I really enjoy the introduction of hail in this metagame, as it opened up the tier to some more creativity after a time of a somewhat static metagame and no introduction of big threats. Not as they weren't before, but now stealth rocks are an absolute must, especially against hail teams that have at least a couple stealth rock weak mons. With hail teams, I have noticed a heavy decrease in heal bellers/aromatherapy pokes, especially since musharna is not seen as often as it was before (though it can still be effective) and I really haven't seen that many thick fat miltanks surprisingly (use this in ru, but that's besides the point). My last team consisted of a couple t-wave and toxic abusers, which really cripple either fast hail teams, offensive teams in general (t-wave) and hail stall teams (toxic).
Also, even though this little guy might not be around for too long, cb cinccino has really worked wonders in this meta. Especially against hail teams, there are not many pokes that can take a cb rock blast, and it is almost a free move to spam (minus sawks). I believe piloswine is the only poke ice poke that can take rock blast after stealth rocks, and almost kills walrein. The problem with this poke is some ice body pokes carry protect, which further annoys cinccino and racks up damage very quickly, especially since it is so prone to hazards.
Another poke that I really love is specially defensive Probopass, 252/238+/20 speed to outspeed paralzyed ludicolo in rain. Stealth rocks/ t-wave/pain split/volt switch. Can tank choiced locked blizzard spammers, paralyze them, pain split to keep a decent hp, and volt switch for momentum.
I will also be shuckleking__ for all the alts on the ladder
