13 Minions where u could get value from Luna's Pocket Galaxy seems way to greedy for the meta.

A greedy take on the classic freeze archetype. This deck looks like it melts against anything aggressive.

way too slow to play in this meta if you use this deck expect to always be on defense.

Not a bad looking deck

IMO I'd take off the Pyro and sub in another flamestrike. I'd also substitute those fireballs for frostbolts - you're much more likely to have issues early game and low cost 3 dmg spells are a lifesaver.

Mage has a lot less health/healing options now that DK rotated out along with our 1 cost elemental that gave us armor for spell casting. All we have are neutral minions that can restore a little bit of health, Ice Armor, and Alex. Even if you use the frostbolt to delay a frost nova/doomsayer combo it can still have dramatic health implications late game (leaving a minion on board to deal damage across multiple turns = no bueno). 

Nice take on an old classic. I built a wild dragon mage deck and had it full gold over a year ago. This makes me smile. I'll try this deck out a little bit later today and see if I can come back with how it works.
