Card Rulings

6/1/2012 This effect reverses the turn order established at the beginning of the game. While the order is reversed, anything that cares about this order (such as determining in what order choices are made) will use the new reversed.
6/1/2012 If the game’s turn order is reversed again, it will return to the default order used at the beginning of the game.
