Infernity " Infernity " ( インフェルニティ " Inferuniti " ) , is an archetype of DARK monsters used by Kalin Kessler in " Yu - Gi - Oh ! 5D ' s " . They consist of monsters whose effects activate when a player has no cards in hand . In episodes 33 - 35 in the dub of " Yu - Gi - Oh ! 5D ' s " , the archetype was referred to as " Infernalty " . The first " Infernity " cards were released as promotional cards in " " : " Infernity Archfiend " , " Infernity Dwarf " , and " Infernity Guardian " . " Infernity Destroyer " was released in the " Yu - Gi - Oh ! 5D ' s Stardust Accelerator - World Championship 2009 Game Guide " in Japan . The first " Infernity " card released in a booster pack was " Infernity Beast " in Ancient Prophecy . Two additional " Infernity " cards soon followed with the release of Stardust Overdrive : " Infernity Necromancer " and the first " Infernity " Trap Card " Infernity Force " . With the release of The Shining Darkness , fifteen more cards were added to the " Infernity " archetype . The Shining Darkness also included the " Infernity " Synchro Monster " Infernity Doom Dragon , " " Photon Shockwave " introduced " Infernity Knight " and last , Cosmo Blazer introduced Infernity Archer . The " Infernity " Deck received some major boosts with the advent of Xyz monsters . The first is " Leviair the Sea Dragon " , which can be made with two " Infernity Necromancer " s , two " Tour Guide From the Underworld " s , or a combination of the two . " Hundred Eyes Dragon " or " Infernity Break " can banish " Infernity Mirage " with its effect , and " Leviair the Sea Dragon " can then revive the " Infernity Mirage " for a Synchro Summon and an " Infernity Archfiend " search , as the restriction on its Special Summon only applies to the Graveyard . Another handy Xyz monster is " Lavalval Chain " . Its effect can place " Infernity Archfiend " on top of your deck , which can lead to its Special Summon on the following turn if your hand is empty . While it is on the weaker side in terms of ATK and DEF , if " Lavalval Chain " manages to survive into a second turn , it can use its other effect to set up your Graveyard with whatever " Infernity Archfiend " searched out . " Void Ogre Dragon " and " Beelze of the Diabolic Dragons " are welcome additions to the " Infernity " arsenal of Level 8 Synchro monsters , having great synergy with the deck and able to fend off threats such as " Dark Hole " and most common defensive traps . Lastly , " Infernity " Decks serve as a great engine to easily Summon all of the " Red Dragon Archfiend " , including " Red Nova Dragon " , " Hot Red Dragon Archfiend Abyss " and " Hot Red Dragon Archfiend Bane " , possibly even in one turn . Design . Appearance . " Infernity " monsters ' artwork owes much to stereotypical depictions of the " wild west , " with cards such as " Infernity Archfiend " , " Infernity Necromancer " , and " Infernity Mirage " alluding to the Native Americans , while cards like " Infernity Avenger " , " Infernity Randomizer " , and " Infernity Launcher " ( whose original Japanese name was " Infernity Gun " ) relate to cowboys . More recent " Infernity " monsters like " Infernity Knight , " " Infernity General , " and " Infernity Archer " bear strong medieval overtones . Etymology . " Infernity " is a portmanteau of the words " Infernal / Inferno " and " Infinity " . Play style . The deck relies on an empty hand . Using discard ing effects like " Dark Grepher " and " Summoner Monk " is the fastest way to empty your hand while setting up your Graveyard for cards like " Infernity Launcher " , " Infernity Necromancer " and " Infernity Avenger " . With the release of " The Shining Darkness " , the " Infernity " archetype ' s strategy became Graveyard - centric . Because the most common way of emptying the hand is through discarding effects , the Graveyard should load up very quickly with " Infernities " to Special Summon with the effects of " Infernity Mirage " , " Infernity Necromancer " and " Infernity Launcher " . As a bonus , " Infernity Avenger " can Special Summon itself from the Graveyard in response to the destruction of an " Infernity , " maintaining field advantage while also potentially returning as a level 3 + Tuner . Note , it ' s best to avoid cards like " Full Salvo " , " Fine " , and " Rope of Life " , because although they empty the hand , they typically don ' t generate more than momentary advantage . An " Infernity " player should always plan for the long - term . A well - built " Infernity " Deck can churn out several powerful Synchro Monsters and Xyz Monsters per turn . " Infernity Launcher " can allow for even more Synchro Summons and Xyz Summons via a combination of " Infernity Necromancer " , " Infernity Archfiend " , and / or " Infernity Avenger " . With the release of " Lavalval Chain " , most " Infernity " decks have changed to run only " Infernity Avenger " as their Tuner or no Tuners at all to ensure a low monster count considering " Infernity Beetle " is only useful when running 3 . However , " Mist Wurm " can still easily be made with two Level 4s and an Avenger . " Infernity Mirage " can Tribute itself to Special Summon two more " Infernity " monsters from the Graveyard , for yet another Synchro Monster or an Xyz , if need be . Namely " Leviair the Sea Dragon " Another good Synchro Monster is " Hundred Eyes Dragon " : its ability essentially makes it a fourth copy of any " Infernity " monster , provided it exists in the Graveyard . Normally , you will use its effect to copy either " Infernity Necromancer " or " Infernity Mirage " , which will let you Summon back other Infernity monsters in your Graveyard to gain further advantage . If usng Mirage - make sure the latter was Properly Synchro Summoned so you waste not much time summoning it back . Strengths . The most noticeable strength of an " Infernity " Deck is its easy Synchro Summoning and Xyz Summoning capabilities . The archetype also boasts its own Counter Trap Card in the form of " Infernity Barrier " - a card that can Negate virtually anything - as well as its own Normal Trap Card in " Infernity Break " which takes care of any threats that Infernity Barrier cannot handle . " Infernity " decks create long chains of Synchro and / or Xyz Summons , which concludes with up to three primed " Infernity Barriers " and " Infernity Breaks " backing a field of powerful Synchro and / or Xyz Monsters . This set up is nearly invincible if achieved . Weaknesses . " Infernities " , despite their enormous Synchro Summoning and Xyz Summoning capability , have a number of crucial weaknesses . Post - September 2010 . After the September 2010 Forbidden list ' s restriction on " Infernity Launcher " , the " Infernity " Deck began to lean on its control aspect . " Infernity Avenger " replaced " Infernity Beetle " as the deck ' s primary Tuner . It allows " Infernities " to Summon level 8 Synchro monsters with relative ease , which , without the OTK potential offered by a full play - set of " Infernity Launcher " , is necessary for the deck ' s continued viability . Given that , " Hundred Eyes Dragon " is arguably the most important Synchro monster in the " Infernity " arsenal . As touched upon , it can banish " Infernity Mirage , " copy its effect , and then Special Summon " Infernity Archfiend " and " Infernity Necromancer " . This triggers a search out of " Infernity Archfiend " , usually for " Infernity Barrier " , " Infernity Launcher " , or " Infernity Mirage " . Then , " Infernity Necromancer " Special Summons " Infernity Avenger " , which is used to Synchro Summon for another Level 8 Synchro monster . Note that this monster could be another " Hundred Eyes Dragon " , which would restart this cycle with the addition of a set " Infernity Barrier . " These loops are best finished with " Infernity Doom Dragon " : not only a 3000 ATK beatstick equipped with a Burn and destruction effect , but more importantly , an " Infernity " monster with which to fulfill the activation requirement of " Barrier . " " Stygian Street Patrol " has some synergy with the deck , although it can be a bit slow if drawn as opposed to being sent straight from the Deck to the Graveyard . It acts as a Special Summon outlet for " Infernity Archfiend " if it ' s the last card in hand , and as a means of barraging an opponent with Synchro monsters by Special Summoning an " Infernity Mirage " searched by " Infernity Archfiend " after a Normal Summon . If included , a balance between " Armageddon Knight " and " Dark Grepher " as opposed to just " Dark Grepher " is preferred , as " Infernity " Decks tend to have a lower monster - to - Spells / Traps ratio than most Decks , rendering " Dark Grepher ' s " discard unwieldy . With the release of " Lavalval Chain " , the " Infernity " Synchro deck now has much more consistency . It allows for more consistent Synchro Summoning and faster Graveyard set - up , without having to use slow and inconsistent cards such as " Infernity Inferno " , " Wave - Motion Inferno " , " Dark Eruption " , " Into the Void " , and " Phantom Hand " by instead using cards such as " Summoner Monk " , " Instant Fusion " and " Transmodify " . See Post Duel Terminal 7 for more information . Post - Duel Terminal 7 . After the release of " Lavalval Chain " in Duel Terminal 7 , some players began focusing the " Infernity " Deck solely on Xyz Summoning rather than Synchro Summoning . As a result , the deck