Keep in mind Bearon Gla'shear and Diligent Notetaker for potential changes. The diligent may help get more Windchill. I don't think going full freeze shaman will make it, but making a mixte with aggro elemental and freeze can do baeitufll things with a lot of draw and freeze that help going face without losing our minions.

Ideal move with Bolner Hammerbeak is to copy Sleetbreaker.
