>>56553253They ban evasion because nobody but a handful of annoying assholes like it. Any format that puts evasion up to a vote inevitably bans it because NOBODY wants to put up with missing 100% accurate moves.
Sleep is only banned in formats where the power level is so high that 1 missed turn can completely lose you the game. Darkrai is a complete shitmon in Ubers without sleep, but in the formats where Game Freak didn't knee cap Dark Void because of fanfic format (VGC), Darkrai is a top 5, sometimes top 3, Pokemon. Entirely because 1 turn of sleep in Ubers can amount to a won game. Gen 9 Ubers is so hyper offensive that 1 turn can mean you completely lose to the plethora of heinous setup sweepers from Dragonite to Zamazenta to Kingambit to Roaring Moon to Iron Valiant to etc.
