Original Idea from reddit: Crazy idea for a metagame: "Shedinja'd." Unplayable or just plain old insane? : stunfisk (reddit.com)
Every pokemon has their HP brought to 1, and magic guard alongside their usual ability.
Mold breaker does not break wonder guard, just the other ability.
Because of potential stall wars, after 40 rounds the player with the most pokemon wins.
Clefable and Alakazam, because magic guard. Sigilyph is much more managable to deal with, so that's allowed.
Sturdy, for obvious reasons.
Maybe a sandstream/hail ban? Not completely sure.
Questions for the Community
Would ubers break this metagame?
How fun would a meta like this be?
This actually a very interessant idea that was developped in last gen thread (by myself
and by Ho3nConfirm3d
So the premise is: every Pokémon has one single HP and can only get hit by super effective move. The 40 rounds is arbitrary and shouldn't exist to start with, there is already an 1000 turns rule on PS! and seeing how easy it is to get a KO and lure something, I doubt the metagame would be to stally.
I don't know why you'd look at Clefable and Alakazam differently than Sigyliph or any Magic Guard user. Magic Guard is centralizing in this tier as it lets them wall most options to get a KO (weather, hazards, status, leech seed, ...). I can only see three ways of dealing with Magic Guard Pokémon. First, running Gastro Acid and Worry Seed can catch off-guard a Magic Guard user that would have sponged a status or switch in during hail/sandstorm. Second, Neutralizing Gas works the same way but works better versus hazards. Third, having super effective hit for the Magic Guard users but this is very restrictive as they have different weakness and coverage can easily be predicted since Hidden Power got removed. There is no real difference between Clefable, Alakazam, and Sigyliph in how you deal with them, because it's a Magic Guard problem. So please, don't consider banning Clefable and Alakazam before Magic Guard.
Sturdy shouldn't be quickbanned because indirect damages would be much more important. This means Sturdy users are still vulnerable to extremely powerful strategies like hazards, status, leech seed, weather, sticky barb trick, ...
Snow Warning and Sand Stream will for sure be very powerful but in my opinion far from broken. Between immuned types, Magic Guard, Overcoat, Safety Gogles, Cloud Nine, and self setting another weather, there are counterplay to weather, even if auto-set, thus it's not broken at all.
Ubers also shouldn't be banned because their ban is a result of too good offensive or defensive capacities in standard metagame, but these capacities are useless in a metagame where every Pokémon has one HP.
I think outside of Magic Guard, nothing is worth instantly quickbanning. Sticky Barb and hazards should stay under the radar, but the rest looks fine and to have enough counterplay.
