"Archfiend", known as "Daemon" (Japanese: デーモン Dēmon) in the OCG, is one of the very first archetypes. Members appear in a myriad of sets due to the string required for inclusion being a simple word in Japanese. While many Duelists use "Archfiend" cards in the anime and manga as a result, only Titan runs a dedicated "Archfiend" Deck. The majority of the monsters in this archetype are DARK Fiend monsters, but there are many monsters of other Attributes and Types.
Some members of this archetype appears as characters in video-games:
- "Summoned Skull" appears in Yu-Gi-Oh! Ultimate Masters: World Championship 2006, Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator and Duel Arena
- "Red Dragon Archfiend/Assault Mode" appears in Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator
- Both "Terrorking Archfiend" and "Infernity Archfiend" appears in Yu-Gi-Oh! 5D's World Championship 2011: Over the Nexus
- Both "Archfiend Heiress" and "Red Dragon Archfiend" appears in Yu-Gi-Oh! Duel Arena.
According to the Upper Deck Entertainment website, "Archfiends are a special category of card. Most "Archfiend" cards can be easily 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 "Daemon" 「デーモン」. Some non-"Archfiend" cards have it spelled "Demon"; for example, the Japanese name of "Regenerating Rose", 「スプリット・
Since some Japanese cards with names containing "Daemon" 「デーモン」 had already been released in the TCG, they were retroactively classified as "Archfiend" cards, although their official names were left unchanged. These are:
- A Deal with Dark Ruler (A Deal with a Daemon)
- Axe of Despair (Daemon's Axe)
- B. Skull Dragon (Black Daemons Dragon)
- Beast of Talwar (Talwar Daemon)
- Fiend Skull Dragon (Death Daemon Dragon)
- Lesser Fiend (Lesser Daemon)
- Shadow Tamer (Daemon Tamer)
- Summoned Skull (Summoned Daemon)
- Toon Summoned Skull (Toon Daemon)
Starting with "Axe of Despair" in Battle Pack 2: War of the Giants, later prints of these cards in the TCG now use archetype conditions in their card text to classify them as "Archfiend" cards. With the release of Legendary Collection 4: Joey's World Mega Pack, all of these cards have archetype conditions classifying them as "Archfiend" cards. In Portuguese, "Archfiend Soldier" also has an archetype condition classifying it as an "Archfiend" card, although this wasn't added until it was reprinted in 2-Player Starter Deck Yuya & Declan.
"A Deal with Dark Ruler" was not included on the original list of "Archfiend" cards that do not have "Archfiend" in their English names on the Upper Deck Entertainment website, as it had virtually no mechanical impact at the time. However, due to later "Archfiend" support it became mechanically significant, so it was given the archetype condition along with the other cards.
The first members introduced after "Archfiend" became an archetype are chess-themed, all of which are named after chess pieces, and feature a chessboard pattern as the background of their artwork.
Since then, other "Archfiends" have been released which lack the chess motifs. In general, they possess demonic and gruesome features, some even going so far as to have physiques featuring bones and sinew reminiscent of their original representative, "Summoned Skull".
Since "Archfiends" have seen many years of release, the archetype has varying appearance themes which change over time. The original unorganized "Archfiends" were generally bony and "horror" themed ("Summoned Skull", "Axe of Despair", "Lesser Fiend", etc.). At this point in time, they were not related other than sharing a word in their Japanese names. Since archetypes were not yet officially part of the game, these early cards were not initially translated as members of a group.
The first archetype-oriented "Archfiends" appeared in Dark Crisis and were chess-themed, each featuring a dice roll-conditional negation of effects that target them ("Terrorking Archfiend", "Vilepawn Archfiend", etc.). These "Archfiends" all had appearances that very closely resembled contortions or variations on "Summoned Skull". This series was the longest-lasting period for the "Archfiends", and provided them with most of their Spell/Trap support, including their first Field Spell, "Pandemonium", and ended with the release of "Imprisoned Queen Archfiend".
