World Lock

A World Lock down deck is a lockdown deck revolving around Arcana Force XXI - THE WORLD. All you need to do for this combo is have these 3 cards where needed:


 * Arcana Force XXI - THE WORLD on the field with it's "heads" effect applied
 * 2 Samsara Lotus in the Graveyard or 1 Treeborn Frog and 1 Samsara Lotus.

During your End Phase, if XXI is on the field and he has his Heads effect applied, you resurrect the 2 Lotus' 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 backrow a turn earlier), and then ending, once again resurrecting the Lotus needed for XXI's effect and tributing them for another turn skip. This is repeated until your opponent has lost, and can't be stopped once it begins. 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, ect.

Another alternative for the lock uses 2 D.D. Scout Planes and a Strike Ninja. Here's how it works:
 * Both Scout Planes are sent to the graveyard to activate the effect of THE WORLD.
 * Strike Ninja is summoned, and removes himself from play by removing both Scout Planes in the Graveyard from play.
 * At the End Phase, both Scout Planes and Strike Ninja return to the field. The Scout Planes are sent to the Graveyard for the effect of THE WORLD.

Cards recommended for this deck:
 * Arcana Force XXI - THE WORLD
 * Foolish Burial
 * Samsara Lotus
 * Kaiser Sea Horse
 * Armageddon Knight
 * Mystic Tomato
 * Gellenduo (stalls for time, and can be a double-tribute for XXI.)
 * Premature Burial
 * Celestial Transformation
 * Monster Reborn
 * Reversal of Fate(ensures of it's "Heads" effect.)
 * Hand Destruction
 * Card Destruction
 * Giant Trunade
 * The Transmigration Prophecy
 * Heavy Storm or Malevolent Catastrophe (for destroying your own spell or trap cards)

In a deck like this, you're better off avoiding cards such as Second Coin Toss or Light Boundary, unless you are intending to run Heavy Storm, Giant Trunade and Mystical Space Typhoon with the exception of using the alternate strategy.
