Rastakhan's Rumble Guide
This is the deck I played for episode 144 of "Walk to Work - A Mobile Hearthstone Podcast".
To finish off Kabal week, I played the Renolock deck Reynad used to make Rank 1 Legend this week.
Do you think he runs BGH exclusively for the mirror match? I just don't see it. On ladder if you get matched against a Jade Druid, BGH isn't helpful. You kill one Jade, they make a bigger one. I'm running this deck with a couple exceptions. I run Kabal Courier instead of Imp Gang Boss (The fact that you can get Kazakus alone is reason enough in my eyes) and Spellbreaker instead of BGH.
BGH is also great at killing Ragnaros the Firelord and Flamewreathed Faceless, both of which can be problematic for the deck. It's a great catch-all for things that can cause this deck trouble, but isn't by any means a must-have.
