[Added 9/3] [Hearthstone] The team is investigating reports that Mirage (Spirit of the Badlands) and Fortune (Narain Soothfancy) sometimes generate cards that can’t be played. Some reports are indicating that this problem may be tied to when they transform into a card that generates another card.

Known Issue, they are working on it
