Nice deck. I would personally change Bryan to Ghumbo and Emeth to Nistarok.
This will allow Kolos to get his bonus which can stop GHEIST, Roots, Pussycats e.c.t from annoying him.
Bryan to ghumbo is possible
But Emeth to Nistarok is something i would never do
Drs in DM is something that just steals time and I really need that time
I like Nistarok because he can inflict damage or he can save you if your going to lose. But its a personal choice.
