Atlantean " Atlantean " , known as " Sea Emperor " ( " Kaiō " ) in Japan , is an archetype of WATER Sea Serpent - Type monsters . They were first introduced in " Phantom Darkness " , with " Atlantean Pikeman " . They later gained more members in " Return of the Duelist " , " Realm of the Sea Emperor Structure Deck " , which also introduced their first support card , " Atlantean Marksman " , and " Lord of the Tachyon Galaxy " which introduced " Legendary Atlantean Tridon " . Story . In an attempt to conquer both sea and land of their region , the " Atlanteans " , led by their Emperor , " Poseidra " , began an attack on the tropical island of the " Fire King s " . However , they resisted the attacks , dragging the war to a standstill . As a way to win their battle , the " Atlanteans " sought the " Mermail s " , who had lost their home . Using the power of their sealed treasure , the Golden Ring that could control the weather , " Poseidra " once again began an attack against the " Fire Kings " , but this time , using the military power of the " Mermails " . Playing Style . The focus of this archetype is to swarm the field with Level 3 or lower WATER monsters with the effects of " Atlantean Marksman " , " Deep Sea Diva " and " Atlantean Heavy Infantry " to later Tribute them for the summon of their ace monster , " Poseidra , the Atlantean Dragon " , or to Synchro Summon with " Deep Sea Diva " and " Genex Controller " , preferably the " Ice Barrier " Synchro Monsters . Also , the effects of " Marksman " , " Heavy Infantry " and " Atlantean Dragoons " trigger when they are sent to the Graveyard as a cost for a WATER monster ' s effect , so cards like " Abyss Soldier " and " Gungnir , Dragon of the Ice Barrier " would be good additions to the Deck . " Atlantean " effects also activate if they are detached from an Xyz Monster ( the effect only requires the monster to be sent to the Graveyard , like " Dandylion " ) , so a great addition to this Deck are WATER Xyz Monsters , like " " . Here is a list of WATER Xyz Monsters that can Trigger the effects of the " Atlantean " ( note that all current " Atlantean " that share this effect are Level 2 , 3 or 4 . However , you can use cards like " Lemuria , the Forgotten City " for Xyz Summoning some of these higher Rank monsters ) : The Spell Card of this archetype , " Call of the Atlanteans " , allows you to Summon 3 Level 3 or lower Sea Serpent - Type monsters from your Graveyard , but you can ' t Special Summon the turn it is activated , and there must be at least 3 acceptable monsters in your Graveyard . Since most of the effects of " Atlantean " activate when they are sent to the Graveyard , the latter shouldn ' t be so hard , but cards like " Skreech " can help you dump cards . " Call of the Atlanteans " is a Quick - Play Spell Card , you can activate it during your opponent ' s End Phase , so you can Special Summon normally in your turn , as long as it was set before . " Atlantean " Decks run cards that clean the field before attacking . " Genex Undine " can destroy any card your opponent controls by sending either " Marksman " or " Heavy Infantry " from you Deck to the Graveyard , while adding a " Genex Controller " ( a Level 3 Tuner ) to your hand . " Abyss Soldier " and " Abyss Warrior " can trigger the effect of the " Atlantean " monsters while returning a monster to the hand and a card in the Graveyard to the top or bottom of the Deck , respectively . The newest addition to the archetype , " Neptabyss , the Atlantean Prince " , greatly increases the Deck ' s consistency . Like " Undine " , " Neptabyss " can trigger the effects of " Atlantean " monsters from the Deck , and it can search any " Atlantean " card , including " Call of the Atlanteans " . Although its effect can only be used once per turn , you can reuse it on your following turns by using the " Call of the Atlanteans " you searched . Additionally , it ' s second effect lets you Special Summon an " Atlantean " monster from your Graveyard , except another " Neptabyss " , which allows you to recycle your monsters without needing cards like " Salvage " and " Mermail Abyssturge " . This archetype also goes hand - in - hand with the " Mermail " archetype since most of the " Mermails " effects involve discarding a water monster as a cost which will in turn activate the " Atlantean ' s " effects . By using " Mermail Abysspike , " " Mermail Abyssturge " and / or " Mermail Abyssmegalo " with the " Atlanteans " you will be able to activate their useful effects and the " Atlanteans " effects together . One of the great support cards for this Deck , " Deep Sea Diva " , can Special Summon any low - Level " Atlantean " monster from your Deck . If you choose to summon " Marksman " , every time you inflict battle damage to your opponent , you can Special Summon another " Atlantean " monster from your Deck , like " Atlantean Attack Squad " for a beatstick , while also having monsters for a Rank 3 Xyz monsters , or Synchro material for Level 4 Synchro Monsters or above . Also you can Special Summon " Heavy