Magic: The Gathering's closest audience match is Dungeons & Dragons at 0.83 — and no other Toys and Games brand appears in the top 10, with D&D Beyond (0.77) being the only fellow subcategory member.
The shape is broad: scores run from 0.83 down to 0.71 across the top 10 with no sharp drop-off, meaning the audience overlaps comparably with a wide range of entities. Video Game Franchises dominate the neighbor set — Dungeons & Dragons (0.83), Diablo (0.80), and World of Warcraft (0.73) form the core — but the top 10 extends well beyond gaming. Wizarding World of Harry Potter (0.76), a Movie Franchise, sits nearly as close as Critical Role (0.76), a Podcast. Challengemtv (0.73), a TV Show, rounds out the group. The cross-kind spread is notable: the top 10 spans Video Game Franchises, Toys and Games, a Movie Franchise, a Podcast, and a TV Show — no single subcategory accounts for more than three of the ten slots. The audience shape is less "card game players" and more a broad fantasy-and-fandom constituency that moves fluidly across tabletop, digital, and media properties.
This breadth suggests an audience that doesn't cluster tightly around any one entertainment format, but instead tracks a shared imaginative register across games, shows, and franchises.
