"The Mekk-Knights are World Legacy warriors who exploit columns—the vertical arrangement of cards on the field. They Special Summon themselves to columns containing two or more cards, punishing the opponent for setting backrow. Each color represents a different spectrum of power, and their column awareness creates a uniquely spatial form of combat."

Crowned by the World Chalice
I · The forest
  1. In a world ruled by the seven Mekk-Knights and plagued by the insect-like Krawlers, a hidden village of humans lived in the Celestial Forest, shielded by a sacred staff. Its heir was Ib; with her lived her brother Ningirsu, their friend Auram and the dragon whelp Imduk.
  2. Following a mysterious voice, Ib found a giant structure that woke to her staff's glow: the World Chalice. A small fairy, Lee, asked the children to gather the seven scattered World Legacies and save the world from the Great Darkness.
  3. At the World Armor, the seven Mekk-Knights appeared in the colors of the rainbow, caught Ib in energy her staff could not resist, and vanished with her.
  4. When Ib wondered aloud whether they should be fighting the Mekk-Knights at all, Lee dropped her adorable face. She took over Ib's body as Iblee, stripped the others of the Chalice's power and tried to kill them, but the Mekk-Knights turned against her.
  5. Iblee turned the Mekk-Knights' cores into Knightmares, beasts of myth. Ningirsu cut Mermaid down in one blow and drew the rest onto himself, so that Auram could chase her.
  6. As Iblee raised a sword over the wounded Auram, Imduk leapt in front of her and held Lee back. For a moment Ib woke, saw what was happening, and turned the sword on herself.
  7. Ages before, humanity had unearthed the Key, a relic left by God. The scientist Lee believed it could grant the power of God, and even call forth the Great Darkness.
  8. Her team, the Crusadia, built a Mekk-Knight around the Key, and switching it on scorched the Earth black, as Lee had planned. Seven support Mekk-Knights destroyed it and were ordered to hold humanity back while the Earth healed. Lee's body died, but her soul hid in the World Chalice.
  9. Years later, Auram woke a Krawler and melded minds with it. Learning the world's secrets, he united its tribes into a new Crusadia alliance and took up the power of the World Crown.
  10. Ningirsu had taken Ib's body. To see her smile again, he built her a mechanical body and raised the tower Babel, guarded by the Orcust, machines left over from his experiments.
  11. Holding Auram back with his Orcust hordes, Ningirsu dropped the World Wand from orbit onto the Earth's core, to wake the World Ark and bring Ib back.
  12. Imduk gave his life to shield his friends from the impact. The World Ark remade him as Andrake, and every World Legacy woke as a dragon: the Guardragons.
  13. But when Ib's soul returned to the mechanical body, Lee seized it as Idlee and woke Deus X-Krawler to make herself a god. Imduk, consumed by death, stood in her way as Mardark.
  14. The World Chalice, now Guardragon Justicia, flew in from the Celestial Forest and merged with Ib: she was reborn as Ib the World Chalice Justiciar. The doll, who had named herself Galatea, had given her own soul in Ib's place.
  15. Ib called Imduk's soul back from Mardark, and he became Almarduke. Granting Galatea's dying wish, Ningirsu forged Dingirsu from Babel's remains and his Orcust army, and it destroyed Idlee.
  16. Lee's soul merged with the World Gears, and their power ran wild. Carrying the Key and every World Legacy, Auram awoke as the World Hero: Mekk-Knight Crusadia Avramax.
  17. Instead of destroying the vessel of God, Auram became one with it as Avida, Rebuilder of Worlds, and rebuilt the world he had lived in, with everyone lost in the war.
  18. A girl, Lib, woke beneath a calm night sky and set out on a journey with Imduk, guided by the faint light of the sword she held.

Executive Summary

The Mekk-Knight archetype offers a unique, reactive playstyle centered on column-based gameplay. As key figures in the "World Legacy" lore, they manifest on the field by capitalizing on the opponent's board presence, making them a premier "go-second" strategy designed to break established fields. Their strength lies in turning the game board itself into a puzzle, forcing opponents to reconsider every card placement lest they create the very columns of light from which these powerful knights emerge to generate overwhelming advantage.

The Main Deck Knights

Mekk-Knight Blue Sky
Missing: 20537097

Blue Sky

The primary advantage engine. When summoned, it searches for "Mekk-Knight" monsters equal to the number of opponent's cards in its column, making it devastating against an established board.

Mekk-Knight Purple Nightfall
Missing: 28692962

Purple Nightfall

The most versatile knight. Its Quick Effect banishes a Mekk-Knight (usually itself) to search another, dodging effects and ensuring a constant flow of resources.

Mekk-Knight Indigo Eclipse
Missing: 92204263

Indigo Eclipse

The core of the control strategy. Its Quick Effect moves a Mekk-Knight to another column, enabling mobile negation when paired with "World Legacy's Secret".

Girsu, the Orcust Mekk-Knight
Missing: 69811710

Girsu, the Orcust

The deck's go-first enabler. It creates a column by summoning tokens and sends a "World Legacy" card to the GY, setting up powerful Extra Deck plays.
