they are all here, this is gonna be wild
psure zard manaphy and dnite are already bl so they don't count
as for the other stuff
Returning Figures
Ninetales-Alola: Eh, Aveil's not gonna be that great (or at least not as good as it used to), it still lacks a key sweeper in Hawlucha, and if you're familiar with the OU meta you know that thing's not dropping for the foreseeable future, still should be decent
Kingdra: Again, ok I guess, but kinda lacks its full potential w/o Pelipper
Gengar: oh hell yeah this guy's back, gonna be a strong ass special attacker
Newcomers
Marowak-Alola: Due to this coming and Rotom-W leaving, Voltturn's viability will without a doubt be severely hurt, and this mon looks great on its own with options from SD Stallbreaker to Rocks
Lycanroc-Dusk: eh, seems like a neat anti-offense mon, not too sure, but it definitely has potential
Stakataka: Holy shit, this thing's gonna be a monster, once it sets up TR, literally all that can wall it is like Mega Aggron, Quag and maybe super physdef Suicune. There are a fair amount of Ground and Fighting types in this tier, so Staka will probably be a really good late-game cleaner once those are gone
