Looked like that iirc. I think I added Dr. Boom but it doesn't belong there(no BGH Target) and it had 2 Truesilvers.
Kezan is the Techcard you switch with others aka Loatheb, Jones, TBK but since Hunter and Mage are the trend keep it there.
I played around a bit such as testing Holy Wrath, Avenging Wrath(is quiet funny against aggrodecks)
You can win the regular midrange way or screw up your opponent with Consort-->Taurissan when either consecration or Malygos or both in hand.
Then you play Malygos+ Consecration which serves as board clear because there aren't many minions with 8+ HP when on board.
The deck concept is 2-3 months old because we were trying to make other Dragons viable. Malygos turned out to be really surprising because people expect him only to be used in burst decks such as shaman or rogue.
But the 4/12 body is something you shouldn't underestimate.
Warlock, Paladin to be the best ones.
Priest and Mage were okay.
Hunter sucked because Hunter lacks good removal and you killed your opponent far more often with Rag than Malygos.
Others were gimmnicky.
If you want to see other uncopypasted netdecks you should try Asia. They are playing Patron Paladin/Warlock/Priest. They don't burst the opponent down but the Patronsare really sticky.
