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.
