General changes

Old rule (Ravnica: City of Guilds) New rule (Guildpact)

Haunt

Haunt is a triggered ability. "Haunt" on a permanent means "When this permanent is put into a graveyard from play, remove it from the game haunting target creature." "Haunt" on an instant or sorcery spell means "When this spell is put into a graveyard during its resolution, remove it from the game haunting target creature." A card with haunt typically has another ability that triggers "when the creature this card haunts is put into a graveyard." See rule 502.51, "Haunt."
