If you do support it well, Kyu-w can work well under Hail. The team that I used it on is a gimmick team, but sometimes it can pull out some impressive wins. Any ways to make it better would be appreciated, as it's fun to play, but I would never risk using it in a high level tour.

The goal of the team is to use Sturdy Shedinja as a pivot to bring in one of the Slush Rush users. Between them, Kyu-w and Lucario can deal with almost every wall as long as their moves actually hit the foe, which is one of the biggest flaws for this team. The defensive core is designed to handle the threats that would kill Shedinja. That's why I have Misty Surge Chansey, to beat status and weaken Core Enforcer, and double rapid spin support, since Kyurem-w under hail forces out spinblockers. Groudon-p with a z crystal serves as a knock off absorber and also steal stat boosts from MMX if it predicts the Shell Smash (it cannot survive a Stored Power, from the stored power/sunsteel/closecombat/smash set, so those sets are auto-losses if I mispredict). Some of the moves are filler though, like the Skill Swap on Chansey
About the offensive mons, the team is really fun to play, and no one expects double Slush Rush so they often leave n in their faster mons to be KOed. Kyu-w's set is self-explanatory with Leaf Storm hitting hard against Primal Kyogre and forcing it out. It unfortunately cannot remove the Assault Vest variants, but Lucario can, so once I realize that it's AV, I'm still okay. Blue Flare nails Steels, and with the specs boost, severely cripples any who don't have Assault Vest along with the hail damage. Lucario runs Gear Grind mainly to get rid of Mega Audino, and so that Sturdy Shedinja can imposterproof it. Diamond Storm is a nasty surprise for ho-Oh, and Bolt Strike hits non Fur Coat Kyogre.
