Early game: You will either want to pressure your opponent with early minions (e.g. Guardian Druid, Galakrond Rogue, Mage, Control Warrior) or control the board (e.g. Paladin, Demon Hunter) while working towards your quest reward.

Later: Right from around the time of finishing the quest you want to look to set up lethal by making a wide board your opponent can't clear or finding a big Unleash. Remember, you are different from most hunter approaches by being able to swing back the game even after losing the board utilizing tons of rush minions. Don't be afraid to let your opponent have the board advantage for a turn while settin up for a powerful move, it us important your resources efficiently. Even if you don't have many cards in hand, topdecking is not the end of the world as even a few token sized minions can be dangerous if you get to stick them on the board.

This is not a Tier 1 or 2 deck, but I have a lot of fun with it and while I don't track the stats, it feels favorable vs. some meta decks like Guard Druid, Galakrond Rogue, Priest (strangely), and is OK agaist Paladin and Mage.
