Archfiend

According to the Upper Deck website, "Archfiend is a special category of card. Most Archfiends can be identified by their name. Any card with "Archfiend" in the card name, is an Archfiend." This category was officially introduced with the release of Dark Crisis, as a way to standardize the English translation of OCG card names containing "Demon" 「デーモン」.

Since some Japanese cards with names containing "Demon" 「デーモン」 had already been released in the English TCG, they were retroactively classified as "Archfiends", although their official names were left unchanged. These include:


 * A Deal with Dark Ruler
 * Axe of Despair
 * B. Skull Dragon
 * Beast of Talwar
 * Fiend Skull Dragon
 * Lesser Fiend
 * Shadow Tamer
 * Summoned Skull
 * Toon Summoned Skull
 * Wicked Mirror
