>>38308226With these changes, I expect the following:
Crabominable won't be a common pick, but will definitely rise from the bottom of the barrel, Priority Mach Punch/Ice Shard/Bullet Punch, two of them STAB and some boosted by Iron Fist will certainly help against offensive teams
Abomasnow will become a fierce tank, unleashing devastatng Ice Hammers and Wood Hammers, while being able to take punishment from the physical side rather easily, while also trapping pesky Ice-type weak mons with the Ice type pursuit
Sandslash Alola will become Ice-type Excadrill, it won't be actually as good as him, but will certainly be a scary threat under Hail
Aurorus now hits noticeably harder and also has improved movepool and support options
Glaceon may be one of the most benefited, simply switching it's high defense with Speed, making a speedy ice type attacker with Focus Blast as its main coverage option (I expect other Eevees to also get it), Refrigerate allows for powerful Hyper Voices and Freeze Dry gives it something to hit Water types with (why the fuck it doesnt learn it normally is beyond me)
Beartic's main defect was that it was slow, now it isn't, it will be a extremely dangerous mon under Hail with it's speedy and powerful Icicle Crashes aswell as Earthquake and Superpower as coverage options (Don't expect it to run Ice Hammer though)
Cryogonal got a slight boost to its defense and obtains an option ability, it's main purpose is to rapid spin shit away and that won't change, pick between Levitate or Magic Bounce
Glalie would be a 120 Speed mega with an Ice type Rapid Spin (Changes affect the Mega), it will be immune to Ground before megaevolving too, Ice/Dark to use in tandem with Crunch as its main STAB
Lapras is mostly fine, it just lacks these essential moves for it to support teams properly
