WARNING: THIS IS NOT A COMPETITIVE DECK

Many of you may know the combo that this deck is structured around, though it is easier now with BRM: You clone Sorcerer's Apprentice twice using Duplicates, ending up with 4 of them in your hand. While you hold the 4 of them and Archmage Antonidas, you play Thaurissan to make the Apprentices cost 1 each and Antonidas cost 6 (for a total of 10 mana). Then, next turn you play all of them and cast a spell (that spell has its cost reduced by 4-5 mana so it is possible) and you get a 0 mana Fireball from Antonidas, which will give you another 0 mana Fireball and so on until you kill your opponent.

The rest of the deck is centered around delaying the game as much as possible until you get the combo (basically Freeze Mage). The upside of this deck over standard Freezing Mage is that your combo will kill your opponent no matter the healing/armor he gets. Also, Echo of Medivh is there to replace one of your combo cards in case you can't get it (Sorcerer's Apprentice > Echo of Medivh > Duplicate will replace either 1 Apprentice or 1 Duplicate).

This deck is pretty good against most opponents exept aggro decks (Zoo or Face Hunter) or against decks with a lot of face damage (Mage or Oil Rogue). The game IS winnable in these match-ups but it is a lot more difficult. If you are only playing for fun, you might want to instantly concede when you get a Hunter or a Mage.

Have fun with the deck!
