Promise of Tomorrow
{2}{W}
Enchantment
Oracle Text
Whenever a creature you control dies, exile it.
At the beginning of each end step, if you control no creatures, sacrifice this enchantment and return all cards exiled with it to the battlefield under your control.
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.
