Gym Challenge Master Set Checklist & Cost

Variants in the Gym Challenge master set

Most of the Gym Challenge master set comes from two print runs: Normal 1st Edition and Normal Unlimited at 112 slots each, with the holo cards repeated the same way as Holo 1st Edition and Holo Unlimited at 20 slots each. A 1st Edition print carries the 1st Edition stamp and an Unlimited print does not, so every card needs a slot for each. The remaining slots are one-offs: a Holo Energy Symbol Error, a Holo Jumbo Winner, a Normal Text Error and a Normal Wotc print. Those four are single slots, but each is its own space in the binder.

Where the Gym Challenge master set's cost sits

As of October 24, 2026, 263 of the 268 slots in the Gym Challenge master set carry a price. The master set cost leans heavily on the top end: the ten most valuable slots hold 40 percent of the total value, while the lower-value half of the priced slots adds up to only 5 percent. By finish, holo slots account for 72 percent of the value and normal slots for 28, even though normal slots far outnumber holos. Condition matters too, since an LP and up master set totals 15 percent below the Near Mint figure and an MP and up set sits 18 percent below it.

Hardest Gym Challenge master set slots

Four of the five hardest slots in the Gym Challenge master set are holos, and one is a surprise. Blaine's Charizard in Holo 1st Edition ranks first by value, followed by Erika's Venusaur in Holo 1st Edition. Blaine's Charizard in Holo Unlimited takes third, then Sabrina's Gengar, a Rare, in Normal 1st Edition, a variant slot of a card that is not even a holo. Rocket's Mewtwo in Holo Unlimited rounds out the five. Together these slots hold 24 percent of the master set's total value, and three of them are variants rather than a card's main print.
