This deck is a ton of fun, and even very good on account of how the two showcased cards work. Monastery Siege is good with Khans to get started, and awesome with a second one choosing Dragons. Against red and black Dragons is best. Once you control a big critter,Stubborn Denial becomes a Counterspell for one blue, and this is just awesome. I have countered some powerful cards this way.
It is not common to pull off two Monastery Sieges. Here I had one with Khans first, and then the second one with Dragons.
Here is a strong board state. I can counter anything with Stubborn Denial.
