Cyber - Stein OTK " This deck is considered a Classic Deck , this page is used to tell the history of a deck rather than how it is played now . This can happen either from mechanics of the game changing , changes from the " TCG " or " OCG " Forbidden / Limited List , or the deck has slowly lost it ' s ability to be played over time due to years of no support or neglect . " This OTK is now no longer possible in Advanced Format , since " Cyber - Stein " was listed as Forbidden in Advanced Format and Limited for Traditional Format as of December 21st , 2006 , in a surprise move by Konami / Upper Deck Entertainment ( UDE ) . This combo can possibly be performed in the " OCG " , as Konami have moved this card ' s status from Forbidden to Limited during February 2014 in based on February 2014 Lists . Classic OTK . Key Cards . In order for this OTK to work you must let your opponent go first since the player who started the duel cannot attack . You ' ll need either a clear field , or the ability to make your monster strong enough with either " Megamorph " and " Fairy Meteor Crush " or " Big Bang Shot " so that no matter what monster your opponent plays , you ' ll still deal enough Battle Damage to win . ( If you have " Cyber End Dragon " you won ' t need the Fairy Meteor Crush which has the same effect ) First , summon " Cyber - Stein " and activate its effect , pay ing 5000 Life Points to summon the Fusion Monster . Then , activate " Megamorph " and equip it to the Fusion Monster . Since your Life Points will most likely be lower than your opponent ' s after the 5000 Life Points cost of " Cyber - Stein " , " Megamorph " will double the Fusion Monster ' s ATK points to at least 8000 , exactly enough to wipe out your opponent . Alternate Method . Key Cards . On your turn , set " Ring of Destruction " . You ' ll need a clear field for the next part , so " Nobleman of Crossout " and " Nobleman of Extermination " may come in handy . Assuming a clear field , summon " Cyber - Stein " , activate his effect , and summon " Cyber Twin Dragon " from your Fusion Deck ( YOU 3000 / OPP 8000 ) . Attack your opponent directly twice with " Cyber Twin Dragon " ( YOU 3000 / OPP 2400 ) , then activate " Ring of Destruction " , selecting " Cyber Twin Dragon " ( YOU 200 / OPP 0 ) . You can also use " Shooting Star Bow - Ceal " to attack directly so you don ' t interfere with your opponents flip effects that might mess you up with your combo . Another way you can OTK with Ring of Destruction is to use any of the monsters with 4000 + ATK mentioned above . Special Summon that monster using Cyber - Stein , then activate Ring of destruction . Then Chain Barrel Behind the Door to avoid taking damage and do at least 8000 damage to your and take no damage from Ring of Destruction . Alternate Method 5 ( more Fusion options ) . On your turn , Normal Summon Cyber - Stein . Activate it ' s effect and summon the chosen fusion monster . Activate Megamorph , Twin Swords of Flashing Light - Tryce , and Shooting Star Bow - Ceal and equip them to it . Attack directly , twice , for win . ( Stats will be XXX0 , x2 , - 1500 ; so , only a base Atk of 2750 is actually needed , allowing this to be done with many more fusion monsters ) . Costless Fusion OTK . Key Cards . " Activate " " DNA Surgery " and " Brain Research Lab " and " Normal Summon " " Cyber - Stein " as fast as possible . You can also search " Brain Research Lab " easily with " Terraforming " . Change all the " Type " of the " Monster " to " Psychic " and use the effect of " Cyber - Stein " to " Special Summon " any of the " Fusion Monster " . As " Cyber - Stein " is now " Psychic " - type , you just place 1 Psychic Counter on " Brain Research Lab " instead of paying 5000 Life Points to " Special Summon " any of the " Fusion Monster " . Repeat this step to summon any of your " Fusion Monster " as many as possible . The release of " Xyz Monster " also boost this combo . " Xyz Summon " by using any " Fusion Monster " on the field and " Direct attack your opponent with all the " Monster Card " on the field . The examples of " Xyz Monster " that are having a difficult summon condition like " Superdreadnought Rail Cannon Gustav Max " or " Superdimensional Robot Galaxy Destroyer " can be summon easily with " Cyber End Dragon " or " Destiny End Dragoon " .
