This is awesome except Jaqen needs to have crazy assassin powers, not that lame gain life draw a card nonsense. He’s a faceless wizard killer! He needs something like “tap target creature you control and Jaquen: Jaquen deals damage equal to it’s power to target creature. You may only do this three times.” And some shapeshifting ability! For some cost and tapping: “Prevent damage delt to Jaqen from one source.” or something like that.
Also, Jorah needs to be way more badass. The cards should play off of one another too, like rebels, mercenaries, and goblin groups according to their families or alliances in the story. Every stark gets +1/+1 for each other stark in play.