has greater resistance to the dreaded " Evilswarm Ophion " . The Xyz version of the Deck now focuses entirely on Rank 3 and Rank 4 Xyz Monsters . The only " Infernity " Monsters that are needed in the Deck are " Infernity Archfiend " and " Infernity Necromancer " . " Archfiend " is everything to this deck ; it searches the key cards and facilitates the negation ability of " Infernity Barrier " . " Lavalval Chain " can place him on top of the Deck every turn , netting you a free " Infernity " card every draw phase . This Deck attempts to Xyz Summon " Lavalval Chain " as soon as possible through the use of cards like " Stygian Street Patrol " , " Instant Fusion " and " Summoner Monk " . By using " Chain " , you can draw into " Infernity Archfiend " every turn , allowing him to search out the Deck ' s key trap cards , " Infernity Break " and " Infernity Barrier " . These traps negate or destroy your opponent ' s cards , giving the " Infernity " Deck more of a Stun feel than ever before . " " is a very useful Xyz monster in this deck . If you have the option to Xyz summon a second Xyz monster after " Lavalval Chain " , " Master Key Beetle " can send another " Infernity Archfiend " to the graveyard while also allowing you to protect your " Infernity Barrier " s from " Mystical Space Typhoon " , a card often used to pick off your " Infernity Barrier " s . " Seven Tools of the Bandit " is a good trap card for protecting your " Infernity Barrier " s and monsters from cards like " Mirror Force " and " Compulsory Evacuation Device " . " Archfiend Heiress " and " Archfiend Palabyrinth " work incredibly well in this deck . " Dark Grepher " , " Armageddon Knight " , " Lavalval Chain " , and " Foolish Burial " can all activate the effect of " Archfiend Heiress " , which allows you to add 1 " Archfiend Palabyrinth " to your hand from your deck . Using " Archfiend Palabyrinth " , you can banish either a used - up " Infernity Necromancer " or another " Infernity Archfiend " to special summon " Infernity Archfiend " from your deck . Usually , banishing " Infernity Necromancer " doesn ' t put you at a disadvantage if you have already used its effect to special summon an " Infernity Archfiend " from your graveyard , because special summoning another " Infernity Archfiend " will allow you to add " Infernity Barrier " to your hand , setting you up for an OTK in the second turn with the + 500 ATK boost " Archfiend Palabyrinth " offers . Another way some players run this deck is by still using 1 " Infernity Avenger " as a Tuner , and focusing primarily on Synchro Summoning but using the " Lavalval Chain " combos and other combos from the Xyz deck to help you Synchro Summon and gain advantage faster . Also , you may possibly use 1 " Infernity Mirage " for the Hundred Eyes combos . This version of the deck can easily Synchro Summon " Hundred Eyes Dragon " , " Void Ogre Dragon " , or " Infernity Doom Dragon " ( and on occasion two of the forementioned in one turn depending on how well you drew ) first turn whilst also having Infernity Barriers searched the same turn , and not slowing down the deck at all because " Lavalval Chain " , " Summoner Monk " , " Armageddon Knight " , " Instant Fusion " , " Transmodify " and " Dark Grepher " make it extremely easy to get your Graveyard set up with everything you need for your Level 8 Synchros . You simply use the same combos as in the Xyz version , but send an " Infernity Avenger " to your Graveyard at some point then use " Infernity Necromancer " to resurrect him after having an " Infernity Archfiend " out on your field as well . Getting these three out on the field at once is extremely easy , you can use " Summoner Monk " to summon whatever monster you need at the time , then " Instant Fusion " for another " Lavalval Chain " if need be to send another card you need to your Graveyard , and " Infernity Launcher " to resurrect them all . You can send " Stygian Street Patrol " s to your Graveyard as well , then Special Summon the cards you need for the combo using his effect . " Transmodify " works very well in making your first turn Level 8 Synchros . You can use it on an " Infernity Necromancer " after already having used the " Infernity Necromancer " to Special Summon from your Graveyard " Infernity Avenger " or " Infernity Archfiend " . This will let you Special Summon another " Infernity Archfiend " for an extra " Infernity Archfiend " search . Then with " Infernity Launcher " discard the " Infernity Avenger " you added to your hand and Tribute the Launcher for a Level 8 Synchro , after Xyz Summoning into a " Lavalval Chain " to send more monsters to your Graveyard you may need for the combo using the " Infernity Archfiend " you