 "'''D/D'''" ({{Ruby|Ｄ|ディー}}{{Ruby|Ｄ|ディー}} ''DīDīDīdī''), known as "'''DD''' " in the English [[Yu-Gi-Oh! ARC-V (manga)|manga ]] and pronounced "'''Double D'''" in the dubbed anime, is an [[archetype]] of primarily [[DARK]] [[Fiend]] [[Monster Card|monsters]] used by [[Declan Akaba]] in the ''[[Yu-Gi-Oh! ARC-V]]'' anime and manga. It is supported by its own sub-archetype, "[[D/D/D]]", as well as the "[[Dark Contract]]" archetype.In the anime, and in the card game, the "D/D" playstyle is a complex, multi-faceted playstyle focused on utilizing almost all summoning methods available in the game, combining long combos of [[Pendulum Summon|Pendulum]], [[Fusion Summon|Fusion]], [[Synchro Summon|Synchro]], and [[Xyz Summon]]ing to summon powerful boss monsters and build impressively strong boards. Secondarily, the "D/D" playstyle involves managing the mandatory self-damage effects of their "[[Dark Contract]]" [[Continuous Spell Card|Continuous Spell]] and [[Continuous Trap Card|Trap]] support cards. Within the archetype, most "D/D" monsters are main deck monsters with weaker supportive monsters with combo-enabling effects, while most "D/D/D" monsters are boss monsters with field-holding effects.In the manga, the archetype has a vastly different playstyle. It lacks the anime version's focus on multiple Summoning methods and managing "Dark Contract" effect damage; instead, it exclusively uses [[Pendulum Summon]]ing, is supported by many manga-only supportive Spell/Traps, and focuses on reducing the [[DEF]] of the opponent's monsters to 0 (reflecting [[Reiji Akaba (manga)|Reiji]]'s obsession with the number zero in the manga) and dealing [[piercing]] damage.

===Appearance===The regular "D/D" monsters seem to be based on different figures and monsters from Western mythology, while the "D/D Savant" monsters are references to great natural scientists from Western history.In contrast, the "[[D/D/D]]" sub-archetype features a distinct design style from the rest of the archetype, with many of its members modeled after famous conquerors from world history.Taken together with its [[Dark Contract|subordinate]] and sub-archetypes, the "D/D" archetype features a mild "business" sub-theme (probably to fit the profession of [[Declan Akaba|their owner]] in the anime), with many support cards referencing elements of modern big business. For example, the "Dark Contract" cards resemble business contracts, and the names of "[[D/D/D Human Resources]]" and "[[Contract Laundering]]" reference the company practices of [[wikipedia:human resources|human resources]] and [[wikipedia:money laundering|money laundering]], respectively. Additionally, some of the archetype's boss monsters such as "[[D/D/D Doom King Armageddon]]" feature a pun in its Japanese name, such as "''Great Des (Death) King''" being scripted as "''Shiiō''", a homophone for "[[wikipedia:Chief executive officer|CEO]]". A similar pun can be found in the Japanese name of "[[D/D/D Oblivion King Abyss Ragnarok]]" and "[[D/D/D Wave Oblivion King Caesar Ragnarok]]", "''Oblivion King''", which is scripted as "''Kaichiō''", a homophone for "[[wikipedia:Chairman|Chairman]]".In the [[Yu-Gi-Oh! ARC-V (manga)|ARC-V manga]], the "D/D" monsters appear to be demons with a mechanical, scientific theme (distinct in design to the "D/D Savant" monsters) and have equipment like scales or microscopes instead of faces.===Etymology===According to [[Sora Perse]], "D/D" is short for "Different Dimension" (ディファレント・ディメンション ''Difarento Dimenshon''), the same as the [[D.D.]] series.<!--Please do not add comparisons with "D.D."; You would be comparing an English name ("D.D.") with a Japanese name ("DD"). Also, "D.D." is ''not'' an archetype.--><ref name="ep12">{{episode|Yu-Gi-Oh! ARC-V|12|ref}}</ref>

