 I've had minor success with this, in a weird Midrange Mech Mage deck that runs Snowchugger, Clockwork Gnome, Tinkertown Technician, Mechanical Yeti and Kabal Chemist. It works pretty well with Emergency Coolant, and can make use of Freezing Potion from a Kabal Chemist lowroll.

I think this card would actually be playable if it was a 4 mana 4/4, Battlecry: If an enemy is Frozen, gain +3/3 (or +2/2 if that's too op), so that it can be played together with Blizzard.

Does anyone know where to find the full art. I've searched and searched but can't find it!

The wiki usually has it, below the BB code and above the deck statistics there is a "See this on our wiki" link that has the full art.

Did the same for me, I played cryomancer and didn't get the +2/+2

Freezing Potion?

I tried it, pretty dank especially on turn 5

This card will be better in wild and i will try to make him work

The artwork looks really cool.

ICY what you did there ;)

I've had enough of these puns, I'm giving you guys the cold shoulder.

Somehow "5 mana 7/7" just doesn't have the same ring to it...

As if Arena Mage wasn't already strong enough...and not a bad pick for Tempo Mage either. Sure, it might not give you more options for future turns like Ethereal Conjurer or Azure Drake, but the raw stats can give your opponent a run for their money in a lot of cases, especially if you combine this with Freezing Potion.

Shaman has 7/7 for 4 mana, this is potentially 7/7 for 5 mana.. unplayable

Was joking lol

pointless in constructive but probably occasionally strong in arena (because arena mage needed more stuff)

Another reason to run the new potion, Shatter, Ice Lance, oh god Here comes the new meta freeze mage. 

Yeah well except for the fact that this card is not good. And on top of that, Freeze mages only play utility minions for stuff like draw or spell power.
