Tempo Mage (Rise of Shadows)

Try and control the early game with the nice one drop spells. If you have Elemental Evocation+ Mana Cyclone, try and max out on the spells cast that turn. Mana Cyclone will be a zero cost card so use all your mana. on the other hand, if you want to be more aggressive, Elemental Evocation+Cosmic Anomaly makes a nice 2 drop start with some strong 1 drop spells.

Good combo being Spellzerker + hero power and again those 1 drop spells for board clears or an aggressive turn. You could probably switch Spellzerker out for a weapon clear like Acidic Swamp Ooze if you're having problems with a warrior or rogue weapons.