The next wave of "Archfiends" appeared in the 5D's period, and had a sports theme ("Archfiend Interceptor", "Lancer Archfiend", "Mad Archfiend"), and for the first time since "B. Skull Dragon" and "Fiend Skull Dragon", featured a Dragon member: "Red Dragon Archfiend". This series had no general effect theme or visual appearance (though skulls featured prominently in several of their artworks), but represented a move away from the "bone and sinew" style of the chess "Archfiends".
The most recent series of "Archfiends" began in the TCG in Starstrike Blast, beginning with the North American release of "Archfiend Empress". These Archfiends bore little resemblance to the original chess Archfiends, having generally purple color schemes, a metallic appearance, and an imperial theme, similar to the "Fabled" monsters. Judgement of the Light introduced the archetype's second Field Spell, "Archfiend Palabyrinth", and the 3000 ATK "Archfiend Emperor, the First Lord of Horror". This support continued in the North American release of Shadow Specters with the release of "Archfiend Giant" which continued with the global release of "Archfiend Eccentrick" in Clash of Rebellions along side the first "Archfiend" Gemini monster "Red-Eyes Archfiend of Lightning" and the retrained version of their first ever fusion "Archfiend Black Skull Dragon".
Building a Deck around the "Chess Archfiends" is tricky since they require your Life Points as payment and paying is not optional. As a result, your Life Points will be drained very quickly, especially since you must worry about further Life Point drain through battle damage from your opponent. Most "Archfiends" do not have enough attack power to hold their ground. Their most useful ability is negating an opponent's effect that targets them by a roll of the dice. However, this is not a reliable defense, and only two of the cards have a 50% chance of negation (although one of them, "Darkbishop Archfiend", works for any of your Archfiends, including the ones that have their own protection), whereas most have a 16.5% chance, and a couple have a 33% chance.
Take advantage of the high ATK of most "Archfiends", namely "Shadowknight Archfiend", "Archfiend Soldier" and "Terrorking Archfiend". "Archfiends" are one of the few archetypes with an abundance of high ATK non-tributers in the game; "Stygian Street Patrol" is an excellent card and can help avoid the Summoning problems usually related to "Terrorking Archfiend". "Summoned Skull" and its retrained counterpart can provide late-game power, as well as receive a considerable boost when used in conjunction with "Axe of Despair" or "United We Stand". If you can weather the Life Point payments, you may be able to destroy your opponent under a barrage of massive attacks. Piercing cards such as "Big Bang Shot" and "Fairy Meteor Crush" can further the punishment, while the "Archfiend's" own innate immunities can provide some defense.
One potential strategy is to use "Foolish Burials" and "Armageddon Knights" to put at least two "Imprisoned Queen Archfiends" in the Graveyard to give "Terrorking Archfiend" 4000 ATK, then banish an "Evil Hero Infernal Gainer" so "Terrorking Archfiend" can attack twice, then play "Checkmate" to allow it to attack directly for a OTK.
"Masked Chameleon" can also be used with "Archfiend Heiress", "Archfiend Cavalry" or "Mist Archfiend" to go into a Level 7, Level 8 or Level 9 Synchro Monster, respectively. "Masked Chameleon" can also be used with "Archfiend Cavalry" for a Rank 4 Xyz Monster.
"Archfiends" are Beatdown Decks that don't rely on Special Summoning, so cards like "Vanity's Fiend" and "Barrier Statue of the Abyss" are great compliments to fend-off Synchros and higher-level monsters. On the other hand, it is very possible to go to the opposite and abuse Special Summoning, both from the Graveyard and the Deck, with cards such as "Archfiend's Roar", "Stygian Street Patrol", and "Call of the Haunted", along with Synchro Summoning higher level Archfiends or fiends to weather down the opponent, such as "Thought Ruler Archfiend", "Chaos King Archfiend", or even "Stygian Sergeants", and very strong monsters that fit with the general Archfiend theme such as "Darkness Neosphere". As an added bonus, the Synchro Archfiends do not require Life Point payment and in case of destruction, "Pandemonium" allows to search the Deck for virtually any other" Archfiend" to take to the hand.
