The Power Card Show – Fall edition lands at the Mesa Convention Center on Saturday, October 10 and Sunday, October 11, 2026, bringing the East Valley's premier card-and-collectibles show back for a cooler-weather weekend. (Dates are projected from the operator's seasonal cadence after its Summer Splash edition; confirm on powercardshow.com before you go.) Billing itself as the East Valley's best card show and running since 2021, Power Card Show packs 250+ vendor tables of sports cards, TCGs, slabs, and pop-culture collectibles into a comfortable convention-center floor that's big enough to dig in but not so huge it wears you out.
This is a two-day weekend show, typically running Saturday and Sunday daytime hours — check powercardshow.com for confirmed times, ticket pricing, and any breaker or signer programming. Admission is collector-friendly with single-day and weekend options.
The Mesa Convention Center at 263 N Center St sits in downtown Mesa with on-site and nearby parking and easy access from US-60 and Loop 101/202, plus the Valley Metro light-rail line a short walk away.
