Intruder Alarm {2}{U}

Enchantment

Creatures don’t untap during their controllers’ untap steps.

Whenever a creature enters the battlefield, untap all creatures.

Mirri was startled by Volrath’s apparition—it had no scent.

Notes and Rules Information for Intruder Alarm:
  • If multiple creatures enter the battlefield at one time, this ability triggers once for each creature. This doesn’t matter much, but it can in some cases. (2004-10-04)
