This deck is set up to counter most mid game strategies. Always be sure to keep 2 to 4 mana in reserve for dropping assassins or mind control. I find it particularly useful to mind control dougies (return to sender).
Nelly and Terrance for crowd control, Storyteller Jimmy and Program Stan make a good push, along with Sally when the enemy NK is distracted.
Commons and rares are at level 4, epics at level 3.