In contrast, the ==Members=="[[D/D/D]]" sub-archetype features a distinct design style from monsters tend to vary based on the rest medium in which they were introduced. Two of the archetype, with many of its members modeled after famous conquerors from world history. Taken together with its [[Dark Contract|subordinate]] and sub-archetypes"D/D" subseries, the "D/DSavant" archetype features a mild and "businessD/D Surveyor" sub-theme (probably to fit the profession of [[Declan Akaba|their owner]] in the anime), with many support cards referencing elements of modern big business. For example, have distinct origins from the other "Dark ContractD/D" cards resemble business contracts, and monsters introduced in the names of same medium.* Most "[[D/D/D Human Resources]]" and "[[Contract Laundering]]" reference [[wikipedia:Resource management|like-named]] [[wikipedia:Money laundering|company practices]]monsters introduced in the anime are based on figures from Western mythology.  Additionally, some of the archetype's boss monsters such as "[[D/D/D Doom King ArmageddonGryphon]]" feature a pun in its Japanese name, such as "the only ''Great Des (Death) KingOCG''" being scripted as "/''ShiiōTCG''-original standard "D/D"monster, a homophone for is also based on Western mythology.** The "[[wikipedia:Chief executive officer|CEO]]D/D Savant". A similar pun can be found series, which originated in the Japanese name of anime, are based on famous scientists and engineers.* The "[[D/D/D Oblivion King Abyss Ragnarok]]"/monsters introduced in the ''ARC-V'' manga utilize the "[[D/D/D Wave Oblivion King Caesar Ragnarok]]"to create double-meanings, or just use it to make an alliteration.** The "''Oblivion King''D/D Surveyor"series, which is scripted as "''Kaichiō''"originated in the manga, a homophone for are based on various types of measuring and observational equipment.* The two "[[wikipedia:Chairman|Chairman]]D/D". So far monsters introduced in the ''[[Yu-Gi-Oh!

==Playing style==The archetype's primary play-style is to use the beneficial effects of its various [[Pendulum Monster]]s and "Genghis[[Dark Contract]]" can be used as Synchro Material for  [[Continuous Spell Card|Continuous Spells]] and [[Continuous Trap Card|Traps]] to gain card advantage while also trying to avoid the [[LP]] damage with the effects of "[[D/D/D Gust Oracle King Alexanderd'Arc]]" with , "[[D/D Lamia/D Rebel King Leonidas]]"; these three Monsters can now revive each and be used for two of the most powerful Synchro Monsters called "[[Crystal Wing Synchro Dragon]]", /or "[[Go! - D/D/D Cursed Divine Zero King SiegfriedRage]]" and sometimes , or remove the "Dark Contract"cards from the [[PSY-Framelord Omegafield]]"(after completing the card's combo) with the effects of other members. Managing these cards properly is essential to victory.

Both When [[Normal Summon]]ed, "[[D/D Savant Kepler]]" can [[search]] for any "Dark Contract" card, whereas "[[D/D Savant Copernicus]]" [[send]]s a "Dark Contract" or "D/D" card from the [[Deck]] to the [[GY]]. "Abyss Ragnarok[[D/D Swirl Slime]]" also has a useful effect, from the hand, for loading the GY with revival targets for later, and can [[banish]] itself from the GY on the same turn to [[Special Summon]] any "D/D" monster from the hand. Its GY-counterpart, "[[D/D Necro Slime]]"Kepler, is able to [[Fusion Summon]] by banishing itself and another "D/D" are recoverable monster from the GY, making the duo incredibly useful. Combined with other monsters such as "[[D/D Lamia]]", they can allow for instant usage of [[Synchro Monster]]s too. This leads into using some of the archetype's most powerful combo-pieces like "[[Pendulum EffectD/D/D Flame King Genghis]] of " and "[[D/D Savant Thomas/D Gust King Alexander]]", as well as their [[D/D/D Flame High King Genghis|High]] [[D/D/D Gust High King Alexander|King]] forms (the latter of which also provides a threatening 6000 [[ATK]] [[beatstick]]). Alternatively, this can also grant access to monsters such as "[[Crystal Wing Synchro Dragon]]" and "[[PSY-Framelord Omega]]". However, with the Monster Effect additions of "Thomas[[D/D Berfomet]]" and "[[D/D Gryphon]]" , not only is [[Synchro Summon]]ing easier, but so is the simplest way [[Xyz Summon]]ing, thus granting access to search for a Level 8 not only "[[D/D/DWave King Caesar]]" Monster - who provides great recovery at the end of the [[Battle Phase]] - but also its [[D/D/D Wave High King Caesar|High King]] version and make "[[D/D/D Duo-Dawn Marksman King Kali YugaTell]]", who provide Summon negation (with an ATK boost) and ATK/[[DEF]] ''reduction'' (which turns the downsides of any "Dark Contract" to the player's favor) with the ability to dump any "D/D" or "Dark Contract" card, respectively.

