This is the Kolento Control Shaman Deck w Arcane Giants he was playing on stream. As Kolento does, he has tweaked the list that is most commonly known as Concede Shaman.
The addition of Arcane Giants gives the deck even more low-cost threats. Control Shaman is a solid deck and isn’t going anywhere for a while, it has all the tools you just need to get past the shaky start against aggro.
