In light of my recent loss in the AAA branch of OMPL, I'd like to suggest discussion around the possibility of looking at banning some of the more overpowered Pokemon, as AAA is in a similar state to Sketchmons, being left unbalanced due to the bans from last gen being lifted and not having enough of a playerbase to voice concerns about these overpowered threats.
Threats include, but are not limited to:
Mamoswine - For having 0 safe switchins without being absolutely required to use an ability specifically for it.
Terrakion - For the same reason as Mamoswine, but instead sacrificing priority for setting up
Aerilate/Noivern/Landorus-Therian - The nuclear power being thrown around by just these two mons has hardly any options to prevent them from netting at least one kill, the only counters being specific sets on specific pokemon, Landorus being Unaware Skarmory, and Noivern having RegenVest Magearna. While the counters may be commonly used mons, it's basically unfair to all the other mons that these things are allowed. The reason why I also suggest considering Aerilate itself is because odds are that even if these two DO get banned, alternative Aerilate users will take their place and wreak havoc as well, though it may be a similar case to last gen with having to choose between banning Adaptability or several mons because of Adaptability.
Tapu Koko - This thing is an offense killer, being faster than just about everything except the hyperspeed Mega Evolutions, while also dealing damage on comparable levels to Kyurem-Black. Sure, there are things that can wall it naturally, but it can just do the same as Pheromosa and pivot out to get an even larger edge.
Weavile - Has outstanding STABs that hardly anything can safely switch in on, while also having great coverage options as well, not to mention the ability to trap opponents with the threat of Pursuit, making many matchups a 50/50 as a result, in addition to being able to set up and sweep. It'd be as much of an offense killer as Koko if Tapu Fini weren't as prevalent as it is, as well as momentum.
Victini - Fire spam in general is pretty rough in AAA, but most Fire types require a turn or two of setup in order to become dangerous, while Victini just ignores needing a turn and just nukes things with V-Create, or its alternative coverage moves. It has a wide plethora of moves and potential abilities it can use to make it as equally unpredictable as it is deadly. Realistically, there is nothing that comes in safely that lacks the specific counter abilities of Flash Fire, Primordial Sea, and the less popular Thick Fat.
Xurkitree - It has higher Special Attack than Hoopa-Unbound, the ability to pivot, a Sleep-inducing move, and one of the best setup moves in the game. It's essentially a few speed tiers away from being a hypnotizing Kartana. In AAA, you can basically build it to counteract just about anything you want, having Surge Surfer to take out offense, Mold Breaker to ruin stall, and a whole rainbow of possibilities in other abilities and moves to take on anything else it doesn't already threaten.
Even if none of these suggestions get implemented, I just hope AAA can find balance by the time next OMPL comes around, so that the meta can be a bit more standardized and fair/reasonable to play, as opposed to having to worry about 50 things going around and warping the meta all at the same time. I'd hate to see AAA take the same fall as Sketchmons due to the lack of action :(
I can provide more details and factual justification if needed/wanted
