Dragon Speaker is begging for Dragon Paladin to be a thing. This deck is trying to build card advantage through cards that replace themselves like Firetree Witchdoctor, Bloodmage Thalnos, Hammer of Wrath and Flash of Light (not to mention the awesome deathrattle from Bronze Herald).
Anti-aggro package: Dragonmaw Scorcher, Cathedral Gargoyle, Wild Pyromancer, Hidden Wisdom.
I may swap a Hidden Wisdom and Divine Favor for silencers. I imagine this deck will play more midrange and try to establish board control–Twilight Drake can get rid of multiple minions especially when healed.
