.. you are able to play more than two Striga (and Maleficia likewise) (pseudo-)discipline cards on an infernal vampire? While the other discipline cards cannot be placed on a vampire with the superior version of the given discipline as per card text, the Striga card lack this text and therefore don’t have this restriction. So, if you have a pile of Striga or Maleficia cards in your hand, you can splash them on your infernal vampires, giving them five or six of these each if want to to.
