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.
Watch Out
Exile prevents dies triggersRules Note
'Dies' means 'put into a graveyard from the battlefield.' If a creature is exiled instead of dying (Swords to Plowshares, Rest in Peace), dies triggers won't fire. Tokens do trigger 'dies' abilities briefly before ceasing to exist.
