Shadow Phase

During the shadow phase the Shadow player plays minions, possessions, artifacts, and Shadow conditions. It is also the phase during which any Shadow events, denoted by the keyword Shadow in the event's game text, may be played. Each Shadow card that a Shadow player plays has a twilight cost, in the black diamond in the top left corner of the card. twilight tokens equal to this cost are removed from the twilight pool for each card that is played. There must be enough twilight tokens to cover this cost in the twilight pool prior to playing a Shadow card.
