Ability Edit

Master Thief will swap one random card from the opponent's field to the player's side and replace it with Den of Thieves when there is another Underworld card on the player's field. Den of Thieves removes 4 points from the possessor's score. This ability will only activate once and is removed from the card after activation. The cards will stay swapped for the remainder of the match.
