Enchant creature
When enchanted creature dies, its controller loses life equal to its power and you gain life equal to its toughness.
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.
