One more modification: -1 novice +1 acolyte

I´m playin this list with the following modifications: +1 Antonidas instade of -1 Pyro +1 Cone of Cold instead of -1 Blizzard. I dont think that Antonidas is so slow.

Actually Ice Barrier is necessary, and Antonidas give Freeze Mage an additional win condition.

I replace: -1 cone of cold – 1 blizzard – 1 Pyro -1 Novice Engineer
And I add: +1 Flamestrike +1 Antonidas +2 Ice Barrier

I climb to legend with this decklist.

Now Freeze Mage is playing with a Pyro instead of Loot Hoarder. The rest of the list is OK.
