I've been running this deck for a week now. I am currently 39-33, level 15-10. Early on I had a lot of success vs. the Gal-Shaman but recently they have been moving too quickly to get out their Galkorond followed by Shudderwok to beat on me while I still have my health pool low. I have losing records vs. Shaman (8-9), Pally (0-2), and Rogue (5-8). All other classes I have a solid win rate.
Following the Shaman nerfs, I don't think they will be a problem any longer. Next up will be the Rogue problem. I think it might be necessary to tech in a silence...and maybe even an acidic ooze. That weapon and buff deathrattle combo is deadly.
Anyhow, it is a fun deck. Thanks for your work.
