Machine King ( series ) " Machine King " is a series of monsters who , for the most part , gain ATK when there are other Machine monsters on the field . The lores of some Machine cards mention serving the " Machine King " . However , it is unknown which model of the " Machine King " they serve ( most likely " Machine King " , since it was generally the only card of that name out at the time of their release , but this could generally mean any of them ) . Machine King Deck . A Machine King Deck focuses on the titular cards and swarming the field with Machine monsters . However , this is not limited to your own monsters , you can also swarm your opponent ' s field and then use " DNA Surgery " to change them all into Machines . Strategy . This deck is essentially a Billy Beatdown Deck , as " Machine King " and its counterparts all focus on increasing its own attack through your own field presence . Commonly used with it is " DNA Surgery " , so that your opponent ' s monsters are also changed to machines . Because " Machine King " and " DNA Surgery " can only benefit / affect face - up monsters , " Light of Intervention " will immensely help , as well as to get rid of annoying effects . You should have three copies of DNA Surgery and perhaps one or two " Light of Intervention " to speed this up , as it will allow even " Machine King Prototype " to gain a substantial ATK boost . " United We Stand " is also useful , as well as " Fairy of the Spring " to return " United " . " Big Bang Shot " and " Fairy Meteor Crush " are likewise good choices for this Deck , since your opponent will more than likely play monsters in Defense Position hoping to prevent potential damage . Machine support cards such as " Limiter Removal " work well in this Deck too . Although using " Limiter Removal " is somewhat reckless , doubling the ATK of all your Machine monsters for one turn could be just what you need to win the Duel . However , the real power of this Deck lies in your ability to swarm the field with monsters , including your opponent ' s field if you have " DNA Surgery " , because more monsters means more ATK for " Machine King " . So be sure to include cards that can swarm , such as " Phantom Skyblaster " and " Grinder Golem " , for they each create Tokens to power up your " Machine King " monsters . " Creature Swap " makes a great addition if you decide to use either monster , allowing you to give your weaker Token monster to your opponent while they give you one of their actual monsters . Also , having many Tokens gives you free Tribute for activating " Nightmare Archfiends " . Giving your opponent 3 high ATK monsters might seem like a bad idea at first , but once you use the Trap card " Remove Brainwashing " , all those high ATK monsters will become yours assuming you have unoccupied Monster Zones , if not your opponent will take 800 points of damage for each Token destroyed , which is favorable result anyway . Not to mention that the same works for " Grinder Golem " which will switch to your control as well when " Remove Brainwashing " is on the field giving you a whopping 3000 ATK monster in addition to your " Machine Kings " . Ironically enough , because this Deck uses " DNA Surgery " to change monsters to the Machine Type , Machines of over 500 ATK are not really needed unless they have a substantial or effect , such as " Cyber Dragon " . " Gilasaurus " and " Inferno Reckless Summon " can put more monsters on your opponent ' s field . While this is normally avoided , each monster will grant a " Machine King " an additional ATK boost . However , Token creation cards such as " Scapegoat " can fill your monster zone with Machines to boost " Machine King " when " DNA Surgery " is active . " Ojama Trio " is a good choice , since it fills 3 of your opponent ' s monster card zones with useless monsters that are ideal targets for attacks . " Final Attack Orders " can also be used to inflict more damage , while giving you more ATK , especially if " Ojama Trio " was played , because it forces all monsters on the field into Attack Position , creating more opportunity for heavy battle damage . Since all monsters on the field will be Machines , you can use " Acid Rain " , or , more preferably , " System Down " if you need to clear the field of monsters . " Chimeratech Fortress Dragon " can be deadly in this Deck . Because you can use your opponent ' s Machines as Fusion Materials for that card , when " DNA Surgery " is on the field you can clear your opponent ' s field for a direct attack . " Proto - Cyber Dragon " or " Cyber Dragon Zwei " will allow you to use this effect more often . Either way , 1 " Cyber Dragon " is a great help . Perhaps the most over - looked card for this Deck , ironically , is " Perfect Machine King " . With no real easy way to Summon it , and no inherent effects that protect it from your opponents cards , it seems like a waste of Deck space . But with 2700 ATK plus an additional 500 points for each Machine on the field , squeezing it into your Deck might not be a bad idea . If you decide to use " Perfect Machine King " , then cards such as " Cyber Phoenix " are necessary , as " Cyber Phoenix " protects all your face - up Machines from Spells and Traps that target , so that cards such as " Brain Control " , " Sakuretsu Armor " and " Dimensional Prison " become useless against your Machines . Advantages and Disadvantages . This Deck is a good counter to Type - specific Decks , such as Plant , and to Swarm Decks , as they will simply fuel the effect of " Machine King " . " Uria , Lord of Searing Flames " is also somewhat compatible with this Deck , as there are many Continuous Trap Cards that are crucial to this Deck . " Light of Intervention " will also cripple most Rock Decks . However , this Deck is weak against mass Trap removal , which is quite common . " Perfect Machine King " , in particular , is a Level 8 monster , making it somewhat hard to Summon considering it has no uniquely easy way of Summoning . It is also vulnerable to most card - destruction effects , as it ' s one of the few newer two - Tributes with no innate effect negation and destruction . " Machine King " , as well , is particularly weak even with its effect , as it ' s ATK is lackluster to begin with and its boost is not that substantial .
