Dragon Ruler " Dragon Ruler " ( Japanese : " Seiryū " ) is a series of Dragon - Type Effect Monster s consisting of two smaller groups : Level 7 monsters whose ATK and DEF always have a sum of 4600 , and lower - Level monsters that act as miniatures of the Level 7 monsters . Playing style . The " Adult " " Dragon Rulers " all share three characteristics : Each " Baby " " Dragon Ruler " can Special Summon one Level 7 " Dragon Ruler " of the same Attribute from the Deck , though that monster cannot attack that turn . The series proved to be far too synergistic and powerful . The " OCG " and " TCG " Forbidden and Limited Lists experimented throughout the months following their release , first with the " Baby " Dragon Rulers Forbidden in the September 2013 lists , then the " Adult " Dragon Rulers Limited , and finally the series was eradicated in April 2015 with the " Adult " Dragon Rulers Forbidden , and the now - useless " Babies " Unlimited . Generally , each " Dragon Ruler " can be used as support to decks of their corresponding Attribute , such as : You can banish one of the " Adult Rulers " to summon another one , use the banished card ' s effect to add a Dragon - type Tuner from your Deck to your hand , Normal Summon it , and use them to Synchro Summon a powerful Monster . Alternatively , you can use two " Adult Rulers " to Xyz Summon " " to steal your opponent ' s chosen monster and attack directly with it , or even use " Mecha Phantom Beast Dracossack " to summon two " Mecha Phantom Beast Tokens " and Tribute one of them to destroy your opponent ' s monster . Weaknesses and counter - strategies . Cards that can shut down or slow this deck are cards that stops the opponent from banishing , discarding , or prevent Special Summoning . Having both a " Mind Drain " and " Soul Drain " on the field will completely shut down this Deck , but " A Wingbeat of Giant Dragon " , " Twin Twisters " , " Stamping Destruction " , " Cosmic Cyclone " , and " Royal Decree " can eliminate this threat . While " Mind Drain " is active on the field you ' ll be prevented from using " Dragon Ruler " effects that banish / discard from the hand . While " Soul Drain " is active on the field you ' ll be prevented from using " Dragon Ruler " effects that banish / add from activating from the Graveyard and Banished Zone . Cards that prevent players from Special Summoning , such as " Archlord Kristya " , " Evilswarm Ophion " , " Fossil Dyna Pachycephalo " , " Crimson Blader " and also " Barrier Statue of the Abyss and " Barrier Statue of the Heavens " can prove problematic as this Deck relies heavily on Level 7 and higher monsters . " Dragon Capture Jar " and " Buster Blader , the Dragon Destroyer Swordsman " can prevent your Dragons from attacking or activating their effects no matter they be in your hand , Graveyard , or banish . " Summon Limit " can prevents Xyz Summoning Rank 7 monsters indirectly , while also hampering your Normal Summon and other Special Summons . Also , " Imperial Iron Wall " , " Chaos Hunter " , or " Kycoo the Ghost Destroyer " prevents banishment attempts , effectively blocking any Dragon Ruler ' s Special Summon as well . " Banisher of the Radiance " , " Banisher of the Light " , " Dimensional Fissure " and " Macro Cosmos " can banish the Dragon Rulers , rendering them un - Summonable or at least , forcing cards like " Dragoncarnation " to retrieve them back . " Goblin of Greed " also prevents the player from using the discard - based effects of all the " Rulers " themselves .
