading to an overcentralized game of countering fairy and because it can virtually do whatever it wants with no consequences of its team building and if your not playing this type then your at a big disadvantage.

). This means that any Pokemon trying to abuse the Fire damage boost must account for extra speed on their own. In order to do that they would need help from setup moves or items which waste Sun turns or make them weaker to hazards (which Fire is already very weak to in the first place). Torkoal using Heat Rock means it takes all damage from hazards as well which is not good when it's usually the preferred Pokemon to fill the hazard control role and the one setting Sun for the rest of your team. Now you consider the moves accessible to abuse Sun boosts and the best options have recoil (Flare Blitz) or are not 100% accurate (Fire Blast). Second, the debuff to Water only makes damage neutral in essence which is not game breaking by any means; in the Fire vs Water matchup, even though Rain only has 5 turns, it pressures Fire much more and always forces Torkoal in to change it which is easily abusable, so this this not a problem. Fire also famously has an annoying 6 Slot Syndrome where you want to fit a lot onto 1 team but there isn't enough space; Fire teams also lack the support options that other weathers do, for example Sand's SpDef boost and Snow's Aurora Veil and Def boost. Fire is also much worse offensively than Water; Water having some of the most spammable moves like Liquidations from 
and more. So even though on paper Sun may make some Pokemon like

threatening, in reality it's impact is much less than other weathers.
. The Fightinium Z Iron Valiant when powered by Tapu Koko is decidedly anti-Steel, though Gholdengo with a Z Crystal can be teched to survive Knock Off, Mega Scizor revenge-kills with Bullet Punch, or on the worst-case scenario, bait the Z then deal with the Steel bird. Koko-Val structures are also missing a key mon, so no Tapu Lele or Azumarill can be detrimental for that Fairy team in other matchups.
