Promise of Bunrei
{2}{W}
Enchantment
Oracle Text
When a creature you control dies, sacrifice this enchantment. If you do, create four 1/1 colorless Spirit creature tokens.
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.
