This deck is from Blizzard’s Off-Meta Spotlight, here’s what they had to say about it:
Many Control Warrior decks typically opt to include only Odd-cost cards so they can have an upgraded Hero Power, but this one takes a different approach. With the infinite value generation of two Dead Man’s Hands, you can outlast every threat thrown in your path and win the game via fatigue. Europe’s Selkr outlasted his opponents to achieve a 60.8% winrate.
Rank 25 meta
Don’t generalize from your rank to other people.
Lulz, fatigue warrior still is pretty gud buddy. Using it atm, got a nice winrate at rank 2 rn.
