Waves of Darkness

When this card is played, Being and Creature
cards on the opponent's field cannot attack on
their turn and if they are tapped, they do not
untap. The effects of this Sorcery last until the opponent summons a Rank IV Forceful Being
card or uses Battle Meditation.
"Debilitating waves of darkness can sap the will of
entire armies that fight the Sith." - Description of
Waves of Darkness in the Jedi Archives
