Two nominations, both a little rough because I'm on my phone.
First, nominating Meloetta to rise to B+ or A- on the strength of its SubCM set. This set can't quite 6-0 stall but it uses bulky waters lacking Phazing and every defensive Fairy as massive set-up fodder, and between Psyshock, Hyper Voice, and Shadow Ball it has excellent coverage all while hitting absurdly hard. Basically, if you've reduced your opposing team to a bunch of bulky special attackers or slow physical attackers then SubCM Meloetta can sweep.
Nominating Nidoqueen to drop to B+ or A-. Mamoswine's drop, Feraligatr's rising usage, and the tier growing faster and more offensive in return means that Nidoqueen simply doesn't have the stones to cut it in this metagame like it used to. Bulky Offense and Balance are seeing drops in usage, Hyper Offense prefers Nidoking's higher Speed, and Stall hates stacking extra Pokemon weak to Mamoswine and Feraligatr that don't at least answer Pidgeot. Roserade challenges Nidoqueen's role as a Toxic Spike setter while also answering Suicune and somewhat answering Mamoswine and Feraligatr.
