Ixidron rulings:
2018-04-27: Creatures turned face down by Ixidron are 2/2 creatures with no text, no name, no subtypes, no expansion symbol, and no mana cost. These values are copiable if an object becomes a copy of one of those creatures, and their normal values are not copiable.
2006-09-25: If Ixidron and another creature are entering at the same time, the other creature enters face up.
2006-09-25: 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.
2006-09-25: You turn the creatures face-down *as* Ixidron enters. 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" ability, it won't trigger because that creature will be face down before Ixidron enters.
2006-09-25: Turning a face-down creature face-down typically has no effect; the creature's status is unchanged.