Along with "Zero King Rage", one of the best Pendulum Monsters to place in the [[Pendulum Scale]]s is "[[D/D/D Wave Oblivion King Caesar|CaesarAbyss Ragnarok]]" and , who can easily revive any "d'ArcD/D" were also one monster when another member of the archetype is Special Summoned, at the cost of 1000 damage and the halving of battle damage that turn. Other amazing choices for the earliest ''TCG'' (before Pendulum Scale includes "Alexander[[D/D/D Chaos King Apocalypse]]" and "Genghis[[D/D/D Vice King Requiem]]" were released) combinations used , extending the user's plays and combos while also helping to avoid potential defeats due to abuse the recovery effect of player's own "Dark Contract" cards. "d'Arc[[D/D Dog]]" and can also help immensely by negating the effect effects of various monsters Summoned from the [[Extra Deck]]. Another potent choice is "Caesar[[D/D Savant Thomas]]", a one-card [[Rank]] 8 Xyz Summon - that being "[[D/D/D Duo-Dawn King Kali Yuga]]" to add , who outright shuts down every other card on the field when Summoned and can also either destroy every [[Spell]]/[[Trap]] on the field or [[Set]] a "Dark Contract" card from your GY. However, "Kali Yuga" is not alone, as "[[D/D/D Deviser King Deus Machinex]]" is another terrific Xyz Monster to utilize that can outright absorb other monsters before it by [[attach]]ing them as [[Xyz Material]]s, not unlike "[[Cyber Dragon Infinity]]". It is also incredibly easy to Summon as it can use ''any'' "[[D/D/D]]" monster as [[material]], which can include the Main Deck to opponent's monsters with the handuse of "[[D/D/D Headhunt]]".

Additionally, One of the Deck has access best "D/D/D" monsters to many cards that can recycle resources Summon from the Graveyard, face-up from the [[the Extra Deck]], and the [[Pendulum Zone]]s, such as is "[[D/D Lilith/D Abyss King Gilgamesh]]", since it requires only 2 "D/D/D Oblivion " monsters, and in return immediately sets up the player's Pendulum Scale with monsters straight from the Deck, granting them all the benefits of "Zero King Rage" and "Abyss Ragnarok" and "straight away. Upon being [[destroy]]ed by the opponent, "Gilgamesh" will also replace himself with a fellow "D/D/D Human Resources]]"monster from the Extra Deck or GY, of which requires the player to carefully utilize resources from many different regions there are plenty of the fieldgood choices.

The "D/D/D" archetype is a sub-archetype ===Weaknesses===Because this Deck focuses on [[swarm]]ing to push the "D/D", and consist of more powerful monsters, including Fusiongame, cards that can disable or counter swarming or [[Synchro Monster|Synchrosearch]]ing, like "[[Xyz Monsters|XyzFossil Dyna Pachycephalo]], and " or "[[Pendulum MonsterThunder King Rai-Oh]]", can greatly hinder this Deck. Additionally, the archetype's. The synergy with the "D/D[[Dark Contract]]" monsters are used archetype provides a weakness to facilitate [[Spell]]/[[Trap]] removal, as well as a dependence on cards that mitigate the Summons of damage from the "D/D/DDark Contract" cards. The archetype is also lacking in dealing with monsters. Examples are outside of battle, with their only forms of effect removal being "[[D/D NighthowlDark Contract with the Witch]]" and or the monster effect of "[[D/D Berfomet/D Deviser King Deus Machinex]]", which make . Cards that also negatively affect certain [[Synchro Summon|SynchroAttribute]] and s, such as "[[Xyz SummonShadow-Imprisoning Mirror]]ing much easier by Summoning the required Material from the Graveyard and manipulating the Materials' Levels", respectivelyare also potentially deadly.

Similar to the field effect of "Thomas": "D/D Berfomet" can change the Level of a "D/D" monster to anywhere from 1-8, but restricts Special Summoning to Monsters from this archetype. The only [[Xyz Monster]]s for this effect are "Duo-Dawn", "D/D/D Wave King Caesar" or [[D/D/D Marksman King Tell]]. With the release of ''[[Structure Deck: Pendulum Domination]]'', "[[D/D Savant Copernicus]]" and "[[D/D Savant Newton]]" provide more consistent Pendulum Scales than "D/D Savant Kepler" and "[[D/D Savant Galilei]]". "Copernicus" has the bonus of dumping "D/D" cards from the Deck to start combos, whereas Newton can discard itself to add a "Dark Contract" card or a different "D/D" monster from the Graveyard. "[[D/D Orthros]]" is a reusable Tuner monster, by virtue of also being a Pendulum Monster, to make Synchro Summons easier to execute. "[[Dark Contract with the Yamimakai]]" can set the Pendulum Scales from the Graveyard or Extra Deck to start Pendulum Summoning. ===Manga===In the manga, "D/D" has a vastly different play-style. Unlike its anime counterpart, it doesn't focus on Fusion/Synchro/Xyz Smmoning or negating effect damage from the "Dark Contract" Recommended cards. Instead, it focuses on reducing the DEF of the opponent's monsters to 0 (reflecting [[Reiji Akaba (manga)|Reiji]]'s obsession with the number zero in the manga) and dealing piercing damage. However, it does make use of Pendulum Summoning. ==Weaknesses==Because this Deck focuses on swarming to push the game, cards that can disable or counter swarming or searching, like "[[Fossil Dyna Pachycephalo]]" or "[[Thunder King Rai-Oh]]", can greatly hinder this Deck. Additionally, the archetype's synergy with the "Dark Contract" archetype provides a weakness to Spell/Trap removal, as well as a dependence on cards that mitigate the damage from the "Dark Contract" cards.  ==Recommended cards==
