Frost Shaman is weak for now, but looks alright with Elemental Shaman shell.
Got rid of Fire Elemental (lowest winrate card) and Lighting bolt (low winrate too + we swap it for Frostbite, without losing burst potential).
Sleetbreaker perfect new 2 drop to activate 3 mana elementals.
6 spells is enough to confidently summon ~3-4 elementals with Bearon Gla'shear. Other frost/frost support cards are too slow to set up or damages our own board. Testing needed.
Good draw finally Windchill (1 mana 1 card the dream + positive effect).
1 Ice Revenant to flex, since its elemental and will be cheaper with Granite Forgeborn. Can be swapped for Hero card Bru'kan of the Elements if we will meet slower meta.
Looks like solid tier-2 even for high ranks, probably tier-1 contender.
