If the creature brought into play leaves play, the tracking effect ends and the creature will no longer be removed from game if something happens to the Coffin Queen. [WotC Rules Team 1997/12/18]
If the creature brought into play phases out, the tracking effect continues when it phases back in if the Coffin Queen is still in play. If the Queen left play when the creature is phased out, the creature phases in as normal. [D'Angelo 2000/05/20] See Rule 502.15h.
If the Coffin Queen leaves play or you lose control of it or it becomes untapped, and the triggered ability resolves before the creature comes into play, then the creature will not be removed from the game this way. [D'Angelo 2001/05/19]
Note - This card was creature type "Wizard" until Oracle 2007/10/01, when it became "Human Wizard". Then with Oracle 2008/01/01 it became "Zombie Wizard".
