Intruder Alarm (8ED #86, Rare) is a blue enchantment from Eighth Edition. It prevents creatures from untapping during their controllers' untap steps while granting an ability that untaps all creatures whenever any creature enters the battlefield. This creates powerful token- or creature-entry synergies by turning each creature drop into a mass untap trigger that enables repeated attacker or blocker use and combo interactions.
