Behind every community-built retro format is a real historical event, and Edison Format's is a particularly well-documented one: the 75th Shonen Jump Championship, held in Edison, New Jersey, in April 2010.
Understanding what actually happened at that tournament, who won, and what the top decks looked like adds real context to why the community chose to build an entire format around recreating that exact moment in the game's history.
This guide walks through the tournament itself, its record-setting attendance, its championship match, and how its legacy shaped the format that carries its name today.
It builds on the format overview and the Goat Format comparison published earlier in this series.
The 75th Shonen Jump Championship was held at the New Jersey Convention and Exposition Center in Edison, New Jersey, over April 24 and 25, 2010, drawing 2,175 duelists, making it the largest Shonen Jump Championship held up to that point.
That scale matters for the format built around it: a tournament of that size produces a metagame snapshot with real statistical weight, reflecting what a huge cross-section of competitive players across North America were actually playing at the time.
Jeff Jones won the event piloting a Quickdraw Dandywarrior deck, a Quickdraw Plant build, defeating Reinaldo Lainez, who reached the finals with a Doomcaliber Gadget deck, in the tournament's final match.
The semifinal round also featured a notable feature match between Billy Brake and Jeff Jones, underscoring how competitive and closely contested the top of the bracket was at an event of this size.
The tournament's top cut featured a genuinely diverse spread of strategies beyond just the eventual finalists, including Lightsworn, Blackwing, Gladiator Beast, Frog Monarch, Hero Beat, and Machina Gadget, alongside several rogue strategies that also performed well.
This diversity is a big part of why the community chose this specific event as the format's foundation; a metagame with over a dozen competitively viable strategies gives a retro format far more deckbuilding room than a snapshot dominated by one or two decks.
Rather than picking an arbitrary banlist date, Edison Format's organizers tied the format directly to this specific, well-documented tournament, giving the community a genuine historical touchstone rather than a purely mechanical cutoff point.
The March 2010 banlist and the Duelist Pack: Kaiba card pool cutoff both align closely with the timing of this event, reinforcing the connection between the format's rules and the real tournament it commemorates.
Modern Edison Format's metagame still closely mirrors the archetype diversity seen at the original 2010 event, with Blackwing, Hero Beat, and Frog Monarch all remaining relevant, competitive choices for players building decks today.
This continuity is part of the format's appeal: playing Edison Format today means engaging with essentially the same strategic landscape that thousands of players navigated at a real tournament well over a decade ago.
Official tournament coverage from the event, including feature match write-ups and decklists, remains archived and searchable, giving today's Edison players a genuine primary source for understanding exactly how the format's namesake tournament actually played out.
This kind of historical documentation is relatively rare for a card game tournament from this era, and it is a big part of what makes Edison Format feel grounded in real competitive history rather than an abstract, arbitrarily chosen ruleset.
An attendance of 2,175 duelists at a single tournament remains an impressive figure even by today's standards, and it was a genuine record at the time, underscoring just how large Yu-Gi-Oh's competitive scene had grown by the spring of 2010.
That scale is precisely why the event makes such a strong foundation for a retro format; a metagame drawn from thousands of competing decks reflects real, tested strategic diversity rather than a small, potentially unrepresentative sample of top players. Few other community-built formats can point to this level of documented, large-scale competitive data behind their founding snapshot, which gives Edison Format a credibility that a more arbitrarily chosen banlist date simply could not match.
