Vylon " Vylon " ( ヴァイロン " Vairon " ) is an archetype that debuted in " Duel Terminal - Vylon Descends ! ! " and focuses around the use of Equip Card s . Design . Appearance . The monsters appear as angelic , vaguely humanoid machines , have LIGHT as their Attribute , and have either Fairy , Machine , or ( in one case ) Thunder as their Type . Their team symbol is a golden - orange orb , often with gold metal trim . Etymology . The names of various cards from the archetype are based on mathematical concepts and constants . This may or may not be a reference to a famous church official who once told a mathematician that " there are angels in your angles . " The Tuner monster s of this group are shaped and named after three - dimensional geometric figures ( " Prism " , " Cube " , " Sphere " , " Tetra [ hedron ] " , " Stella [ Octangula ] " ) , and the Union Monster s are based on four - dimensional figures ( " Tesseract " , " Pentachloro [ pentachoron ] " ) . The five Vylon Synchro Monsters are each named after the phonetic pronunciation of a Greek letter . Some have bodies resembling their letter ( " Vylon Epsilon " , " Vylon Sigma " , " Vylon Omega " ) , while others have something on their bodies that resembles it ( " Vylon Alpha " , " Vylon Delta " ) , and they all have Roman Numerals corresponding to their order in the Greek Alphabet written vertically on their chests . The Xyz Monster of this group , " Vylon Disigma " , is named after an archaic Greek letter . Story . In the story of the Duel Terminals , the Vylon are holy machine weapons created by the Constellar in The Ancient Era to oversee the seal they had placed upon the Steelswarm , and were designed to be impervious to the corruption of the Lswarm . As ages passed and the Constellar returned to the stars , the Vylon merely observed the confrontations that took place on the Surface World below . Even through the wars against the Worm s and the Fabled s and the resulting devastation caused by the Ice Barrier Dragons , they stayed silent . Within the second generation of the Duel Terminals , the Vylon choose to appear during a conflict that breaks out between the Laval and Gem - Knight tribes , descending from the heavens amidst the fighting and forcing a temporary ceasefire between the warring clans . " Gishki Noellia " , a former member of the Ice Barrier possessed by the madness of the Lswarm , revives the Steelswarm by launching an assault on the Gusto tribe in their homeland of the Mist Valley Marshlands , trying to gain control of a certain shrine . Feeding off the chaos of the fighting , the Steelswarm break free of their containment and ravage the Surface World , seeking revenge on those that had sealed them away long ago . The Vylon relay this turn of events to the Constellar before turning their attention to the battles ahead . The fated collision , that which they had been created for so long ago , awaited them . To combat this powerful threat and common enemy , the four tribes of Gem - Knight , Laval , Gusto and Gishki create an alliance under the umbrella of the Vylon forces . In their time of need , the Vylon send each of the tribes new power via " Vylon Element " . War rages against the onslaught of the Steelswarm and many are lost , including " Vylon Alpha " . The final battle reaches its appex when " Steelswarm Hercules " rises to end it himself . Suddenly " Vylon Omega " arrives from the Vylon Element gateway to turn the tides ! Omega descends upon the field of battle to cast judgment , vaporizing all the lesser Steelswarm that draw near . The war is decided when the two leaders clash , and in the end both lie defeated . Peace after their victory doesn ' t last as the other tribes soon return to fighting over their petty conflicts . The Vylon cannot understand such disunion , and the defeat of the Steelswarm is shown to have had an effect on them : during the final battle , when " Vylon Tetra " was used in a ritual by Noellia to merge into Tetrogre , the evil of the Lswarm possessing Noellia touched the hive - mind of the Vylon . The resulting madness quickly spread through the Vylon ranks , warping them in a way that the Lswarm never could physically . The Vylon resolve to exterminate the other tribes to end their on - going feuds for good and create the perfect utopia . " Vylon Stigma " , " Vylon Tesseract " and " Vylon Pentachloro " join to create the seeker of absolute unity , " Vylon Disigma " . The four tribes are forced to unite once again , sharing their powers to combat this friend - turned - foe . Disigma absorbs members of the other tribes , gaining the power to defeat each one in turn and heavily damaging them . Disigma decides the fate of " Evigishki Merrowgeist " , " Evigishki Gustkraken " , " Lavalval Ignis " , " Lavalval Dragun " , " Daigusto Phoenix " , and " Daigusto Falcos " in his rampage ( minus " Kamui , Hope of Gusto " , who Falcos aided in escaping ) . Only " Gem - Knight Pearl " , created from the strength of the Gem - Knights and the Gishki , proves immune to Disigma ' s absorption ability and has the power to end the twisted angel . With the Vylon crushed , yet another threat is overcome . The true enemy is only just stirring , however , and now the Vylon are not there to oppose it . . . Playing Style . All Vylon Equip Spell Card s can only be equipped to a Vylon Monster and have a secondary effect that allows the player to search for another Vylon Spell Card when they are sent from the field to the graveyard while face up . This is perhaps their greatest asset , as it allows Vylon decks to keep their card advantage from their Spells as long as there are other Vylon Spells in the deck . In " Duel Terminal - Judgment of Omega ! ! " , four Vylon Tuner monsters ( levels 1 through 4 ) were introduced that have the ability to be Treated as Equip Card s when sent from the Monster Card Zone to the Graveyard ( even when used for a Synchro Summon ) at the cost of 500 Life Points , each providing different effects when they are equipped . In " Duel Terminal - Xyz Startup ! ! " , the Vylons obtained two Union Monster s that can be equipped to another Vylon to grant effects when the equipped monster destroys another monster in battle , as well as one of the first Duel Terminal - exclusive Xyz Monster s , " Vylon Disigma " . The Vylon strategy revolves around the use