Card Trivia:Dark-Piercing Light


 * This card is a strictly worse version of “Seal of the Ancients”, while the latter requires 1000 life points as an activation cost, it reveals all face down cards the opponent controls and not just monsters, and not only that but it doesn’t forcefully activate their flip effects unlike this card.
 * By extension, this also makes it worse that the trap card “Mind Haxorz”.
 * This card’s effect is also basically the same as “Swords of Revealing Light”, without the battle protection.
