When this artifact enters, exile all creatures with power 5 or greater until this artifact leaves the battlefield. (Those creatures return under their owners' control.)
Watch Out
ETB trigger, not a cast triggerRules Note
This card's ability triggers when it enters the battlefield, not when it's cast. Effects that double ETB triggers (like Panharmonicon) work here. Countering the spell prevents the creature from entering, so the ETB won't fire.
