May I ask why banning only hypnosis isn't considered as an option? It serves as a compromise between completely eliminating sleep and still getting rid off those annoying Darkrai and Iron Valiant sets. The move seems to be uncompetitive and lacks significant enjoyment in the metagame. There are no Pokémon in the metagame that rely solely on hypnosis and would lose their niche if it were banned. It is worth noting that Darkrai and Iron Valiant are not excessively overpowered without the usage of hypnosis. On the other hand, implementing a complete sleep ban would negatively impact the effectiveness of Amoonguss, Breloom, and Toedscruel, since spore is not overly game-breaking for them and useful tool to shut down mons. However, I can understand the rationale behind advocating for a sleep powder ban, but Lilligant-Hisui is a lot harder to use than Darkrai and Iron valiant team building wise, because it requires sun to function well and there being grass types, overcoat mons and safety goggles to counter sleep powder and spore. The only negative of a hypnosis ban would be for Ninetales-alola which use the move without using it to set up immediately but it doesn't have to run it. I get that it would be a weird ban because not all mons are broken with it, but couldn't it be banned in the same vein as sand veil, or bright powder in that it runs on rng too much to be good for the metagame.
