/**

* 702.53. Haunt
|
|
*
|
|
* 702.53a Haunt is a triggered ability. "Haunt" on a permanent means "When this permanent is put
|
|
* into a graveyard from the battlefield, exile it haunting target creature."
|
|
* "Haunt" on an instant or sorcery spell means "When this spell is put into a graveyard during
|
|
* its resolution, exile it haunting target creature."
|
|
*
|
|
* 702.53b Cards that are in the exile zone as the result of a haunt ability "haunt" the creature
|
|
* targeted by that ability. The phrase "creature it haunts" refers to the object targeted by the
|
|
* haunt ability, regardless of whether or not that object is still a creature.
|
|
*
|
|
* 702.53c Triggered abilities of cards with haunt that refer to the haunted creature can trigger in the exile zone.
