Official Rulings for Ixidron
9/25/2006 : If Ixidron and another creature are entering the battlefield at the same time, the other creature enters the battlefield face up.
9/25/2006 : The controller of a face-down creature can look at it at any time, even if it doesn't have morph. Other players can't, but the rules for face-down permanents state that "you must ensure at all times that your face-down spells and permanents can be easily differentiated from each other." As a result, all players must be able to figure out what each of the creatures Ixidron turned face down is.
9/25/2006 : You turn the creatures face-down *as* Ixidron enters the battlefield. There is never a moment when Ixidron is on the battlefield and the creatures are face-up. If a creature on the battlefield has a "whenever another creature enters the battlefield" ability, it won't trigger because that creature will be face down before Ixidron enters the battlefield.
9/25/2006 : Turning a face-down creature face-down typically has no effect; the creature's status is unchanged.
