Having re-read the arguments on Mega Slowbro, I apologise for being brash. Your arguments were totally valid and I was a fool to doubt them. It has left me wondering why is Mega Kangaskhan still banned though?
It is set-up on by common (and relevant) pokemon in the metagame (Mega Sableye, Aegislash, and Mega Scizor are 3 very common examples, which given the size of the tier is more than enough).
It is handled by commonly used defensive pokemon (Sableye, Ferrothorn, Skarmory, Porygon2, Gyarados, Landorus-Therian, Mega Slowbro, Tangrowth).
As well as more niche pokemon such as Spiritomb and Gourgeist.
Set-up sets can be stopped with Taunt. Common Unaware pokemon such as Quagsire and Clefable also beat its set-up sets if it's using ExtremeSpeed as their primary normal STAB (which most sets would)
It is pressured by commonly used offensive pokemon such as Keldeo, Terrakion, Gengar, Garchomp, and Thundurus. And most priority users too...
As well as common scarfers such as Tyranitar, Ditto, and Heatran.
It might seem powerful, but the metagame can adapt and force it to take huge amounts of recoil each turn by simply wearing a Rocky Helmet.
If you're going to be cheeky and mock the council, opening with extreme false humility is pretty obviously fake, even aside from the
bolding.
I still don't agree with the council on Mega Slowbro but your behavior is
highly inappropriate. If they're wrong, they're wrong, trying to sling mud won't prove they're wrong and just reflects badly on your own character. Please stop it.
Re: Mega Gyarados as counter
You do realize Mega Slowbro gets Signal Beam, right? Sure, the set-up sets are probably going to run Scald+Stored Power/Psyshock+set-up and then the last slot will be Slack Off, but they're not the only sets Mega Slowbro can run that are valid -they're just the worst about having a complete runaway effect if you fail to get a counter to them out immediately. Even aside from the more niche Grass Knot, Water/Bug/Psychic is actually surprisingly good coverage, and Mega Slowbro can run it. And since it broadly messes up Dark types, it's even possible Mega Slowbro might run something odd like Stored Power+Signal Beam+Set up+Slack Off and laugh at the idea that Mega Gyarados constitutes a real counter. I'm also not clear how Mega Gyarados is supposed to constitute a counter in the first place, since Dragon Dance Gyarados faced off against Cosmic Power Mega Slowbro will never be able to crit through the defense boosts nor pull ahead of Mega Slowbro's boosting nor wipe its boosts. In fact, completely unboosted Signal Beam is
0 SpA Slowbro Signal Beam vs. 0 HP / 0 SpD Mega Gyarados: 110-130 (33.2 - 39.2%) -- 99.8% chance to 3HKO
so if Mega Slowbro is running that over Scald (Stored Power is too good to give up, really) it will break your substitutes and break
you effortlessly.
Also food for thought: Slowbro gets Drain Punch. Also food for thought: STABmons Slowbro gets
Power Split. Yeah, Mega Gyarados can Crunch up Mega Slowbro pretty reliably -you know, off its 155 Attack, more than double Mega Slowbro's Attack? Yeah, potentially say goodbye to that. Also, Heart Swap. Yeah, these are all more nichedly specific than its
best sets, but they're there, and they're not actually irrelevant, because they make Mega Slowbro that little bit harder to reliably counter.
Also, note that it can just run Miracle Eye over Scald, and now even Dark types aren't safe from Stored Power. Just with two stats maxed Stored Power is 260 BP, so unless you're Metagross or something Miracle Eye ensures an at least 130 BP spammable move -that is, it matches an unresisted Draco Meteor on targets
that resist it. Yeah, Miracle Eye is generally dumb to run, and Mega Gyarados can just switch out -but that gives Mega Slowbro time to heal whatever damage was done and set up more Cosmic Powers.
I'm also just not thrilled in general with the fact that the only thing people have named as a counter to "all" the Mega Slowbro sets (By a very narrow definition of "all") is
itself a Mega. What, are all teams only going to run Mega Slowbro or Mega Gyarados to counter the Mega Slowbros, no other Megas? That's sounding pretty degenerate.
So like I said: not convinced, and not finding the presented logics convincing.
