This is the Heroic deck I used to defeat Chieftan Scarvash. This fight can be annoying because he starts on board with a Stonesplinter Trogg and Burly Rockjaw Trogg. You’ll want to mulligan for Equality or Doomsayer. If you play Doomsayer and he uses Confuse then you should probably just concede. If you have the Equality and a Haunted Creeper, play the Creeper into his board and the AI tends to break it open which gives you two 1/1s to clear his board with the Equality. After that you’ll just want to keep the board clear and use your spells when they’re available. Argent Commander takes out Ancient Shade and his other 4 health minions. Weapons are good in this battle because his Hero Power doesn’t change their mana cost!
