Fun deck.. Frustrating for your opponents!

I don't have Arcane Flakmage but didn't see the point of crafting it with Flamestrike and Flame Ward already in the deck.

Cyclone and magic trick gets you more resources. Often just one spell back in hand will give you something playable.

I believe luna may actually be a weak choice for this deck as I've only gotten to draw with her a couple times across like 8 games.  Considering putting in Power of Creation, Research Project, another Ray of Frost, or even just an Astral Rift as a replacement.

When all else fails.. puzzle-box or Tortollan one out! You will usually end up with a cleared or manageable board, a secret, and several new resources in hand. 

Give it a shot and let me know how to improve!
