The final October edition of the Wolfpack Collectibles TCG Card Show lands on Tuesday, October 27, 2026 at Diamond 9 Sports in Placentia, four days before Halloween weekend, when the OC Card Show at the OC Fair & Event Center and TheSportsBase Fountain Valley show both run. Treat this Tuesday as the warm-up: a free, relaxed evening to trade, restock and get a read on prices before the big weekend.
What you will find: a trading card game marketplace led by Pokemon, with sellers carrying current-set singles, special illustration rares, vintage holos, Japanese product, sealed boxes and graded cards from PSA, CGC and Beckett. One Piece Card Game is strongly represented, along with Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana and Dragon Ball Super. Seasonal items tend to appear this week too, such as Halloween-themed Pokemon promos and spooky-themed bundles. Diamond 9 Sports keeps its shop case of MLB, NBA, NFL and NHL cards open for sports collectors.
The show runs from 3:00 PM to 9:00 PM. Admission is free. Vendor tables are 30 dollars and must be reserved through the Diamond 9 Sports website in advance.
Diamond 9 Sports is at 1850 N Placentia Ave, Placentia, CA 92870, in the shopping center at Yorba Linda Boulevard just east of the 57 Freeway, with free parking in the lot out front. From Santa Ana it is about 20 minutes via the 55 and 57 outside of peak traffic.
Who should come: Pokemon and One Piece players and collectors of all ages, families looking for a free weeknight activity, traders who want a consistent weekly venue, and first-time sellers who want an inexpensive table. Anyone planning to attend the Halloween weekend shows can use this night to scout what local vendors are carrying and what they are paying for collections.
Tips: come at 3 PM for the best selection or after 6 PM for the most active trading. Bring a sorted binder, a want list and small bills. If you are selling, price sharply; buyers know the big weekend is coming and will hold out for deals. Ask the Diamond 9 staff about any in-store Halloween promotions or box openings happening that week. Keep an eye on the Wolfpack Collectibles Instagram for the vendor lineup and any costume-related giveaways. If you are bringing children, this is one of the more kid-friendly Tuesdays of the year, since several regular vendors hand out free packs or promo cards to younger collectors around Halloween, and the open tables usually host a casual Pokemon game or two that beginners are welcome to join. Sellers should note that the Halloween weekend shows pull a lot of the local buying power, so cards priced to move on October 27 will do better than cards priced to sit.
