Idk who should manage the meta but if The Immortal is okay with me, I am considering to ban Transform JUST for AAA Sketchmons because it's obviously a problem right now, especially with Prankster. Or just banning the combination Transform + Prankster.
Normally, in Sketchmons, Transform Chansey is managable because you can Sub or Taunt on it, or even damage it because almost everyone's faster than Chansey. But in AAA Sketchmons, Prankster gives you priority, which makes outspeeding much harder and makes the meta completely centralized on either Imposter proofing or Prankster Sub/Taunt.
And before you say Imposter proofing is easy, no it's not. This meta isn't BH where you can run any moves and any mon with ease. This meta is limited to OU banlist PLUS both Sketchmons and AAA banlist combined. And, you can only sketch one move, not in BH where you can use any move you like. These reasons are why Imposter proofing is significantly harder and basically makes Transform an unhealthy move.
