Butterfly Dagger - Elma 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 . " There are a number of variations of the OTK , but generally all revolves around these two cards : The other half of the cards depend on the victory condition a player is going for . There are three main OTK ' s which can all be incorporated into a single deck : " Exodia " ( special win ) , " Fire Princess " or " Chaos Emperor Dragon - Envoy of the End " ( burn ) , and " Magical Marionette " ( beatdown ) : Exodia . Get " Gearfried the Iron Knight " and " Royal Magical Library " face - up on the field , then equip " Gearfried " with " Butterfly Dagger - Elma " . " Royal Magical Library " gains a counter and " Butterfly Dagger - Elma " is sent to the Graveyard due to " Gearfried ' s " effect , which is immediately returned to your hand . You repeat this process while drawing a card every 3 times thanks to " Royal Magical Library ' s " effect . Theoretically , you can draw your entire Deck , along with " Exodia " , and win the duel . You can use this combo as many time as you like during your turn . If you don ' t want to take risks about your opponent destroying one monster before the other is summoned , you should add " Ultimate Offering " or " Double Summon " to your Deck . This combo can be combined with the " Chaos Emperor Dragon " OTK . Fire Princess . This OTK requires four cards to give you a lot of Life Points , while " Fire Princess " inflicts damage . First activate " Spell Absorption " . Then Summon " Gearfried the Iron Knight " . Finally , activate " Butterfly Dagger - Elma " and gain 500 Life Points . Equip it to " Gearfried " . His ability will destroy " Butterfly Dagger - Elma " and send it to the Graveyard . Next , " Butterfly Dagger - Elma ' s " effect activates , returning it to your hand from your Graveyard . Repeat the last 3 steps to receive lots of Life Points for the " Fire Princess " to destroy your opponent with . If you repeat this process 16 times in succession you will win . Also works with " Morale Boost " . Magical Marionette . This OTK is not as reliable as other well known combinations , as it leaves room for the opponent to use such cards as " Sakuretsu Armor " or " Magic Cylinder " in a counter - attack . The cards needed are as follows : The object is to get " Gearfried the Iron Knight " and " Magical Marionette " on the field successfully . Once this is done , continually equip " Gearfried the Iron Knight " with the " Butterfly Dagger - Elma " . While you are doing this , " Magical Marionette " is gaining an infinite amount of Spell Counter s due to his effect . Since his ATK increases by 200 points for each counter , the limit of his attack effectively becomes infinite as well . As an added bonus , if you remove two Spell Counter s from " Magical Marionette " , you may destroy 1 monster on the field . This allows you to clear as many monsters as you need from your opponent ' s side of the field , and still have well over enough ATK to finish your opponent in one , brutal move . Adding in " Royal Decree " can stop your opponent from using Trap Cards against you . You can use " Mega Ton Magical Cannon " to clear your opponent ' s field . This strategy can be fused with the " Fire Princess " strategy . Simochi Anti - Heal ( Burn ) . Using " Butterfly Dagger - Elma " continuously , you may recover the opponent ' s LPs with " The Magician " , but with " Simochi " , your opponent loses LPs . This combo may be sped up with " Upstart Goblin " . Chaos Emperor Dragon - Envoy of the End . Similar to the Exodia OTK , you need to have " Gearfried the Iron Knight " and " Royal Magical Library " , f ace - up on the field . Equip " Gearfried " with " Butterfly Dagger - Elma " and place 1 Spell Counter on " Royal Magical Library " . " Gearfried " then destroys " Butterfly Dagger - Elma " and sends it to the Graveyard , then " Butterfly Dagger - Elma " returns to your hand . Repeat this two more times . Now " Royal Magical Library " has 3 Spell Counters on it . Remove them to draw a card . Repeat this process multiple times and draw many cards from your Deck . From this point there are 2 alternatives : If you already drew " Graceful Charity " , draw cards until your Deck has 3 cards left . Play " Graceful Charity " , draw 3 cards , then discard 1 LIGHT monster and 1 DARK monster . Banish the 2 monsters from your Graveyard and Special Summon " Chaos Emperor Dragon - Envoy of the End " . Activate its effect and " burn " your opponent . If you didn ' t draw " Graceful Charity " and you drew " Darkness Approaches " , draw all the cards in your Deck . Activate " Darkness Approaches " , and discard 1 LIGHT monster and 1 DARK monster and flip a monster face - down . If your opponent has no monsters on their field , flip " Royal Magical Library " face - down . Banish the 2 monsters from your Graveyard and Special Summon " Chaos Emperor Dragon " . Activate its effect and " burn " your opponent . This combo can deal a huge amount of damage . If you go first and you have the following in your opening hand : " Gearfried the Iron Knight " or " Royal Magical Library " , " Butterfly Dagger - Elma " or " Hidden Armory " ( to get Butterfly Dagger - Elma to your hand ) , " Foolish Burial " ( to send either " Gearfried " or " Royal Magical Library " to the Graveyard depending of which of the 2 you drew ) and " Monster Reborn " ( to Summon the monster you sent to the Graveyard ) , you can deal 12 , 000 damage ( 35 cards to the hand and on the field + 5 cards in your opponent ' s hand ) to your opponent if you drew " Butterfly Dagger - Elma " or 11 , 400 if you drew " Hidden Armory " ( or 11 , 700 if the card you sent to the Graveyard from the top of your Deck was " Butterfly Dagger - Elma " ) . Tempest Magician . This combo focuses around Spell Counter s for " Tempest Magician " . Special Summon " Oracle of the Sun " and use " One for One " to Special Summon Level 1 Tuner Monster or " Double Summon " both " Gearfried the Iron Knight " and the Level 1 Tuner Monster . Tune both the Level 5 and Level 1 monsters to Synchro Summon " Tempest Magician " . Activate " Magical Citadel of Endymion " ( if you don ' t have " Magical Citadel of Endymion " use " Terraforming " to search for " Magical Citadel of Endymion " ) to gain Spell Counter s from the " Gearfried " / " Dagger " combo until you have 16 counters on it , then remove them for " Tempest Magician ' s " effect to get rid of your opponent ' s Life Points .
