This classic combination was revolutionized with the recent release of the second Machina Structure Deck. It centers on Link Summoning, some Xyz Summoning, and tons of combos.
2 – Cubic Performage

Adapted from CDS: Cubic Performage
Throw a bit of magic into this OTK strategy! This highly aggressive build centers around the Cubic’s innate ability to OTK, but rather consistently with the help of Magicians’ Souls and other burn cards. For this event, the article’s build was updated to include the newest Cubic cards.
3 – The Yosenju Stormforth

Adapted from CDS: The Yosenju Stormforth
This Pendulum-based approach to the Yosenju archetype takes your opponent by a storm, blowing away their monsters with a slow-burning advantage engine with OTK blasts waiting in the wings. For this event, the build was updated to readjust in light of the recent limitation of Card of Demise.
4 – Stormwind Harpie Lady

Adapted from CDS: Elegant Harpie Lady
The next WIND theme of the event features the Harpies, assisted by a bit of Speedroid and Dragunity! Focusing on a mix of Link Summoning, Xyz Summoning, and now Synchro Summoning with the unveiling of the new Harpie Lady Synchro monster, this deck is ready to blow your opponent away.
5 – Tachyon Toolbox

Adapted from CDS: Tachyon Dragon Toolbox
This Dragon-based strategy lives in chaos, wielding the darkness and the light to respond to any situation with a variety of dragonic tools. While there are definitely elements of Xyz Summoning here, this strategy primarily relies on Link Summoning to secure the victory.
6 – Plunder Patroll HERO

Adapted from CDS: Plunder Patroll HERO
This Fiend strategy involves Fusion, Synchro, Xyz, and Link Summoning to pirate away your opponent’s chances of victory. With a strong bent for disrupting the opponent’s plays, who else could contest the high seas?
7 – Infernoble Star Warriors

Adapted from CDS: Noble Warrior’s Strike
This firey take on an equip strategy focuses on utilizing all of the cool cards from the OCG-only structure deck. It offers a mix of aggression, Fusion Summoning, Synchro Summoning, and disruption, resulting in many different win conditions! For this event, the decklist was modified to include more of the new Infernoble cards while still maintaining the original focus.
8 – Virus Resonator

Adapted from CDP: Virus Resonator
Descend into darkness with the Red Dragon Archfiends, supported by a viral team of fork-wielding fiends! This strategy definitely relies on disrupting your opponent through its unique mix of high-octane Synchro monsters and the tributing mechanic!
9 – Forbidden Dark Magician

Adapted from CDS: The Forbidden One
Many Dark Magician builds don’t run too many outside support cards, but this Forbidden approach gives you an incarnate boss monster to center around! Combined with other strong Spellcaster support cards, this control strategy might cast a spell on you. For this event, the Exodia strategy was significantly modernized and shifted to also include Dark Magician support as a core element.
10 – Lords of the Sacred Beasts

Adapted from CDP: Sacred Beasts
With their new Structure Deck, Hamon and Raviel are ready to join the fray as a control deck. Featuring insane life point gains and tons of consistency, this strategy can lock the opponent into making bad choices and ultimately snuff out their LP with a Heaven-Crushing Fist.
11 – Modernized Gravekeeper

Adapted from CDS: Modernized Gravekeeper
What happens when you accelerate the Gravekeeper strategy to high speeds, ensuring the resolution of Royal Tribute on the first turn of the duel? Will that be enough to discard monsters away then seal them into the tombs of Necrovalley? This strategy also embodies the Fusion summoning mechanic through multiple mechanisms!
12 – Metaphys Rokket

Adapted from CDS: Metaphys Rokket
When Dragons and Wyrms unite, a Dracocension can occur! Take to the banished zone and unleash the purified Metaphys archetype upon all opponents! This strategy primarily uses Link Summoning as its core approach, but the main deck offers quite a few boss monsters of its own.
13 – Heart of the Cards Back Jack

Adapted from CDS: Heart of the Cards Mastered!
There are few combinations of cards that grant you an instant win in Yugioh, but this strategy is all about finding the next best thing. Using Back Jack and tons of Normal Traps, this combo deck aims to master swings in tempo to win the duel. This strategy was heavily modernized from its original posting, but I did my best to keep the spirit of the original strategy alive and well!
14 – Ancient Warriors’ Heritage

Adapted from CDP: Ancient Warrior’s Heritage Revisited and CDS: Ancient Warriors’ Heritage
The Three Kingdoms lived in harmony, but everything changed when the True Draco attacked… oh wait, wrong fiction. This main deck focused archetype unlocks its true potential by combining Beast Warriors of three attributes to act as both an aggro or a control strategy, depending on your perspective.
15 – World Legacy Generaider Boss

Adapted from CDP: Generaider Legacy
The Generaider boss archetype offers a unique take on the control concept, heavily involving Rank 9 Xyz monsters. But with the help of some World Legacy support, Link monsters can join the fray as well to help control the duel and keep opposing strategies on poor footing.
16 – Code Talker Matrix

Adapted from a Cancelled CDS Article.
The Code Talkers are omnipresent throughout the VRAINS era, but how can this Cyberse strategy adapt to the recent rule changes? This hard combo strategy aims to make the toughest of Link Monsters to win the day, especially now that the U-Link is less impactful! This build makes its debut in the tournament, never being featured in a CDS or CDP before, but it was designed as a concept in response to a request for a Cyberse article.
17 – Cynet Psy-Frame

Adapted from a Future CDS Article.
The Psy-Frame archetype brings control elements, while the Cyberse type can bring some much needed efficiency in unlocking Psy-Framelord Lambda. Will this digitized telekinetic control strategy stun the opponent from playing? This strategy makes its debut in the tournament, but it is intended to be the focus of a future CDS article on the site.
18 – Dino Evol-ution

