So I've been messing around with Pokemon Online, seeing what works on a hail team and whatnot. I've been trying to get a good Beartic set going, and here's what I've come up with:
Beartic @ Leftovers
Ability: Snow Cloak
Adamant: 252HP/252Atk/4Speed
-Substitute
-Protect
-Focus Punch
-Icicle Crash
This has been a lot more effective than I thought it was, although Beartic certainly isn't perfect. Sub-Punching with Snow Cloak on really goes a long way when setting it up, and having Toxic Spikes on the field allows you to semi-stall on your own. Nothing really likes eating a Focus Punch at all, and in the event you run into someone slower than you (i.e. Reuniclus) Icicle Crash allows you to try to get some flinch hax in. He does take a great deal of prediction to get the most out of (though that goes for all Pokemon, really), but he's quite capable of dishing out damage and generally being annoying with Snow Cloak.
I'm aware of Abomasnow's awful typing (Going after tyranitar is bad, but it might be able to take a hit from a defensive hippowdon)...
What would you reccomend as a lead?
Abomasnow's a great lead on his own, but I highly recommend you slap a Shed Shell on it. With team preview people are gonna want to send out their Chandelures first so they can easily trap and kill your hail starter from turn one.
The set mentioned in the first post of this thread is pretty solid; it takes advantage of his STAB options while giving him the means to stall if need be.
