Card Rulings:Light of Intervention


 * You can activate (flip face-up) this card at any time; it does not need to be activated in response to a Summon.


 * The effect of this card applies to both players, and does not affect monsters that are already on the field face-down. These monsters remain face-down until flipped face-up as normal.


 * While this card is on the field, monsters can be Normal Summoned in face-up Defense Position, and can be the target of "Trap Hole" and will trigger effects like the effect of "Mysterious Puppeteer".


 * While this card is on the field, if a monster would be Special Summoned in face-down Defense Position (such as with "Cyber Jar" or "Nimble Momonga"), it is instead Special Summoned in face-up Defense Position.


 * While this card is on the field you cannot flip a monster face-down with "Book of Moon", "Darkness Approaches", etc.

Unoffical

 * You cannot activate "Book of Moon" while "Light of Intervention" is active.


 * "Light of Intervention" only stops you from Setting monsters. Since the final effect of "Cyber Shadow Gardna" Sets it as a Trap Card, this effect will still happen even if "Light of Intervention" is active.


 * While "Final Attack Orders" and "Light of Intervention" are active, you can Special Summon a monster in face-up Defense Position, but it is immediately changed to Attack Position.


 * The Normal Summon of this card is always considered a Set. If "Light of Intervention" is active, you cannot Normal Summon "Mystic Swordsman LV4" because it can only be Normal Summoned face-down, which "Light of Intervention" makes impossible to do.


 * If "Light of Intervention" is on the field this card cannot be Set and if Normal Summoned in face-up Defense Position it will be destroyed.


 * While the effect of "Light of Intervention" is active, you cannot activate "Ready for Intercepting".
