Nice post! I almost completely agree with your list, with the only exception being the Dhampir Infiltrator.
I think it's going to be more impactful, as its stats are really good and Sneak is very strong in lower mana games. Having Affliction on a Sneak monster also directly counters Triage and because it has Double Strike it should hit the Affliction very easily.
