I really wanted Hero Power Mage to work in Barrens and i hope that the fire tricks Dawngrasp learnt in Stormwind, will help the deck reach a competitive tier.

The new cards provided the class with more defensive options (fire sale, first flame) as well as aggresive (ignite, Grand Magus Antonidas). You try to stabilize and keep the board while slowly dealing some damage to the enemy hero, until you reach the end game and finish with fireballs, Antonidas, Mordresh, or even a buffed up Ignite.

Hero Power can also be used defensively or aggresively depending on the match up and board status. The same goes for Flightmaster Dungar, that can save you with his Heal or close the game after he awakens from his 5 turn nap. The deck also has some card draw options and also includes nobleman, in case you are lucky enough to copy a finisher card.