Adapted from a Cancelled CDP Article.
Dinosaurs reigned supreme in the Jurassic era, but it’s time for them to evolve to the next stage. Utilizing an Evol engine, Dinosaurs can reach new heights of disruption when charged with taking the first turn of the duel, while still retaining the capability to rampage over an unprepared opponent in an aggressive OTK going second. This strategy makes its debut in the tournament, after being cancelled due to the very competitive nature of Dinosaurs following the release of Animadorned Archosaur.
19 – Time Thief Shark

Adapted from CDS: Time Thief Shark
Time travel with this R4NK Xyz Summoning-based strategy as you combine Psychic timelords with fish from the ocean depths. This is a disruptive strategy to its core, trying to prevent the opponent from gaining any momentum in the duel. Has it seen enough of the future to win the competition?
20 – Mayakashi Hydralander

Adapted from CDS: Ghost Meets Girl
The Mayakashi theme represents the undead element in the competition, bringing in Synchro summons and Synchro ladders! But this theme also covers the ‘Orbital Hydralander’ mechanic, representing strategies that want to use single copies of many different cards! This build is modernized from the approach originally put forth in the linked CDS article, in an attempt to be more optimized for the current gamestate.
21 – Adamancipator Megalith

Adapted from a Potential Future CDS Article.
These themes rock, so why not mash them together! This hybrid strategy Ritual Summons, Link Summons, Synchro Summons and… magnet warriors? This hyper combo strategy also accounts for the excavation game mechanic as well as being the representative for 60-card decks! Will it be enough to rock the world in this competition? This strategy makes its debut in the tournament, but it is currently a contender for a full article at a future date.
22 – Gimmick Puppet Xyz

Adapted from CDS: LD5 Gimmick Puppet
This DARK Machine archetype utilizes Rank 4 and Rank 8 Xyz Summoning, in addition to plenty of other gimmicky tricks. It is primarily an aggro strategy, with some combo elements. For this event, the decklist was updated, specifically to replace the Sky Striker engine with an Orcust engine.
23 – Ancient Gear Meklord

Adapted from the next CDS Article.
Adding another Machine-type representative to the tournament, the Meklord archetype combines with the Ancient Gears to provide a destructive time! Will the Ballista launch this hybrid strategy to new heights, or will it rust under the pressure of the competition? This strategy makes its debut in the tournament, but it is the focus of my next CDS article on the site.
24 – The World Legacy

Adapted from CDS: True World Legacy and CDS: World Legacy Revisited
The lore of the World Legacy archetypes is rich indeed, and all that lore is represented by the hybrid strategy combining the best of these archetypes. The Mekk-Knights, Orcust, and Crusadia unite to celebrate Link Summoning in this combo strategy. Will this theme rise to the occasion, or fall back to being just legends?
25 – F.A. Racecar Machines

Adapted from the next CDP Article.
Vroom Vroom, start your engines because the F.A. have arrived. Featuring Synchro Summoning, Link Summoning, and level-alterning mechanics, this machine theme takes a windier approach by involving the Mecha Phantom Beasts and Symphonic Warriors as well! This strategy makes its debut in the tournament, but it is the focus of my next CDP article on the site.
26 – Stagecraft of the Abyss Actors

Adapted from CDS: Stagecraft of the Abyss Actors and featured in CDP: Double Feature.
The stage is set for a dramatic entry of a Pendulum theme into the competition, so let’s put the spotlight on these fiends. Combined with their trusty Abyss Scripts, this combo deck has the potential to knock out its audition set in this competition, but will it break a leg and perform at the highest level?
27 – Rikka Aromage

Adapted from CDS: Rikka Aromage.
The garden flourishes with icy petals and fresh scents wafting through the trees. Will this Synchro Summoning/Link Summoning/Xyz Summoning Plant hybrid approach just be another pretty flower, or will it have enough competitive flair to bloom as a top contender?
28 – Infinite Qliphort ARMada

Adapted from CDS: The Qliphort ARM-ada.
The final Machine theme of the competition swings back as another Pendulum focused strategy, while also covering the Tribute Summoning mechanic. Featuring an infinite upgrade with a number of Infinitrack support cards, will this disruptive advantage-based deck be able to ride the rails all the way to the top? This strategy has been upgraded and re-balanced since its original posting.
29 – Supreme Red-Eyes

Adapted from CDS: Red-Eyes Revolution
There would be no sense hosting this competition without my most viewed article ever posted, so let’s bring in the Red-Eyes! This modernized Red-Eyes build focuses on all Extra deck summoning mechanics, including the ability to unleash Supreme King Z-ARC! Will that be enough for the final Dragon-type theme to inferno fire blast its opponents?
30 – Dragma Fusion

Adapted from CDS: Fusion Dragma
The last primarily Spellcaster theme of the event embodies every aspect of the Fusion Summoning mechanic. With help from the Shadoll and Invoked archetypes, who will be able to stand in the path of this control strategy?
31 – Nepthys Impcantation

Adapted from CDS: Sacred Impcantations.
Like the Phoenix itself, the Nephtys theme has been reborn yet again to take on the competition. With access to Winged Beasts and Spellcasters, this Ritual Summoning and Link Summoning combination may have enough control elements to hold a candle to the strongest themes in the competition! Or will its disciples leave empty-handed? This build has been modernized since its original posting to include new type support and a more streamlined build.
32 – Unchained Scrap

Adapted from CDS: Unchained Scrap.
The final seed of the competition combines Link Summoning with disruption and destruction, as the Unchained and Scrap archetypes combine. How will the Souls of Anguish and Rage be harnessed as the dark spirits swirl in the Scrapyards and Factories? This build has been modernized following the release of new Unchained support since its original posting.
