Shadow Dragon N'Zoth

Looking for some feedback on this deck. I've been running this the past hour and have gone 8-1 at rank 12 against mages, hunters, and druids and beat them all. They're completely confused on what tactic you're on. The synergy keeps through the entire match. I like to use Shadow Visions to pull Mind Blasts. NO ONE is expecting Mind Blasts. Doing 10-15 for 4-6 mana with a couple large dragons on the board, GG. They keep clearing? Hello N'zoth. Just baited a Deathwing kill with 3 dragons in hand, followed by N'Zoth on my turn 11. Made a Druid quit. FeelsGoodMan.
