Ever since Code of the Duelist launched last year I've wondered ifa 'World Legacy' strategy was possible.


For example: could you play the World Legacy cards together to benefitmultiple themes at once in a hybrid build? What would that take toaccomplish, and would it be any good? That question faded from my mind lastyear, but when fellow TCGplayer writerFranco Ferraraand I discussed Mekk-Knights a month ago the concept appeared to becomeplausible.

A few weeks of testing later and I now have a build I'm mostly happy with,but more importantly it lays the groundwork for a strategy that's gettingbetter with each new release.

The Legacy Of The World
World Chalice debuted in Code of the Duelist with their supportsplit between two themes: World Chalice and World Legacy. The namingconvention had its drawbacks, particularly with Auram the World ChaliceBlademaster's ATK boost effect, but even then there was an assumption thatmore World Legacy cards were on the way. Krawlers in Circuit Breakhad their own set of World Legacy support cards, including theirall-important Field Spell World Legacy in Shadow. That trend continued withMekk-Knights in Extreme Force, and we'll also see more WorldLegacy cards debut alongside the Troymare theme inFlames of Destruction.

There's potentially another three World Legacy-supported themes arrivingafter Flames of Destruction, and one new World Legacy cardsupporting Mekk-Knights has already been revealed forCybernetic Horizon. What's interesting is that there's just twosearch effects so far: World Legacy - "World Chalice" and World Legacy -"World Armor." Between the two, world Legacy - "World Chalice" issearchable by virtue of being a World Chalice monster, and that makes itmuch more interesting than its World Armor counterpart.

So why do I care about searching World Legacy cards in the first place?World Chalice rarely need them and already play World Legacy - "WorldChalice" for its third effect, and Krawlers can reach their most relevantWorld Legacy through Terraforming. Even Mekk-Knights are competitivelyviable without a single World Legacy card. But there's another build ofMekk-Knights that isn't seeing play, and it's primarily due to a lack ofsearch effects. The overt strategy of Mekk-Knights uses the World LegacyContinuous Spells and Traps to negate cards in the same columns as yourmonsters–the problem is that those World Legacy cards are hard to find.

Mekk-Knights currently have four World Legacy support cards including aField Spell: World Legacy Scars, World Legacy Key, World Legacy Whispers,and World Legacy's Secret. It's the effects of Key, Whispers, and Secretthat transform Mekk-Knights into an engine pumping out a steady stream ofreasonably high ATK monsters into a dedicated control strategy. Each cardnegates a specific type card type that activates in the same column as aMekk-Knight you control. With the column-changing monster Mekk-KnightIndigo Eclipse in play, you can freely negate at least one effect, or youcan fill the field and prevent almost any non-Field Spell from resolvingsuccessfully.


Setting up this disruption is easier said than done. You're effectivelybuilding two cards combos primarily with Indigo Eclipse and one or two ofthe World Legacy traps. World Legacy Key has the best on-field effect, butnegating traps has low utility beyond Evenly Matched, TrickstarReincarnation, and a couple of other match-ups. Whispers and Secret willalmost always be relevant in any match-up provided you can find them. Bothon-theme Mekk-Knight search effects are attached to monsters and onlysearch monsters. That's fine for the engine you'll see in InvokedMekk-Knights, but pure builds are left trying to shoehorn in draw effectsto reach those World Legacy cards.

The competitive solution here is to forgo World Legacy support, add anInvoked engine, and play the Invoked Mekk-Knight strategy that already havea proven record of success. World Legacy's Secret can still be played whengoing first to Special Summon a fallen Invoked Mechaba, so you'll get toexercise a small portion of the column-based negation the theme wasdesigned for. That said, building the deck with a World Legacy searchengine in place is incredibly fun, and there are some unexpected synergiesbetween World Chalice, World Legacy, and Mekk-Knights that makes a hybridbuild worth exploring.

Two Enemies Fight As One
The World Chalice fight against both Krawlers and Mekk-Knights in the WorldLegacy Lore, but we'll be using them together to construct boards full ofinterruption and negation. There's one ideal win condition here: load thefield with enough Mekk-Knights backed by World Legacy spells and traps tostop your opponent's cards from resolving. To do that we need to achievetwo specific goals:

1. Fulfill Summoning conditions for Mekk-Knight monsters by filling columnswith cards in appropriate zones

2. Search or draw into World Legacy spells and traps using World Chalice

The first step is much easier to achieve when you're playing second. Youropponent might have already created a perfect zone for you to Summon yourmonster to with no effort required on your part. You can simply SpecialSummon your Mekk-Knight Purple Nightfall or Mekk-Knight Blue Sky and startsearching, but what if you end up playing first? How do you create openingsif your opponent has carefully positioned their monsters so no column hasmore than one card in it? In a worst-case scenario you might have to createyour own column, but with Grinder Golem Limited that's often not easy.


