• Yu-Gi-Oh!: A handful of cards fit this bill.
  • The most classic example is "Swords of Revealing Light," a Spell Card that prevents all enemy monsters from attacking for three turns and flips any face-down monsters face-up. Its original name is "Protective Seal Swords of Light," the first of a series of cards designed to prevent attacking.
  • The picture at the top of the page is a Continuous Trap Card called "Light of Intervention," which prevents either player from Summoning or flipping monsters face-down.
  • "Hoshiningen" is a LIGHT-Attribute monster, one of six Level 2 monsters released early on that boost the ATK of all monsters that share their Attribute by 500 and weaken the ATK of all monsters with the opposite Attribute—this one DARK, obviously—by 400.
  • Then there's "Consecrated Light." A Level 1 monster with 0 ATK and DEF that is nonetheless capable of shutting down entire Decks. With this monster in play, DARK-Attribute monsters can't be Normal or Special Summoned, nor can DARK-Attribute monsters attack if they're on the Field. And kind of superfluously, "Consecrated Light" can't be destroyed by battle with a DARK-Attribute monster, nor does its controller take damage from such a battle.
  • "Barrier Statue of the Heavens" is a monster with 1000 ATK and DEF that prevents either player from Special Summoning non-LIGHT-Attribute monsters. It's one of six Barrier Statues, one for each Attribute.
  • "Jowgen the Spiritualist" is a LIGHT-Attribute monster that bars either player from Special Summoning, period. It can also destroy all Special Summoned monsters on the Field if its controller discards a card.
  • The Equip Spell Card "White Veil" neutralizes all of the opponent's Spell and Trap cards when the equipped monster attacks. It could fit under this trope if you just look at the card itself; the only thing is that the person who used the card in Yu-Gi-Oh! GX falls under Light Is Not Good, which is alluded to with the fact that "White Veil"'s controller loses 3000 Life Points when it leaves the Field.
