So for those of us who play heartstone, there is a new game mode called dungenon run. Messing around i have discovered that if you pick shaman, take khadgar's scrying orb (your spells cost 1 less) and take unstable evolution, you can use it for an unlimited amount of times wich equals an unlimited amount of fun!:D Hope you try it out and see for your self.
Here is the video:D Have a nice day.
