K.26.1- Cards may include a tombstone icon on the upper left corner of the card, by the card name. [WotC Rules Team 2002/02/01]
K.26.2- This icon has no game effect. It has been added to newer cards to make it easier to identify cards that have an ability that can be used while the card is in the graveyard. [WotC Rules Team 2002/02/01]
