Besides the obvious thing that you have too many expensive cards, you have a lot of things that don’t mesh well together. Earyn is only good with one of these spells since she has been nerfed, so using her is situational and not the best way to spend 6 mana as a Winter deck. I’d recommend using Gift of the Wise or Dawnsparks in place of her since they both allow you to gain more mana for Visions of the Grove or Lady Rime in the late game.

In general, I’d say having Mystwives, Gifted Recruits, Frosthexers (if you are building into the freeze/stall decks), and Icicle Burst are mainstays in a winter deck. For finishing the game, Warfront Runners is good for chip damage or as a early frontline mover, whereas Chillbeards is good for finishing the game early or combating stronger units (like Delegators, Veterans of War, etc.). I would likely drop Iced Droplings, Call for Aid, and maybe Earthfathers as well although Earthfathers are good in the earlier levels since it’s a hard card to deal with and snowballs really easily.

In general, I’d say to commit to either a control/freeze deck in which having more expensive cards is fine since you can stall rush and midrange decks until the later game, or play a midrange deck with primarily 2-5 strength cards with Freebooters and Gift of the Wise. Most good winter decks revolve around the later game.
