Scizor, Metagross, Hitmontop and Heatran are all solid mons against hail teams, but since no sane person ever runs more than three ice types on a team (even that's pushing it), you should always try to protect this 'mon until the ice types are down. The rest you should probably play as if it were goodstuffs.