Filling the Extra Monster Zone's crucial, and that's partially what theWorld Chalice engine seeks to achieve. Any Normal Monster in the deck canbecome a Link Spider or Imduk the World Chalice Dragon, which leaves youwith a single Spell and Trap Zone to fill. Instant Fusion and BrilliantFusion help produce columns where Mekk-Knights can be Summoned, and InstantFusion into Millennium-Eyes Restrict is particularly strong when playingsecond and actively protects you against hand traps thanks to its effect.Keep in mind that you can also Tribute Summon Mekk-Knight Blue Sky toactivate its search effect, so any spell that Summons a monster has utilityeven when you can't form a column.

World Legacy - "World Chalice" helps us achieve that second goal bysearching World Legacy spells and traps on the turn after it was sent tothe graveyard. Although it's painfully slow it's also the most consistentway to reach your negation cards, thanks mostly to Lee the World ChaliceFairy.

You can Normal Summon Lee, search World Chalice, then either Tribute Summonit using an extra Normal Summon offered by Gem-Knight Seraphinite or Imduk,or send it to the graveyard with World Legacy Scars to draw a card. Theformer method is a bit more useful here due to World Chalice's secondeffect, and you can very easily get that extra Summon by drawing into yourcopies of Brilliant Fusion, Transmodify, or Unexpected Dai.

If you can kickstart the World Chalice engine you'll also have a couple ofoptions that let you reach your World Legacy cards even earlier. There aretwo huge draw cards you can fit into your Extra Deck: Ningrisu the WorldChalice Warrior and Saryuja Skull Dread. Summoning either monster will letyou see more cards, and that's incredibly valuable for a strategy that'sreliant on a very specific field configuration. The Agent of Creation -Venus is essentially a one card Saryuja provided you turn two of yourMystical Shine Balls into Link Spider and Imduk.

There's another benefit of reaching Saryuja, or even Firewall Dragon: theycan Special Summon Mekk-Knights from the hand to any zone. It'ssurprisingly useful in situations where you might only have one validcolumn to Summon a Mekk-Knight, but you have two or more in hand. Inparticular it's great going second after resolving a Mekk-Knight Blue Sky.Like Infernoids you can sometimes end up with more monsters than you knowwhat to do with. These Link-4's help you move those monsters from your handto the field so they can start applying pressure to your opponent.

DECKID= 108531There are other cool synergies here with various World Legacy cards. WorldLegacy Key can add a banished World Legacy - "World Chalice" back to yourhand, giving you another card to discard for World Legacy Scars or fodderto pitch for Lee's graveyard effect. World Legacy's Secret can SpecialSummon World Chalice at an ideal moment to activate its on-field effect. Itdoesn't always come in handy, but when it does you can send your opponent'sfreshly-Summoned Extra Deck monster straight to the graveyard.

Transmodify is worth playing within the cfontext of the World Chaliceengine because it can Summon The Agent of Creation - Venus by sending acopy of Lee or Mystical Shine Ball to the graveyard. However, it also workswith the Mekk-Knight engine by trading Mekk-Knight Yellow Star orMekk-Knight Red Moon for Mekk-Knight Purple Nightfall.

Mekk-Knight Blue Sky is also a potential target if you wanted to playMekk-Knight Orange Sunset or Mekk-Knight Green Horizon. Blue Sky itselfcan be Summoned through Transmodify – especially with the upcomingMekk-Knight Avram – but it won't net its effect. PSY-Frame Driver couldalso work as a stepping stone to the Level 8s, although most of the valuewith Transmodify comes from reaching Purple Nightfall anyways.

To be absolutely clear: I don't expect to see a Mekk-Knight/World Chalicebuild topping Regionals anytime soon. This deck has a lot of coolinteractions and the potential to become even better with more World Legacysupport, but in the meantime the power, tempo, and consistency of theInvoked engine.

Still, I've been having a blast playing this deck recently, even withoutSaryuja, and I couldn't wait to share its silly premise andthought-provoking potential. I'm sure we'll be seeing a lot more of WorldLegacy over the next year, and if we do I wouldn't be surprised to findcards like World Legacy Scars and World Legacy Keys in decks withoutMekk-Knights.

Until next time then
