Hm, intresting topic, I do have to agree that jirachi's non luck-based sets are still pretty solid in this metagame and it MIGHT be S, it's got a lot going for it, though garchomp is really annoying it to death with that thunder/twave immunity, SE STAB 130 base attack EQ, and 2 point higher base speed, not sure if chomp is enough to scare rachii back into A+, because SD chomp KOs through shuca I believe, regardless, while it may be amazing and stuff, we have to admit it's shit against sun, Sun unless your running non HP Fire venusaur, can deal with this thing, QD volc can beat it pretty easily, Landorus-t who is commonly seen on some sun stall teams can basically just ruin it's day even with shuca, not only that but we have to admit the whole 100 base speed tier not being what it used to be thing IS true. 100 leaves you open to a lot of shit, and that factor should be considered, though after Lando-I was banned, Rachii really thrived, but we still have strong ass fire mons like volcarona, victini and even some other shit you might see on sun and we have shit like lando-t, gliscor (haven't seen gliscor much, but we have to admit people still use it), chomp and more just scaring non shuca + Ice Punch (though bulkier/yache SD garchomps and lando can handle most of those) rachi. Honestly rachi is amazing, but weather it really deserves S rank is really debatable
I don't see much talk about moving victini anywhere, (I don't want S tini lol, now that would be blind fan-boying) so I might touch upon that seeing as it's Special Ebelt, scarf band and even specs/LO special sets thrive in thsi metagame, seriously man, vcreate/blue flare respectively in sun with great coverage like (trick for band and scarftini) bolt strike on physical and amazing moves in glaciate, tbolt, psyshock, focus blast on special, plus pre-vcreate, this shit can actually live hits just like rachi except you know, worse typing defensively and stuff, but hey, the bulk is there.
Also js, Sdef and NP celebi with batton pass are amazing in this metagame, just encouraging the use of a good mon.
