hey, cool deck!
i'm not sure about willow and tickatus in the same deck because you can loose the insane battlecry (later in the game you can loose the prime battlecry as well). i am also not sure about demonice studies because your res pool for the prime and n'zoth will probaly get worse
i also would cut nether breath, i mean its a great card but you have only one dragon in deck
didnt think about kelthuzad and cascading disaster. great combo
