Artifact Creature — Robot Artificer
Oracle Text
Whenever another artifact you control enters, create a 2/2 colorless Robot artifact creature token. This ability triggers only once each turn.
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.
