My team runs a mega Abomasnow that is capable of sweeping dragons and those three elemental cloud guys that people like to run, but has trouble once the ever-prevalent Heatmor shows up. I was thinking of adding Whiscash to my team as an option to take when my opponent has a Heatmor, but would he be any good for this purpose? He does learn blizzard so he could potentially make use of Abomasnow's hail, though it wouldn't have stab.

I'm also willing to use another Pokemon if there's one that fulfill this job better. Thanks.
