I know that this deck build is not new, but i'd like to share this for beginners and f2p player like me that are grinding for gold and shiftstone. I defeated the gauntlet boss several times, Direwood Beastcaller, Gordon Fanatic and Haunting Scream are the cards to win. You have to clear the path to attack face using several removal or the effect of Minotaur Lighthoof.
I don't add Midnight Gale because I don't have it, but it can replace Lethrai Ranger.
Feel free to suggest and comment
