It's basically the same list used by the Freeze Mage this season, with the addition of Malygos as a powerful finisher. I will not be surprised if this deck is worse than what we already have. Compared to this list this deck has:

+1 Forgotten Torch (More one spell to kill minions and return better)
+1 Malygos (Big threat. Kill me or kill it in one turn)
+1 Cone of Cold (Better than Barrier to stop damage)
-2 Ice Barrier
-1 Pyro (Malygos can do the same thing and more, like kill in one turn, tank dmg, etc)

Malygos will just another way to kill compared to the standard:
Malygos + Frostbolt (one of them reduced by Thaurissam) + 1 Ice Lance (reduced)

1 - No Pyro?Yes. 10 mana per 10 damage is not a good conversion and is always used 2 turns after Alexstrasza. The idea of the deck is to have versatility to kill one turn after it.

2 - No Antonidas?
With the fall of the Warriors Control, we dont need such a large flow of spells to kill opponents. See 1.

3 - No Ice Barrier? Less effective than a well used Cone of Cold most of time.

Possible trades:
+1 Cone of Cold / -1 Loot Hoarder
+1 Antonidas / -1 Malygos (not a Maly mage anymore btw)
