While a minion has an effect that allows them to play cards that require Discipline(s), they do not actually have those Discipline(s).

Multiple similar effects (e.g. two Infernal Familiar, or Ian Forestal with an Infernal Familiar) cannot be used to meet the requirements of a multi-Discipline card that the minion is missing one or more Disciplines to play.
While using their ability to meet a discipline requirement, they also meet that requirement for any other cards associated with the original effect (e.g. meeting the requirement for Pack Alpha or Muricia's Call also meets the requirement for the Raven Spy employed by that effect).
