Seto Kaiba uses this card during his Duel against Yami Yugi. He summons this card on the first turn of the Duel. Yugi then uses "Queen's Knight" to attack and destroy this card. Kaiba then activates this card's effect to allow both players to Special Summon a Level 4 monster from their hand. Kaiba Special Summons "Rare Metal Dragon" while Yugi Special Summons "King's Knight". The effect of "King's Knight" then activates (since "Queen's Knight" was on the field), allowing Yugi to Special Summon "Jack's Knight".
