While it didn’t take me long to beat Gluth (< 5 tries), I didn’t have a good strategy so I think I was a bit lucky. His hero power is to change all of your minion’s health to be 1, and at the same time he has some decent minions including Unstable Ghouls that will wipe out your board. He also has a weapon which is 3/5 but gains +2 for each deathrattle death.

Initially I thought this would be a RNG battle and I aggressively mulligan’d for Acidic Swamp Ooze, although it turns out that in my winning game, he didn’t get his weapon until later (and it didn’t matter). I assumed that my minions wouldn’t stay around for more than one round so I included cheap minions with the highest attack. Here’s my Mage deck:

  • Flamecannon x 2
  • Frostbolt x 2
  • Acidic Swamp Ooze x 2
  • Annoy-o-Tron
  • Forgotten Torch x 2
  • Ice Barrier x 2
  • Emperor Cobra x 2
  • Ice Rager x 2
  • Jungle Panther x 2
  • Magma Rager x 2
  • Scarlet Crusader x 2
  • Wolfrider x 2
  • Polymorph
  • Evil Heckler x 2
  • Piloted Shredder x 2
  • Blizzard
  • Flamestrike

In my winning game, I lucked out by getting Nat Pagle out of my Piloted Shredder, so I was able to top deck faster than Gluth. In a previous game I was one draw away from winning (needed any direct damage > 2). Looking back, I still think this duel is up to RNG and I can’t think of a deck which would give me an advantage.
