Thank you, obviously I shall correct the list accordingly once the Rise Of Shadow set will be released.

*Curse of Weakness

You are right, Taldaram should be considered in replacement of a Dark Possession at least. If you do that, you cannot run Tar Creeper or Lone Champion, anti-aggro tools for the early game. A possible alternative would be the new Curse of Darkness, that can stave off early aggression for a turn giving you time for a Defile or Hellfire.
Therefore, you can update the list this way:
– 2 Dark Possession or -1 Dark Possession + -1 Witchwood Grizzly
+1 Prince Taldaram + 1 Curse of Darkness

We have to wait until 12/4 to experiment the real power of Dark Possession, so in the meantime apply those changes.