Infantry " with her effect which will allow you to normal summon an extra sea - serpent type monster like " Marksman " , " Dragoons " or best of all another " Deep Sea Diva . " There are many choices for Synchro Monsters . You can go for " Ally of Justice Catastor " ( " Diva " + " Marksman " or " Assaultman " ) , " Gungnir " ( " Diva " + " Armed Soldier " + " Marksman " ) and any other of your choice . The " Ice Barrier " Dragons discard cards to activate their effects , which clean the field by themselves . " Brionac , Dragon of the Ice Barrier " can return any card on the field to the hand any number of times in your turn , so you can use its effect to return one " Atlantean " monster in your field , then discard it to return another one to the hand , and since it was discarded , its effect activates . Use " Atlantean " monsters in combination with " Koa ' ki Meiru Ice " . " Ice " will be a 1900 beater that allows you to destroy , multiple times during the same turn , a Special Summoned monster and a Set or face - up card depending on what " Atlantean " you pay for the cost with . To keep your " Ice " alive , you will need to have a " Iron Core of Koa ' ki Meiru " or a Continuous Spell Card in your hand . A recommended Continuous Spell Card could be " D . D . Trench " or " Water Hazard " . A card that you can use with " Atlanteans " is " Raging Eria " due to her cost of tributing a WATER monster to activate her effect . You can tribute cards like " Marksman " or " Heavy Infantry " to Special Summon a WATER monster from your hand while destroying a card your opponent controls . You can also tribute " Dragoons " to Special Summon a WATER monster while adding a Sea Serpent monster from your Deck to your hand . " Raging Eria " can also help with summoning high level monsters easier like " Poseidra " or even " White Night Dragon " , a powerful WATER monster . There is a loop you can do if you get " Dewloren , Tiger King of the Ice Barrier " and " Gungnir " on the field with a " Diva " in your hand . Summon the Diva , Special Summon " Heavy Infantry " or " Marksman " , bounce " Diva " and the " Atlantean " , discard the " Atlantean " with " Gungnir " , repeat next turn . This leaves you with " Dewloren " at 3000 ATK , and your opponent ' s field wiped by " Gungnir " and the discarded " Atlantean " . Without the diva you can use " Surface " or " Call of the Atlanteans " , Special Summon the monster ( s ) that fit your need , then bounce the monster ( s ) with " Dewloren " , and discard it with " Gungnir " . Through use of " A Legendary Ocean " , it is possible to use the " Dragoons " effect to attack directly with it and any level 4 Sea Serpents . Through this , you can also allow " Marksman " to do battle damage unhindered by the opposing monsters , getting out " Attack Squad " and dealing another substantial blow to the opponents life points . Also , because of the lowered levels , all non - tribute " Atlantean " monsters are protected by " Aegis of the Ocean Dragon Lord " , allowing this to take place on multiple turns without worry of cards like " Mirror Force " . Another great card for the Deck is " Cold Enchanter " , which can be used for a massive damage card . Also since it ' s effect can be activated multiple times per turn , it works amazingly with " Snowdust Giant " an amazingly powerful Xyz monster for the Deck . You simply detach one material from " Snowdust Giant " and reveal the " Atlanteans " you are going to discard with " Cold Enchanter " then distribute the counters among the two monsters , you then discard the very " Atlanteans " you revealed for the effect of " Snowdust Giant " through the effect of " Cold Enchanter " to increase her attack largely and decrease your opponents attack massively . Official Decks . Atlantean OTK . This OTK focuses on using " Mermail Abyssmegalo ' s " double attack ability to deal massive damage . What you need : How it Works : Atlantean OTK ( Simpler Version ) . What you will need : How to Pull it off : Atlantean OTK ( " Neptabyss , the Atlantean Prince " Variant ) . What you will need : OR OR AND How to Pull it off : This OTK can be pulled off with somewhat more difficulty when " Dragoons " is in your hand , by using the effects of " Mermail Abyssteus " , or " Mermail Abysspike " to discard him , adding " Abyssmegalo " to your hand . You still need only 1 WATER monster in your hand to do this , because " Abyssteus " and " Abysspike " both can add 1 " Mermail " monster from your Deck to your hand . You will , however , need some monster to Tribute to activate " Abyssmegalo " ' s effect , such as " Abyssteus " or " Abysspike " , as well as a monster to remain on field to inflict the final 1600 or more points of damage . You can use " Neptabyss " to Tribute for " Abyssmegalo " if you used " Abyssteus " to get rid of " Dragoons " , as " Neptabyss " can still Special Summon " Dragoons " from the Graveyard , and then you will have " Abyssmegalo " , who attacks twice and has 3200 ATK , " Abyssteus " , who has 1700 ATK , and " Dragoons " , who has 1800 ATK .
