This deck is a combination of Necrium and Galakrond Rogue using both of the decks' win conditions.

Necrium Apothecary can highroll into a getting a Deathwing, Dragonlord on the board as early as turn 3 or 4 which can then potentially be taunted up against aggressive decks with a Titanic Lackey or just used to smorc a few times for lethal. There is also an Azure Drake in the deck that might get pulled out along with Deathwing, Dragonlord and you could get more dragons off the new Draconic Lackey.

With the help of Galakrond, the Nightmare and Umbral Skulker, you can make some huge Edwin VanCleefs or deal a bunch of damage with Spectral Pillager, especially combined with Spirit of the Shark. Because Rogue's Invoke gives Lackeys, Heistbaron Togwaggle is also included for more 0 cost cards using Wondrous Wand or just dumping a few large minions on the board for tempo with Zarog's Crown.