just summoned . Another great way is using " One for One " to both discard a monster you need in your Graveyard whom you had already searched using " Infernity Archfiend " , then summon " Infernity Mirage " to Special Summon from your Graveyard Archfiend , Necromancer , and Avenger . There are many combos to make the first turn Level 8 Synchros and you do it using almost the same ways you make multiple Xyz first turn . This version of the deck gives the player extra negation power using " Void Ogre Dragon " , good plays for future turns using " Hundred Eyes Dragon " ( especially when combined with " Lavalval Chain " ) , and easy monster destroying with burn damage without the risks attacking brings using " Infernity Doom Dragon " . All three of these monsters also have an extremely powerful 3000 ATK , whereas the Xyz variant ' s strongest monsters are only 2500 ATK . " Hundred Eyes Dragon " is arguably the most important Synchro monster in this build . By Synchro Summoning " Hundred Eyes Dragon " while also having a " Lavalval Chain " out ( which you normally will ) , you can use " Lavalval Chain " to send whichever monster you want from your Deck to your Graveyard , then use " Hundred Eyes Dragon " to copy that monster ' s effects . With an " Infernity Necromancer " in your Graveyard , you can use " Hundred Eyes Dragon " to banish it and copy its effects then gain the ability to Special Summon an " Infernity Archfiend " from your Graveyard . Then , with " Infernity Archfiend " ' s search you can grab another " Infernity Necromancer " , and Normal Summon it , then activate its effect to Special Summon " Infernity Avenger " , then Synchro Summon into another Level 8 Synchro . Also , you can search more " Infernity Barrier " s via this combo too . You can also use " Hundred Eyes Dragon " ' s effect to copy " Infernity Mirage " instead . By tributing himself to Special Summon " Infernity Archfiend " and " Infernity Necromancer " , you can gain another " Infernity Barrier " and a different Level 8 Synchro . Because " Hundred Eyes Dragon is not solely limited to copying only " Infernity " monsters ' effects , you can also copy " Summoner Monk " and gain the ability to summon another Level 4 monster from your Deck by discarding a Spell . Also , you can copy " Dark Grepher " to send even more monsters to your Graveyard and give you even more plays depending on what else you have out on your field . Keep in mind also , that since " Hundred Eyes Dragon " copies the name of the monster you banish as well as their effects , if you copy " Infernity Necromancer " or " Infernity Mirage " you now also meet the requirements to activate " Infernity Barrier " . " Void Ogre Dragon " is an extremely powerful monster in this deck . Not only does it have 3000 ATK , but it can negate a Spell / Trap once per turn during either player ' s turn , unlike " Infernity Barrier " which just negates one card . Also , you can push for wins faster often due to the fact that you can negate a Spell / Trap on your turn right after Synchro Summoning " Void Ogre Dragon " , whereas you must set " Infernity Barrier " before you can activate it . Because you can have " Void Ogre Dragon " on the field alongside other " Infernity " monsters with " Infernity Barrier " s set , your negation power is virtually unstoppable . " Infernity Doom Dragon " will allow you to destroy monsters without having to attack the turn you added your " Infernity Barrier " s to your hand . Since you can ' t activate " Infernity Barrier " the turn you set it , this is extremely useful for destroying your opponent ' s monsters if they have backrow you may be worried about . More importantly , " Infernity Doom Dragon " can fulfill the requirements to activate " Infernity Barrier " as a 3000 ATK monster , giving your opponent a hard time finding a way around the " Infernity Barrier " s come their turn . " Infernity Avenger " also meets the requirements to activate " Infernity Barrier " , giving you more use out of your " Infernity Barrier " s . Additionally , Avenger can be resurrected if a monster you control is destroyed by battle , and gain the Level of that monster . This is very useful for both avoiding attacks from your opponent and for more Synchro Summoning . You can even have your own monsters destroy themselves by attacking an opponent ' s monster , and then gain another Level 8 Synchro in your second " Main Phase " . Normally , the only Xyz Monster you usually will need to use in this build is " Lavalval Chain " . Besides that , you will usually Synchro Summon even though you only run 1 Tuner . However , you can still easily Xyz Summon if you need to , giving you no hassle against " Evilswarm Ophion " .
