Gym Heroes
Booster Box no-chase EV calculator

Estimate the no-chase value of one English Gym Heroes booster box: 36 packs with 11 card positions each. Values use historical generated local TCGplayer snapshots. Unlimited is the default; select 1st Edition for its separately priced full-box comparison.

Chase branches are excluded: holo rares, EX/GX/V/VMAX/VSTAR, secret rares, Shiny/Radiant/Trainer Gallery, illustration, hyper, ACE SPEC, and other premium rows do not contribute to this baseline.

Calculation order: ordinary pack contents are assigned to card rows first, then disabled pools and optional Sift filtering are applied afterward. Disabled rows do not backfill into other cards.

No-chase baseline

Gym Heroes resolves six ordinary Common cards, one Basic Energy, three Uncommon cards and one Rare position in each 11-card pack. A contemporaneous August 3, 2000 Wizards representative Q&A states that one of the seven Common cards is Energy. The six Energy remain Common by publisher-checklist classification although their physical faces have no rarity mark. Uniform weights within 42 ordinary Common, six Energy, 42 Uncommon and 23 ordinary Rare are modeling assumptions. This documented no-chase comparison excludes the 19 Holo identities before normalizing the ordinary Rare slot.

The mandatory Basic Energy position is included. Standalone promotional inserts, code cards and other non-game inserts are outside this product. Energy is a physical-slot label; the Rarity column keeps its separate publisher-checklist Common classification.

Loaded pools: waiting for card data.

Sift is a price floor. Row tinting always uses the Sift value; EV only uses it when Use Sift in EV is checked.

Release-specific model analysis

What drives Gym Heroes Booster Box

Product profile. This booster box resolves 396 card positions across 113 named outcomes. The model snapshot dated June 10, 2026 contains 48 Common, 42 Uncommon, 23 Rare. Its largest slot groups are 42 nf common, 42 nf uncommon, 23 rare slot rare, 6 basic energy. Every listed outcome contributes to the published baseline unless the visitor applies a post-draw filter.

Largest modeled weights. Fighting Energy #127/132 (6.00 expected per booster box), Fire Energy #128/132 (6.00 expected per booster box), Grass Energy #129/132 (6.00 expected per booster box), Lightning Energy #130/132 (6.00 expected per booster box), Psychic Energy #131/132 (6.00 expected per booster box). These are frequency leaders in the product model, not a promise that any individual opening will contain them.

Release-specific card examples. Blaine's Charmander #061/132, Blaine's Growlithe (35) #035/132, Blaine's Quiz #1 #097/132, Water Energy #132/132, Brock's Golem #020/132, Brock's Onix (21) #021/132, Brock's Rhyhorn (22) #022/132, Brock's Sandslash #023/132. Seeing the named pool makes it possible to compare this release with adjacent sets instead of treating every sealed product as the same generic pack calculation.

Reference snapshot value concentration. At the TCGplayer Market snapshot dated August 12, 2026, 113 modeled outcomes have a usable direct or documented fallback price. The largest deterministic contributions come from Rocket's Snorlax #033/132 ($272.00), Sabrina's Haunter #058/132 ($151.89), Lt. Surge's Pikachu #081/132 ($128.57), Misty's Psyduck #054/132 ($77.81), Lt. Surge's Raichu #028/132 ($74.46). Together those five rows account for 21.7% of the modeled gross value. This dated reference does not update with the live calculator's prices or Sift settings.

The baseline product model is constructed first, including any documented chase exclusions. The calculator then draws the complete baseline product. Included-pool controls and optional Sift evaluate that completed draw afterward and do not alter its collation.

Selling Fees

Per-row net EV uses percentage and transaction fees. Per-order processing is controlled in purchase settings.

Generated Pokemon price snapshots support Market, Low, and Direct Low pricing for EV.
Rows below Sift are removed from EV only if the toggle below is on.

EV Range (Monte Carlo)

Runs per summary update; low and high are central quantiles from product openings.

Purchase EV

Whole boxes only (0–1,000); fractional and out-of-range input is normalized before calculating.
