Johann Rall's Poker Cards

Origin
Johann Gottlied Rall (or Rahl) was a German colonel, best known for being in command of Hessian troops in Trenton, New Jersey at the Battle of Trenton during the American War of Independence.

Effects
Those who come into contact with the cards will all be compelled to play a game of poker. The urge is so strong that they players will see everything else other than the game as trivial and undeserving of their attention. However, the urge is so powerful that the players will also ignore anything that is a danger, even to themselves, including threats of harm and neglect of personal care.
