October opens with the Wolfpack Collectibles TCG Card Show on Tuesday, October 6, 2026 at Diamond 9 Sports in Placentia. It comes two days after one of the busiest card weekends of the fall in Orange County, when the USA Card Show in Irvine, TheSportsBase show in Fountain Valley and the Tustin Tiller Days card show all ran at once, so expect vendors to arrive with fresh inventory they bought over the weekend and collectors to arrive with cards they want to flip.
The show is built around trading card games. Pokemon takes up most of the room, with sellers offering current Scarlet & Violet and Mega Evolution singles, special illustration rares, vintage Base Set through Neo holos, Japanese boxes and promos, and graded slabs across every price point. One Piece is the second-largest game here, and Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana, Dragon Ball Super and Union Arena sellers show up most Tuesdays. Diamond 9 Sports keeps its shop case open, so there is a solid sports card selection for MLB playoff season, especially Dodgers and Angels, plus NBA and NFL rookies.
Hours are 3:00 PM to 9:00 PM, and admission is free. Vendor tables cost 30 dollars and are reserved online through the Diamond 9 Sports table reservation page. There is no ticketing, no early-bird tier and no age restriction; kids are welcome with a parent.
The venue is Diamond 9 Sports, 1850 N Placentia Ave, Placentia, CA 92870, on the south side of Yorba Linda Boulevard just east of the 57 Freeway. Parking is free in the center's surface lot. From Santa Ana, take the 55 north to the 57 north and exit at Yorba Linda Boulevard; the drive runs 20 to 30 minutes depending on the hour.
Who should attend: Pokemon and One Piece players who need singles before a weekend tournament, families with young collectors, binder traders who value a predictable weekly meetup, and first-time sellers who want to test the waters without paying convention-scale table fees. Sports-only collectors will find the shop case worth a look but should not expect a full sports show.
Tips: with the weekend shows just behind it, October 6 is a good night to sell, since vendors are restocking and will pay for clean inventory. Bring cards sleeved and sorted, know your rough market values, and be willing to trade rather than insist on cash. Arrive at opening if you want first pick; arrive after 6 PM if you want the most people to trade with. Small bills help at dollar-bin tables, and a portable light or loupe helps when checking surfaces on higher-end cards.