of Equip Card s , their effects often only working when they have at least one equipped . Their Equip Spell Cards can search out other Vylon Spells from the deck when they are sent to the Graveyard from the field , and most of their Tuner and Union monsters ( except " Vylon Cube " ) can become Equip Cards . Their Equip Spells activate even when the monsters they are equipped to are destroyed or used as Synchro Material , letting their users gather the right tools for the situation at hand at any time , though they should always be aware of the number of Spell and Trap Card Zones they have left to work with . One should try to keep at least 1 Spell or Trap Card Zone open so that they can respond should the duel ' s situation suddenly change . Vylon Sigma OTK focuses on Synchro Summoning " Vylon Sigma " , then maxing out its ATK with multiple " Mage Power " and attacking twice with " Twin Swords of Flashing Light - Tryce " for massive battle damage as soon as possible . Vylon Epsilon Control focuses on Synchro Summoning " Vylon Epsilon " quickly and equipping it with " Vylon Segment " to make it and Segment untargetable by most cards , then using Epsilon ' s destruction effect and high ATK to control the field and attack until game . Vylon Element Swarming focuses on utilizing " Vylon Element " to swarm the field with Vylon Tuners ( which can only be used for the Synchro Summon of Vylon Synchro Monster s ) . " Rod of Silence - Kay ' est " can quickly destroy Vylon Equip Cards to activate Element ' s effect . Since the Equip Spells replace themselves with other Vylon Spells ( including Element ) , this can be done over and over in a loop to summon as many Vylon Tuners to the field as there are Vylon Equip Spells in the deck . This variant is capable of Synchro Summoning the mighty " Vylon Omega " , as well as a field ' s worth of Rank 3 or 4 Xyz Monsters ( depending on the Tuners available in the deck ) . Weaknesses . Due to their emphasis on Equip Spell Cards , most Vylon decks are forced to run a low Trap Card count to stay consistent . This makes it hard to respond to the opponent ' s cards , requiring the use of " Vylon Segment " or " Vylon Filament " and high ATK monsters to keep the opponent ' s plays at bay . Since Vylons don ' t have much power to Special Summon themselves , cards that can negate summons like " Solemn Warning " are easy answers to the Vylon Synchro Monsters , and cards like " Macro Cosmos " which Banish your cards will prevent the Equip Spells and Tuners from activating their effects in the Graveyard . " Rivalry of Warlords " can be effective against the Vylon since the archetype is made up of three different Monster Type s even without counting other monsters common to the deck . " Royal Decree " is an excellent choice for disabling your opponent ' s Trap Cards while not affecting you at all , since this deck hardly utilizes any Traps . " Naturia Beast " , " Legendary Six Samurai - Shi En " or any Spell Negation can be problematic against Vylons due to their dependence on Spell Cards . In such a situation , rely on the power of Monster Cards like " Cyber Dragon " , " Photon Thrasher " or " Summoner Monk " and the ability of the Vylon Tuners to become Equip cards from the Graveyard to overwhelm the opponent until you can use Spells again . However , " Dark Highlander " is " the " perfect mis - match against " Vylon " s due to most of said archetype ' s Decks revolving around Synchro Summoning and Equip Spell Cards . " Forbidden Lance " can be very dangerous to Vylon monsters ( especially " Vylon Sigma " ) due to it making all cards equipped to one monster lose their effects upon that monster , in addition to reducing their ATK . " Enemy Controller " can switch the Vylons into their ( usually ) more vulnerable Defense Position , where boosts to ATK won ' t help them , or could even steal your monster away for the turn if your opponent has a Tribute for it . " Book of Moon " can be perhaps even more devastating since it combines the strengths of both of these other cards , though thankfully it is currently Limited in the Advanced Format . " Vylon Segment " can ' t stop any of these cards , and " Vylon Filament " will only help if the opponent is careless enough to wait until your attack to try to use these cards . Element Swarming builds can utilize " Rod of Silence - Kay ' est " to protect their monster against those Spells , though this prevents their own equips from helping them . As with all LIGHT - Attribute archetypes , the Ally of Justice and Koa ' ki Meiru archetypes and " Light - Imprisoning Mirror " , along with other anti - LIGHT support , can paralyze Vylons and their effects . Furthermore , odd Side Deck cards like " Eternal Rest " , " Really Eternal Rest " , " The Emperor ' s Holiday " , " Disarmament " , " Armored Glass " , " Armor Break " and " Collected Power " can extinguish active Equip Spell Card s or even the Vylon monsters themselves . Rely on high ATK and Equip Cards when your monster effects are made useless , and don ' t commit too many monsters to the field , as while the Vylon equips are easily replaced , their monsters aren ' t . Sigma OTK users must always be prepared for backrow , since just one " Dimensional Prison " can dispatch Sigma easily . Moreover , if the OTK attempt fails once , it can be difficult to repeat since most of the Equip Spells needed for it would now be in the Graveyard . Use " Vylon Matter " or " Vylon Ohm " to help recover from such a situation . Epsilon Control defends against several targeting cards , but is still vulnerable to targeting Spells like " Book of Moon " and any cards that don ' t target like " Black Rose Dragon " , " Dark Hole " , " Heavy Storm " or " Mirror Force " . " Dark Bribe " is a valid replacement for " Royal Decree " in this case . Element Swarm users rely on the lengthy Special Summon combo granted by " Vylon Element " , which means cards like " Mystical Space Typhoon " can be dangerous obstacles since they can destroy " Vylon Element " and stop the chain of summons . Although " Vylon Omega " can seem virtually invincible thanks to its high - ATK and monster effect negation , it can still be made vulnerable if it loses its Equip Cards to something like " Heavy Storm " . Try to have an answer for these threats or bait them out before you make any big plays .
