Harpie " Harpie " ( ハーピィ " Hāpyi " ) is an archetype composed of WIND Dragon and Winged Beast monsters . Mai Valentine uses this archetype in the anime and manga . " Sky Scout " , originally known as " Harpie ' s Brother " , is not a Harpie card because it does not have 「 ハーピィ 」 in its Japanese name . It was renamed to clarify this . When " Harpies " were released ( some of the first monsters released that would later become an official archetype ) , they didn ' t have much support . From " Rise of Destiny " onward , however , " Harpies " became more balanced and powerful with occasional support cards released . " " has aided this archetype with cards such as " Hysteric Party " and " Harpie ' s Pet Baby Dragon " , while also featuring a lot of other Harpie - related cards in it . Afterwards , " Harpie Queen " was released in " Force of the Breaker " , providing ways to search " Harpie ' s Hunting Ground " . With the release of " Lord of the Tachyon Galaxy " , Harpies get some tremendous boost , while also solidifies the deck ' s focus of maintaining advantage and Xyz Summoning . " Harpie Channeler " is essentially the main card in all Harpie - based decks , as she can Special Summon another Harpie monster from the Deck while also assists Xyz Summoning of Rank 4 or 7 , while " Hysteric Sign " helps searching either " Elegant Egotist " or any Harpie cards you may need , depending on how you use it . The Xyz Monster in this archetype , " Harpie ' s Pet Phantasmal Dragon " can protect your other Harpie monsters from attacks or targeting effects , along with direct - attacking ability as well . " " also provides more support for this archetype ( while also reprinting important Harpie - related cards as well ) . " Harpie Dancer " ' s effect can be utilized for reaping more benefits from " Harpie ' s Hunting Ground " , or providing more swarming capabilities when coupled with " Divine Wind of Mist Valley " . They also have their ultimate Spell Card , " Harpie Lady Phoenix Formation " , which can decimate your opponent ' s field of monsters , but disallows you to Special Summoning monsters from your Deck , Graveyard and skipping your Battle Phase , making it a double - edged sword with hefty drawbacks . Maximum of 3 Rule . " Harpie Lady 1 " , " Harpie Lady 2 " , " Harpie Lady 3 " and " Cyber Harpie Lady " have the name condition " " ( This card ' s name is always treated as " Harpie Lady " . ) " " . Since they all have their name treated as " Harpie Lady " everywhere , including while in the player ' s Deck , a player can only have a total of 3 of any of these cards and / or the Normal Monster " Harpie Lady " in their Main Deck and their Side Deck combined ( for example , 1 " Harpie Lady " , 1 " Cyber Harpie Lady " , and 1 " Harpie Lady 2 " ) . " Harpie Queen " , " Channeler " , " Dancer " and " Harpist " each have an effect that treats their own name as " Harpie Lady " while they are on the field or in the Graveyard . However , since they are treated as their original name in the Deck , it is possible to have up to 3 of each in addition to 3 cards whose name is treated as " Harpie Lady " in the Deck . Media appearances . In the anime , the " Harpies " are the signature cards of Mai Valentine . She often begins with one " Harpie " card and uses support cards to accessorize and multiply it . Joey Wheeler also used some " Harpie " cards as a reminder of his promise to save Mai from her Penalty Game . A " Harpie Lady " also appears as a Duel Monster Spirit in " Yu - Gi - Oh ! GX " . She battles Jesse Anderson and his " Crystal Beast Sapphire Pegasus " . That same " Harpie Lady " later uses the effect of " Elegant Egotist " to multiply into 3 , but they were defeated by " Sapphire Pegasus " and " Topaz Tiger " . Alexis Rhodes , Jasmine and Mindy dress up as the " Harpie Lady Sisters " in Yu - Gi - Oh ! GX . In " Yu - Gi - Oh ! 