Made this team with ABR for snake but I've been laddering with it a bit in this meta and it's been working out pretty well (peaked #1 at 1803 pts!!). Anyway the main draw was to build around xatu which seemed like a fairly underrated pokemon, useful for walling most (non sd) gliscor & klefki sets as well as providing some useful utility to the team with magic bounce; we gave it protect to get out of choice locked pursuit/knock scenarios & rocky helmet for punishing sr users like ladgron and steelix. After that we decided max def defog scizor would be the best partner for keeping hazards off, capable of beating the pokemon xatu struggle with (such as mamo & terrak). After this we decided to just make it full stall & added the standard core of bliss + alo + quag. As you can see blissey lacks heal bell as we considered toxic + rocks to be more useful (we have an alternative heal beller in altaria anyway). Quagsire is curse to give the team a semi decent win con, as well as walling the plethora of setup sweepers (coba, scizor, altaria etc. you know the drill). Not much to say on the alo set, scald + knock seemed most useful since we appreciated spreading burns & lacked a pokemon with knock off on the team. Last pokemon is max def dd altaria with heal bell; this generally covers the remaining threats such as sd hera & crawdaunt and provides status removal for the team as well as another win con. Main threats to the team would be heal bell + nasty plot toge & most serperior sets, as well as the standard stallbreakers like hera, but they can definitely all be beaten if you play well enough.
Just like to add the only reason I'm posting this is because people are just stealing it and claiming it as their own at this point (fuck miyoka lmao), but it's a good team and has been winning a lot so have fun with it lads.
Hard to find replays of matches on the ladder that weren't just auto wins or boring, but this one vs sacri was pretty decent I suppose:
