Freezing mage helps you take control easily and beat him. Ignore his minions and its basic first hand to keep a Frost Nova and search for acidic swap ooze and Demented Frostcaller (big saver)! Demented Frostcaller with Frost Nova always freezes the boss so he is a big save! Arcane Giant are better for this deck cause fast drop on their mana and you want em early on board to start killing the boss. I had Frost Nova first turn but of course kept it till turn 4 so i had more spells aboard. Got a bit bit up at first but then took easy control. Enjoy!
