  Three eminence abilities are triggered abilities. That creature must be on the battlefield or in the command zone as the trigger event occurs and also as the triggered ability resolves. If the creature is in an appropriate zone as the trigger event occurs but leaves that zone, the ability won’t do anything as it resolves.
