Weather is not the only factor to cause to rise of Abomasnow. Abomasnow is like the most underrated weather inducer... It deserves its OU usage for me. Abomasnow isn't a deadweight despite its Stealth Rock weakness. Hail is super useful for wearing down VoltTurn teams as most of them don't have Leftovers anyway. A couple of Protect users help wear down Life Orb users quickly too. I personally favor Abomasnow's SubSeed set. It's pretty awesome at draining health here and there and wearing down opponents with hail. Still, hail is not easy to use as you have limited choice of teammates so that you yourself don't get worn down by hail too quickly, and having good synergy is no easy feat. Offensive hail teams work too, but I've never really tried it.
Could the rise of sandstorm and hail lead to the decline of Chansey? IDK for sure but Chansey might have difficulty fitting into those teams due to lack of Leftovers recovery.
Also lol. Scrafty and Toxicroak staying OU~ They aren't too bad I think, just that other options (eg Terrakion) are often chosen over it...
