Zoodiac " Zoodiac " , known as " Twelve Beasts " ( " Jūnishishi " ) in the " OCG " , is an archetype of Level / Rank 4 EARTH Beast - Warrior monsters that debuted in " Raging Tempest " . " Master Peace , the True Dracoslayer " and " True King Lithosagym , the Disaster " appear to have a relation to this archetype in Duel Terminal Lore , as seen in " Zodiac Sign " and " Zoodiac Combo " , respectively . Design . Appearance . The " Zoodiac " monsters are based on the , with each monster being a slightly anthropomorphized version of their respective animal . Each monster also wears an oversized gauntlet on either their left or right forearm , with which they wield their own respective weapon . Etymology . The Japanese name , " Jūnishishi " , is a play on the terms " " Jūnishi " " ( 十二支 ) , which refers to the twelve signs of the Chinese zodiac , and " " Shishi " " ( 獣 ) , meaning " beast " . The English name , " Zoodiac " , is a portmanteau of the words " zoo " and " zodiac " . Playing style . The archetype ' s Main Deck monsters grants additional effect for any Beast - Warrior Xyz Monster they ' re attached to , ranging from protection against targeting effects , piercing battle damage , banishing opposing monster they battled , or even Summoning more monsters from the Deck . The Xyz Monsters of the archetype , meanwhile , all possess variable ( ? ) ATK / DEF , stemming from the total sum of the ATK / DEF of the " Zoodiac " monsters attached to them . Furthermore , each Xyz Monster can be Xyz Summoned once every turn by using 1 " Zoodiac " monster as Material ( as long their names are different ) . Their Material requirements are generic , which means they can be used in other decks as well . The biggest strength of this archetype is their capability of starting their sequences of play with just one card ( any of their monster ) . With the collective strength from " Ratpier " , " Broadbull " , " Chakanine " , and " Drident " , in addition of having access to cards like " Zoodiac Barrage " , " Fire Formation - Tenki " , and " M - X - Saber Invoker " , gives them unrivaled consistency and card advantages overall , with almost no investment . Because of this , the deck doesn ' t require many of their Main Deck components , allowing them to incorporate several powerful cards that either increase their redundancy ( such as " Shuffle Reborn " or " Soul Charge " ) , protect their field presences ( such as " My Body as a Shield " ) , or even hindering their opponents ( such as the Hand trap s , " Solemn Strike " or " Dimensional Barrier " ) without affecting much of their consistency . By incorporating " Missus Radiant " , they can also mitigate the restriction imposed by the new Master Rule 4 by providing them with power boost , recovery , and two Monster Zones to Summon their Extra Deck monsters . Because of their compact size , they can be included in several other decks ( mainly just " Ratpier " and " Whiptail " in Main Deck , while at least " Broadbull " and " Drident " in Extra Deck ) . With the recent announcement of September 2017 Lists in TCG ( and July 2017 Lists in OCG ) , in which " Zoodiac Broadbull " and " Zoodiac Drident " being Forbidden and " Zoodiac Ratpier " being Limited ( in addition to " Zoodiac Barrage " being also Forbidden in OCG ) , the deck has lost much of their functionality ( albeit their " one - card - Xyz Summon " strength still remains ) . In addition , " Daigusto Emeral " being Forbidden in TCG also greatly weakens their recovery aspect , forcing them to rely exclusively on " Zoodiac Combo " for that purpose , which is also made less reliable due to the Limitation of " Ratpier " . Weaknesses . Despite its unparalleled consistency , redundancy , and speed , it ' s not without its weakness . Their over - reliance on " Ratpier " makes it the prime target of any counter - attempt cards their opponents may utilize , such as " Chain Disappearance " . " Dimensional Barrier " is one of their worst enemy ( and one of the only ones they cannot play around ) , since its effect essentially leaves them without any moves during the turn it resolves . " Ghost Reaper & Winter Cherries " is also deadly for this deck , especially for eliminating " Zoodiac Broadbull " ( which cuts off their main source of card advantage ) , or " Zoodiac Drident " ( leaves them unable to interrupt opponent ' s moves ) . In addition , cards like " Dark Hole " and " Interrupted Kaiju Slumber " can easily dismantle the deck ' s field presence ( if no protection cards like " My Body as a Shield " are present ) .
