Blowfly Infestation
{2}{B}
Enchantment
Oracle Text
Whenever a creature dies, if it had a -1/-1 counter on it, put a -1/-1 counter on target creature.
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.
