Freeze Mage is one of the more interesting decks you can play in Hearthstone, and yet one of the oldest that is still a competitive deck today. the deck is all about stalling your opponent long enough until you have a hand full of powerful burn spells and attack face.
One thing to realize is this deck is Reactive, what I mean by that is Your opponent plays something we react to it. remember there's no need to play a card unless you desperately need too.
This Deck relies on A Combination of spells, I refer to this as Your "Win Conditions".
With the addition of a new card Emperor Thaurissan this opens up a whole new tier of potential "Win Conditions" For Example If in hand we have Pyroblast x1 - Frostbolt x1 - Ice Lance x2 , If we Play the Emperor the turn before It will reduce the cost of our spells by (1) Allowing us to ultimately deal 21 Damage next turn! As a Freeze Mage we will generally always have a full hand!
