Metalfoes " Metalfoes " , known as " Metalphosis " ( メタルフォーゼ " Metarufōze " ) , in the " OCG " is an archetype of FIRE Psychic monsters that debuted in " The Dark Illusion " . " Master Peace , the True Dracoslayer " and " True King Agnimazud , the Vanisher " appear to have a relation to this archetype , as seen in the cards " Metamorformation " and " Metalfoes Combination " respectively . Design . Appearance . The monsters of this archetype are based on the anime " " and " " , the latter of which has been adapted into " " . The Fusion Monsters resemble the Pendulum Monsters ' vehicles transformed into power suits , as depicted in " Metalfoes Fusion " and seen with " Goldriver " and " Orichalc " , the latter of which resembles the MOSPEADA unit in its battle form . Other " Metalfoes " members are based off other popular media such as " Akira " and " " . Etymology . " Metalphosis " is a portmanteau of " Metal " and " Metamorphosis " . While the Pendulum Monsters of this archetype are named after real life metals / alloy , the mythical and legendary metals / alloy are used for Fusion Monsters . Playing style . The Main Deck " Metalfoes " monsters are comprised of Normal Pendulum Monster s , except for the Effect Pendulum Monster " Raremetalfoes Bismugear " , that all have the Pendulum Effect to destroy one of the player ' s own cards and Set a " Metalfoes " Spell or Trap Card from the Deck simultaneously . Their playstyle is similar to the " Igknight " archetype , which is also FIRE Pendulum - based deck with tendencies of destroying each other to search one another . Because they can destroy any face - up card to have their effects running , they are largely viable to be used with several cards or archetypes that benefit from destruction such as " Yang Zing " in order to generate multiple advantage in rapid succession . Aside from Pendulum Summoning , this archetype can Fusion Summon with " Metalfoes Fusion " , which can easily return itself to the Deck for a free draw ; it can then can be searched out again with the Pendulum " Metalfoes " monsters to repeat the process . " Metalfoes Combination " can be used with " Painful Decision " to gain more field advantage from Fusion Summons while also recovers those spent monsters . Furthermore , most " Metalfoes " Fusion Monsters require completely generic materials - further emphasizing their splashability and capacity for mixing with other Decks with little problem . Mixing in other Pendulum archetypes can allow for powerful field presence , using Pendulum Monsters as materials from the field , and Pendulum Summoning those materials back from the Extra Deck later . The effect of " Metalfoes Orichalc " gives all " Metalfoes " monsters double piercing damage , which allows them to benefit from cards that force your opponent ' s monsters into Defense Position , such as " Book of Moon , " " Book of Eclipse , " " Swords of Concealing Light , " and " Quaking Mirror Force " . Alternatively the player can also focus on the Field Spell " Metamorformation " which renders all non - effect " Metalfoes " monsters unaffected by the opponent ' s cards effects while giving them a 300 ATK / DEF boost , making otherwise simple monsters into far more formidable threats . The Deck ' s Link Monster , " Heavymetalfoes Electrumite " , acts as resource management , being able to recycle Pendulum Monsters from the Extra Deck back to the hand for use as Scales or Summoning , as well as draw power should any Pendulum Scale s leave the field , allowing players to maintain the number of resources in the hand . Also , since its second effect destroys face - up cards on the field , it can be used to trigger the " Metalfoes " Trap Cards .
