This card now has Enchant Swamp, which works exactly like any other Enchant ability. This means it can only be cast targeting a Swamp, and it will be put into its owner's graveyard if the permanent it's attached to ever stops being a Swamp.
Enchant Swamp
When enchanted land becomes tapped, destroy it.
When this Aura is put into a graveyard from the battlefield, return it to its owner's hand.
