This deck is all about heavy control until you can get your discounts through Vanndar and insight going. With the sheer amount of value you get from amulets, discover cards, and N'zoth this deck will go on forever. I have had games where one turn I am 3 health vs Pirate warrior and the next turn I have 20+ life and 16 armor. Play smart and hold your weapons until the right time and this deck will Win for you. Enjoy!
