Skilled White Magician was the fourth of the five Duelists of Death whom Aster Phoenix Duels. However, he and Skilled Dark Magician were actually Demise, King of Armageddon in disguise. This is character version of the card, "Skilled White Magician". He is the only Duelist of Death that is a LIGHT monster instead of a DARK monster.
The Skilled White and Dark Magicians Dueled Aster as a team. The only cards seen in their Decks were their own cards, their true form "Demise, King of Armageddon" and "End of the World", although it is unknown which of them played each card.
