Shadowboxer Combo Deck!!
This deck, can and will win against control as well as aggro. Pyro's combo with cheap spells, such as pyro + shadow d is very good against secret pally (current cancer).
Mullgian is simple, mullgian for your 1 and 2 drops, Pyro depending on the matchup. Hold on to your cards unless you're near sure they won't be removed, such as a turn 1 northshire againt a coin darkbomb or frostbolt.
*UPDATE* [27/10/15] I took out one holy nova because it's sometimes a dead card turns 1-4, and I often wished it to be a circle instead to either buff or clear the board with pryo. So i've added +1 Circle of Healing and -1 Holy Nova
