Grobbulus was unlike the previous few heroes because it was not quickly evident what sort of deck I should use to defeat him. His hero power is to deal 2 dmg to all enemies, and a 2/2 slime is summoned for each enemy that was killed. Luckily for us, he always uses his hero ability at the beginning of the turn; otherwise he would be a lot tougher to defeat.

I eventually settled on a Grim Patron deck and it was pretty fun after you get the combo going. Here’s my deck:

  • Execute x 2
  • Whirlwind x 2
  • Cleave x 2
  • Revenge x 2
  • Armorsmith x 2
  • Unstalbe Ghoul x 2
  • Bash x 2
  • Earthen Ring Farseer
  • Frothing Berserker x 2
  • Death’s Bite x 2
  • Axe Flinger x 2
  • Maiden of the Lake x 2
  • Mogu’shan Warden x 2
  • Tournament Medic
  • Antique Healbot x 2
  • Grim Patron x 2

In my winning game, I played a Patron at turn 5 and another at turn 7. Along with an Armorsmith, it was pretty easy to win after that. Looking at my deck now, there are a lot of cards that were not necessary/helpful, but I didn’t play enough times to optimize it.

I’m sure these heroic heroes were much tougher after Naxxaramas came out, but the power creep makes it much more doable now.
