Pokémon TCG Gym Heroes and Gym Challenge (2000): Which WOTC Leader Set to Collect First
By Dexhaul Team · September 15, 2026
The WOTC Gym sets are where Pokémon cardboard finally put the Gym Leaders themselves on their own cards.
Released two months apart in 2000, Gym Heroes (August 14) and Gym Challenge (October 16) each contain 132 cards and feature Pokémon belonging to the eight Kanto Gym Leaders.
Both sets draw from the full roster: Brock, Misty, Lt. Surge, Erika, Koga, Blaine, Sabrina, and Giovanni all appear in both releases. What separates them is the holo rare lineup and one pivotal addition in Gym Challenge: Rocket's Pokémon, with Giovanni's organization producing its own cards alongside the Leaders.
If you are building a WOTC collection and want to add the Gym chapter, the choice between starting with Heroes or Challenge comes down to which ceiling matters more to you.
Gym Heroes: Sabrina's Gengar and the Broader Holo Spread
Gym Heroes has 14 holo rares, the widest spread of the two sets. The flagship is Sabrina's Gengar (14/132), a Ghost-type holo from the Saffron City psychic specialist that sits at $451–$600 raw depending on grade and seller.
Sabrina's Gengar earns its premium from three converging factors: character demand for Gengar (consistently one of the most collected Pokémon), Sabrina's cult following from the anime, and the card's relative scarcity in PSA 9 and above populations. A raw copy in Near Mint runs $451–$600. PSA 7 copies hover around the same range in some listings, which tells you graded supply is tight at high grades.
Erika's Dragonair (4/132) is the secondary holo chase in Heroes at $131.70 raw. Dragon-type collector interest has grown since Scarlet and Violet.
Gym Heroes Sealed: The More Accessible Pack
Gym Heroes 1st Edition booster packs run around $499. Unlimited packs from the same set are significantly lower. The 1st Edition stamp carries the same function here as in Base Set or Jungle: it signals the first production run, before WOTC switched to Unlimited printing.
That $499 price is notably lower than Gym Challenge's 1st Edition equivalent, despite Heroes coming out first. The reason is print run: Gym Challenge's 1st Edition run was smaller, making those packs the rarer item independent of what's inside them.
Gym Challenge: Blaine's Charizard and the Villain Layer
Gym Challenge has one card that anchors its entire collector profile.
Blaine's Charizard (2/132) is the only holo in the entire WOTC era that depicts a Charizard with entirely different stats and attacks from the Base Set Charizard (4/102). Every other WOTC-era Charizard holo, including Base Set 2 and Legendary Collection, reprints the same 4/102 art with the same HP and moves.
Blaine's Charizard is distinct: it belongs to Blaine specifically, carries different attacks (Controlled Burn at 30+, Flame Jet at 80+), and sits at 90 HP versus the Base Set Charizard's 120. Collectors targeting a complete WOTC Charizard holo collection need three cards: Base Set, the reprint editions, and Blaine's.
Unlimited copies of Blaine's Charizard run $389–$413 in Near Mint condition. A PSA 8 Unlimited graded copy hits $950.
1st Edition is where the ceiling opens: PSA 8 1st Ed copies list at $2,019, and a PSA 9 1st Ed copy lists at $3,650. The raw-to-graded spread is among the steepest in the Gym sets, driven by how difficult the dark holo foil centering is to grade well.
Rocket's Mewtwo: The Overlooked Gym Challenge Holo
Rocket's Mewtwo (14/132) is the secondary holo chase in Gym Challenge and a card that frequently gets conflated with the wrong listing. The Team Rocket set released earlier in 2000 has Mewtwo as a card, but it is a non-holo common at 1/82 with completely different mechanics.
Rocket's Mewtwo in Gym Challenge is a distinct Holo Rare with Giovanni's Rocket organization framing, different HP (70), and its own attack suite. Buyers searching for "Rocket Mewtwo" without checking card numbers frequently pay for one when expecting the other.
Raw Unlimited copies of Rocket's Mewtwo (14/132) run $126.61–$180.75. A BGS 9 graded copy lists at $615. For collectors who want a Gym Challenge Mewtwo without the Blaine's Charizard outlay, it's the most direct entry.
Gym Challenge Sealed: Higher Pack Premiums, Smaller Run
Gym Challenge 1st Edition booster packs run $750–$881, roughly 50–75% above Gym Heroes 1st Edition packs at $499.
This price gap is counterintuitive. Gym Challenge has the higher-ceiling pull in Blaine's Charizard. You would expect the pack containing the bigger card to cost more because of demand.
In practice, the premium comes from supply: Gym Challenge had a smaller 1st Edition print run than Gym Heroes. The packs themselves are rarer as physical objects, separate from what they might contain. Gym Challenge Unlimited packs run $599.
The Trainer Card Sub-Collect Most Collectors Skip
Both sets contain Trainer cards depicting the Gym Leaders by name as full-art-style cards at higher set numbers. Misty (20/132), Brock (15/132), Erika (16/132), and Lt. Surge (18/132) appear as Trainer cards in Gym Heroes.
Giovanni (18/132), Koga (106/132), Blaine (105/132), and Sabrina (110/132) appear in Gym Challenge. These are separate cards from the Leaders' Pokémon holos.
Most collectors chasing holo rares never complete the Trainer side of either set. A Brock (15/132) Unlimited Trainer card runs $69.99, the same price as a Brock's Rhydon 1st Edition holo, but with a fraction of the search volume. It's the version of each leader that most directly depicts them as a person, and in 2000 that was genuinely novel for the TCG.
Completing both the Leader Pokémon holos and the Leader Trainer cards from both sets gives you the most complete WOTC Gym chapter possible. Very few WOTC-era collections reach that depth.
Which Set to Start With
Start with Gym Challenge if your priority is a single high-ceiling card. Blaine's Charizard is the definitive pull of the entire Gym chapter, and its 1st Edition range ($2,019–$3,650+ graded) puts it in a tier above anything in Gym Heroes. Gym Challenge also has a tighter holo roster (12 holos vs Heroes' 14), which makes completing the holo set more achievable.
Start with Gym Heroes if you want broader holo coverage at lower average cost per card. Fourteen distinct holos spread across more characters, and the sealed pack entry point ($499 1st Ed) is lower than Gym Challenge's $750. Sabrina's Gengar at $451–$600 is the Heroes ceiling, which is meaningful but not in the same bracket as Blaine's Charizard 1st Edition graded.
Both sets derive from the 1998 Japanese Gym Expansion series. The Gym sets are less searched than Base Set, Jungle, or Fossil, and singles still surface at prices that feel undervalued for cards this old.
