Not terribly Related, but at 2000 points you can do:
3x Huskard on Thundertusk
1x Frostlord on Stonehorn
1x Icebrow Hunter
1x2 Mournfang Pack
2x2 Frost Saber Pack
All the huskards can heal themselves (or the stonehorn) and it takes some of the melee pressure off of the thundertusks, who do better at range anyway. And stonehorns who heal are just mean
Just a possible alternative to your list that i have had alot of success with.
