The goal of this deck is to use Shark, Umbral, Sonya, Dancing Sword, and Cheap Shot to fatigue the opponent to death!
Nozdormu has a very strange interaction with the rope in that if you kill him on your own turn your entire turn timer resets.
So, essentially we can continuously kill Noz, Umbral, and Dancing Sword with Cheap Shots because we generate 6 coins each time Umbral is played.
I'm not sure I can really explain this one that well. The combo in the video starts at 14:45.
You also need just about as many Emperor ticks as you can get on Noz. Or just draw Noz off Galakrond.
You don't have to use Dancing Sword. In fact Leper Gnome or Kobold Sandtrooper would probably be easier. Dancing Sword is just funnier!
Extremely challenging and very easy to mess up!