3D Bonds Beyond Time " , at the site of Maximillion Pegasus ' s tournament , one of the spectators cosplays as a " Harpie Lady " . In " Yu - Gi - Oh ! The Falsebound Kingdom " , the Harpie Ladies are given names , each based on those of three Harpie sisters from Greek mythology : In the " Yu - Gi - Oh ! Tag Force " series , Jasmine plays a " Harpie " Deck . Censorship . Most " Harpies " in the international release of the game , including all language prints except Japanese , and in the anime have been edited to appear to wear bodysuits while in the Japanese versions they wear much more revealing clothing . " Cyber Harpie Lady " and " Harpie Lady Sisters " have had the spikes extruding from their armor removed due to the suggestiveness . However , some earlier printings of a few of the " Harpie " cards outside of Japan ( specifically the original " Harpie Lady " and " Harpie Girl " ) were printed without being censored . Playing style . " Harpies " combine the ability to be rapidly summoned , to destroy the opponent ' s Spell and Trap Cards , increase each others attack points , enhancing their individual abilities , and to protect each other . They do not have the ability to destroy Spell and Trap cards innately , but their Field Spell Card , " Harpies ' Hunting Ground " allows them to destroy one Spell or Trap Card when a " Harpie Lady " card is Summoned in any way . They can be Summoned from the Graveyard in large numbers through the effect of " Hysteric Party " . Their support cards , " Harpie ' s Pet Baby Dragon " and " Harpie ' s Pet Dragon " , rapidly gains power ( " Harpie ' s Pet Dragon " ) or utility ( " Harpie ' s Pet Baby Dragon " ) depending on how many Harpie Lady cards you control . Properly played , " Harpies " can overwhelm the opponent in moments with high attack power and powerful effects , but they are not strong individually , so they are vulnerable to opponents who can overpower them , or destroy all of them at once . Post - " Lord of the Tachyon Galaxy " , the deck now centered around Xyz Summoning , utilizing cards like " Harpie Channeler " , " Elegant Egotist " , Summoner Monk " , and " Hysteric Party " to Summon multiple Harpies as fast as possible , and perform multiple Xyz Summons ( mainly Rank 4 and Rank 7 ) . Some popular Xyz Monsters found in most Harpie decks including , but not limited to , " Ice Beast Zerofyne " , " Lightning Chidori " , " " , " Castel , the Skyblaster Musketeer " and occasionally " " and " Mecha Phantom Beast Dracossack " . Some players can also include cards like " Blackwing - Zephyros the Elite " and " Tempest , Dragon Ruler of Storms " to promote their swarming power for more Xyz Summons . To keep their onslaught running , they also utilize " Hysteric Sign " for searching more Harpie cards and maintain card advantages in their favor , while using " Harpie ' s Hunting Ground " and " Icarus Attack " as control measures to destroy any obstacles your opponent may utilize . Due to the change in format , it ' s recommend to run Link Monsters such as " Greatfly " to not only retain their Xyz Swarming power but to also increase their Atk . Weaknesses . Despite the many powerful combos that " Harpies " are capable of , there are still weaknesses within this archetype that can be capitalized on . For instance , most " Harpie " monsters , except " Cyber Harpie Lady " , " Harpie Queen " , " Harpie ' s Pet Dragon " and " Harpie ' s Pet Phantasmal Dragon " are generally low in original ATK , making them unsuitable in battle against most high - ATK monsters . Since this archetype have emphasis on rapid Special Summoning , anti - Special Summoning cards like " Vanity ' s Emptiness " and " Fossil Dyna Pachycephalo " can be hazardous against this Deck . " El Shaddoll Winda " can also pose problems as well ( albeit " Hysteric Party " can somewhat bypass this ) . Most Harpie - based decks relies on either " Summoner Monk " and / or " Harpie Channeler " to Summon more monsters from the Deck , and without those cards , this deck cannot survive for long , nor accumulating speed for offense , which means effect negations such as " Effect Veiler " or " Breakthrough Skill " , or disruption cards like " Book of Moon " and " Solemn Warning " is very effective against them during early game stage . Since they mostly focused on Xyz Summons , " Flying " C " " can shut down the Deck ' s aggressive stance , and " Thunder King Rai - Oh " can blocks the effects of " Hysteric Sign " , slowing them down .
