Mulligans
Shaman
The Lich King start spell sets all shaman’s minions to 1/1.
So here is my custom standard deck.
Strategy:
Mulligan: Unite the Murlocs , Primalfin Totem , Call in the Finishers and Murloc Warleader was good for me.
Use Feral Spirit to protect some murlocs and keep trading them to get an almost clear board at turn 6.
At turn 7 use Devolve over the six “Trapped Souls” so “Frostmourne” weapon gets destroyed, then Cult Apothecary for heal and Lightning Storm for board clearing.
Now Doppelgangster combo with Evolve
Then Thrall, Deathseer plus Bloodlust for quick finish before Remorseless Winter kills you!
