This is the MrYagut Karazhan SMOrc Hunter w Barnes Deck List. When you see Abusive Sergeants and Argent Squires on turn one you know a Hunter deck is built to SMOrc.
I miss the old Face Hunter decks that used to top out at 3 drops and were all face. Call of the Wild is so strong that even as an 8 drop it’s in all the aggressive Hunter decks.
Barnes is in the deck to try and bring a minion with deathrattle to the board, and some extra SMOrc potential.
