General MulligansBarnes you'll always want to keep. Stitched Tracker will help you get to the combo. Freezing Trap, Eaglehorn Bow, and Kill Command will hopefully keep you alive in the early game.
Probably a pretty popular Theorycraft right now is the idea of the Big Hunter. Kathrena Winterwisp is pretty much the catalyst for this deck. It aims (ha) to capitalize on cheating out big monsters with her battlecry, and then using her deathrattle multiple times with Play Dead and Terrorscale Stalker.
An extra thread I’ve added, and am excited to see if it will work or not, is the addition of Abominable Bowman, Barnes, and Seeping Oozeling. The idea here, is that Barnes will hopefully summon a beast, and then it will just die with seemingly no consequence. But, when you add in Abominable Bowman to resurrect a full-sized version, and taking into account the only deathrattle Seeping Oozeling can copy is the Bowman’s, I think it will add in more consistency. Also, it could be cool if Barnes pulled Kathrena Winterwisp early in the game.
Let me know what you guys think in the comments, and if I should take out something or add anything it. Keep in mind that this is being created before all of the cards are spoiled and that I might update it after the set comes out
