World Lock = How it works = A World Lock down deck is a lockdown deck revolving around " Arcana Force XXI - The World " . All you need to complete this Lockdown is a constant source of monsters that " Arcana Force XXI " can send to your Graveyard to activate its effect . It is important to know that Token Monsters cannot activate " The World ' s " effect , since they cannot be used for costs that require monsters to be sent outside the field . Frog Method ( Traditional Format ) . This is perhaps one of , if not the easiest and efficient way to perform the lockdown . For the lockdown , you need : It ' s kind of self - explanatory . You ' re simply reviving " Treeborn " and " Ronintoadin " each turn as food for " The World " . The reason this is an easier method than others is because it ' s easy to fill your Graveyard with Frog s for the lock with cards like like " Substitoad " ( Traditional Format ) and " Swap Frog " . If you get " The World " out with its " tails " effect applied , you can easily use " Swap Frog " ' s effect to return it to your hand , or " Reversal of Fate " to switch to its " heads " effect . To obtain the right cards , " Moray of Greed " is recommended . Samsara Lotus Method . One popular way to complete this lock is by using the following cards : During your End Phase , if " XXI " is on the field and he has his " Heads " effect applied , resurrect the 2 " Samsara " s from your Graveyard ( using their effects ) and then Tribute them for " XXI " ' s effect , skipping your opponent ' s next turn . On your next turn , attack your opponent ( preferably after clearing your opponent ' s back row a turn earlier ) , and then resurrect the " Samsara " s needed for " XXI " ' s effect . This is repeated until your opponent has lost , and is nearly unstoppable . It is much safer to do this after their Spells and Traps are empty , preventing you from falling to a " Sakuretsu Armor " or " Mirror Force " . It is also useful to control a " Prime Material Dragon " or " Des Wombat " to prevent damage from " Samsara Lotus " . If for any reason you find a Spell or Trap card on your side of the field , a good backup is " Black Ptera " . Be warned that cards like " Vanity ' s Fiend " and " Divine Wrath " can break this combo . Traps . The Traps are optional because " Samsara Lotus " and " Treeborn Frog " cannot be Special Summoned if there are Spell or Trap cards on your side of the field . D . D . Scout Plane / Strike Ninja Method . Another alternative for the lock uses the following cards : During your Main Phase , activate the effect of " Strike Ninja " to Banish 2 " D . D . Scout Plane s " . During your End Phase , because of their effect , your " D . D . Scout Plane s " are Special Summoned to the field and " Strike Ninja " returns as well . " Arcana Force XXI - The World " sends these two " D . D . Scout Plane s " to your Graveyard to trigger its effect and this loop repeats until the duel ends . " Bazoo the Soul - Eater " would be a better choice because it states that you can Banish monsters in order to gain 300 ATK until the end of your opponent ' s next turn but they won ' t have another turn so " Bazoo " will continue to gain attack . This method is superior , although less popular than the one using " Samsara Lotus " , because it allows the user to use Spell and Trap cards such as " Valhalla , Hall of the Fallen " , " Light Barrier " , and other helpful Spell cards that remain on the field , as well as " Allure of Darkness " , which isn ' t usable in the Samsara Strategy due to the fact of how inconvenient it is to have " Samsara Lotus " removed from play . Also , because " Strike Ninja " is searchable with cards like " Reinforcement of the Army " , the combo is simple and more practical to complete . An important thing to know about this strategy is that if the World cannot send a monster to the Graveyard , then it cannot skip the opponent ' s turn . Therefore , " Dimensional Fissure " and " Macro Cosmos " cannot work in here , and also , this combo finds it difficult to win against Macro Cosmos Decks . Plaguespreader Zombie / Quillbolt Hedgehog method . This method uses the following cards : It works in a similar fashion to the " Quillbolt Loop " . Once " The World " is summoned , return a card to the top of your deck to Special Summon a " Plaguespreader Zombie " which you have already sent to the Graveyard . Now that a Tuner monster is on the field , you can also revive " Quillbolt Hedgehog " . Tribute these two for " The World ' s " effect to skip your opponent ' s next turn . Your hand will never run out of cards even if you only have one card in it when you start ( you must have at least 1 ) , since you will continually draw the card you put on top of your deck , then return it to the top of your deck . The downside of this deck is that since it is reliant on " Imperial Iron Wall " it can be difficult to clear your opponent ' s backrow without ruining the lockdown . " Makyura the Destructor " and " Temple of the Kings " can help alleviate this in Traditional Format , but in Advanced format you must simply rely on your opponent not having enough powerful Spells or Traps to ruin the lockdown . It ' s also a good idea to use " Seven Tools of the Bandit " and " Trap Jammer " . Note that , because of " Imperial Iron Wall " , this method cannot overlap with the other two outlined above . Destiny Hero Departed Lockdown Method . Have two copies of " Destiny Hero - Departed " in your Graveyard as well and " Imperial Iron Wall " and " Remove Brainwashing " Face - up on the field together with " Arcana Force XXI - The World " and its heads effect applied . When your Standby Phase arrives , the two " Departeds " in your Graveyard will be Special Summoned to your opponent ' s side of the field . " Remove Brainwashing " will return them to your side of the field so that you can tribute them during your End Phase for " Arcana Force XXI - The World " . Continue doing this until your opponent has 0 life points . Drill Warrior / Level Eater Method . Monster Cards . Quickdraw Synchron < br > Level Eater < br > Arcana Force XXI - The World < br > Drill Warrior < br > Spell Cards . Valhalla , Hall of the Fallen < br > Second Coin Toss < br > Light Barrier < br > Trap Cards . Reversal of Fate < br > Dark Bribe < br > Seven Tools of the Bandit < br > Use Valhalla to Special Summon The World , then discard a Level Eater to Special Summon Quickdraw Synchron . Normal Summon another Level Eater and Synchro Summon Drill Warrior . Reduce Drill Warrior ' s level by 2 to Special Summon the 2 Level Eaters from the graveyard . Now activate Drill Warrior ' s effect and remove it from play . At the End Phase , send the two Level Eaters to the grave to skip your opponent ' s turn . When Drill Warrior returns , it ' s level will be reset to six , allowing you to re - Summon the Level Eaters . Rinse and repeat until you win .
