I did pretty well with Freeze Mage. I almost beat him on my first try since I was able to keep Antonidas on the board for several turns in a row. It got to a point where I was holding 10 cards, six of which were Fireballs. I couldn't get new cards in hand, because every time I played a card, it just got replaced with a Fireball, so my freeze spells and board wipes got milled. I would've been able to keep the board clear with all the Fireballs, but he rolled 3 fucking Spellbenders. I wound up getting lucky 2 games later when he pulled Jaraxxus from an Unstable Portal and just wasted all his health and armor.
