- Q: If "Thousand-Eyes Restrict" equips "Sangan"/"Witch of the Black Forest" in face-up or face-down position and makes it into an equip card, will "Sangan"/"Witch of the Black Forest" still get its effect if it is destroyed as an equip or if "Thousand- Eyes Restrict" is destroyed? A: Yes, "Witch of the Black Forest"/"Sangan" will get their effect since they do not have the destroyed in battle requirement.
