Once the game's first Contact Fusion and Union monsters, ABCXYZ are back stronger than ever thanks to several brand-new support cards and a Kaiba-exclusive Skill. The core gameplay revolves around leveraging B-Buster Drake 's infinite search ability and the Level 4 Machine/Light monsters to create an overwhelming card advantage. While the deck demands careful resource management and is locked to the Light type, its ability to set up an end board filled with negates and devastating Hyper Dragon Cannon machines will certainly make opponents wary.

Instructions for playing ABC (XYZ Union)
A few words about Deck
The history of the development of the ABCXYZ Union deck.
Although not officially classified as an "archetype" in Yu-Gi-Oh! standards, the ABCXYZ series of Machine/Light Machine cards boasts a fascinating and iconic history within the game:
2003 - The Legendary Beginning: The XYZ card series debuted in the Magician's Force box. The trio of X-Head Cannon, Y-Dragon Head, and Z-Metal Tank were the first Union and Contact Fusion monsters ever to exist in the game. They could flexibly fuse into two-material versions or create the main XYZ-Dragon Cannon – a card so cool that it had two different alternate artworks at the time. Associated with Seto Kaiba in Battle City and the Pyramid of Light anime, this card represents the childhood of many duelists.
2005 - The GX Era & VWXYZ Expansion: Received a major boost in Elemental Energy boxes with the introduction of the V-Tiger Jet and W-Wing Catapult. From here, players could craft the colossal monster VWXYZ-Dragon Catapult Cannon. This card series continued to shine on screen through the hands of Chazz Princeton in Yu-Gi-Oh! GX.
2016 - The golden age of meta dominance: Seto Kaiba's Structure Deck brought about spirit-oriented remakes: A-Assault Core, B-Buster Drake, and C-Crush Wyvern, along with the flagship ABC-Dragon Buster. The ABC deck truly became a dominant force in the meta throughout 2016-2017.
A peculiar combination with Ojama: Thanks to the Chazz Princeton character, XYZ received incredibly unique cross-support cards with Ojama and Armed Dragon. This "bizarre" combination gave rise to Armed Dragon Catapult Cannon and helped transform XYZ-Armed Dragon Ojamas into a highly effective deck for competitive play in tournaments.
2025 - A true revival: The Maze of the Master card box brings live, modern remakes of three original pieces: X-Cross Cannon, Y-Dragon Head (new version), and Zillion Tank, along with the new main carry XYZ Hyper Dragon Cannon.
The journey in Duel Links: The original XYZ cards, which had long been obscured in the Electric Overload box, along with the solitary contributions of B-Buster Drake and Union Scramble thousands of days ago, have only now, with the wave of new support cards combined with Kaiba's exclusive skill, truly exploded and had the chance to shine in their rightful place.
Monsters in the main deck
- Torque : acts as the main tuner, enabling us to perform Synchro maneuvers such as Ancient Fairy Dragon, Arc Light, Dawn Dragster, etc.
- Heavy Mech : revives Union monsters from the graveyard, usually Torque, to instantly Synchro Summon Arc Light. Even without Synchro Summoning, Heavy Mech is still very useful as an extender to prolong combo chains.
Spell/Trap
Extra Deck Monsters
However, as above, this card is also added to the extras thanks to its skin, so we can skip it.
Protector Whelp has the exact same function, but it's inferior to GPD because it can't utilize any of its effects.
Skill
Thanks to this skill, we can free up quite a few extra deck slots, assist with searching, and directly summon a Union spell/trap. Frankly, these are just some of the basic things a support skill for archetypes in general can do for a deck in the current Duel Links meta.
Combo/How to play
Combo ABC #4: Herald Arc Light combo (Using only 1 B-Buster card)
Conclusion
XYZ Union is not only a ticket to take players back to their childhood with Seto Kaiba's iconic machines, but also a true "Heavy-Combo" force with extremely high power in Duel Links.
Although it requires players to have the skill to memorize complex combo sequences, cleverly manage board space, and calculate how to dodge Hand Traps, the satisfying feeling of setting up a bunch of disruptions to throw at your opponent is undeniable. If you love resource-intensive gameplay and are passionate about destructive light machines, XYZ Union is definitely a deck worth investing in to climb the ranks.
