This deck is a lot of fun, with many different win conditions. The idea of the deck is to buff up your Mana Wyrm in the early game while you are keeping the board under your control with cards like Arcane Blast, Arcane Missiles, Frostbolt, Forgotten Torch and Flamewaker. Your Mana Wyrm is growing with every spell you cast and while your opponent finds it hard to control the board you can deal some sweet damage to your opponents face. Every spell you casts also enpowers your Yogg-Saron, Hope's End and lowers the cost of your Arcane Giant. Both of these cards puts up a win condition in the late game together with Ragnaros the Firelord.
In the mid-game your Faceless Summoner is a key, it can both take care of your opponents board and deal some damage to face. If you somehow lose the board control the Flamestrike will be useful. Try to save your Fireball and Roaring Torch spells to the face if so is possible. The key to be successfull with this deck is to know when to burst your opponent with face damage and when to remove your opponent's minions. I've been really successfull and i've had a lot of fun with this deck so far. It's not really a hard deck to play. I wish you luck and hope that you'll enjoy this deck.
