Rulings
- If you have only 1 face-down Defense Position monster you cannot activate the effect of Shifting Shadows.
- If you control a monster that is targeted by your opponent's Nightmare Wheel, and you flip it face-down with Book of Moon, and control at least 1 other face-down Defense Position monster, you can activate the effect of "Shifting Shadows". However, afterwards you must tell your opponent which monster is targeted by "Nightmare Wheel".
