FREQUENTLY ASKED QUESTIONS

Is it worth opening Gym Heroes packs?

Based on current market prices, yes — the expected value is $59.82 per pack against a $4.99 pack cost, a positive return of +$54.83 on average. Keep in mind EV is a statistical average across many packs; individual packs vary significantly.

What is the hit rate for Gym Heroes packs?

About 75% — roughly 1 in 1 packs. This is the probability that your guaranteed rare slot pull is worth more than the pack cost on its own. The reverse holo slot adds additional value on top of this.

What is the best pull in Gym Heroes?

The highest expected-value card in Gym Heroes is Sabrina's Gengar, currently priced around $324.50. Chase cards like this drive most of a set's EV — a single pull can easily cover the cost of multiple packs.

How is pack expected value calculated?

Every booster pack contains a rare slot (one guaranteed rare or better) and a reverse holo slot (one random card from the set). We apply estimated pull rates to each rarity tier — Secret Rare ~4%, Ultra Rare ~7%, EX/V/ex ~14%, Holo Rare ~20%, Basic Rare ~55%. Within each tier, probability is split equally across all cards of that rarity. Each card's price is weighted by its pull probability and summed to produce the EV per pack. Pull rates are approximations based on community-verified data; actual rates vary by set print run and product type.

The Gym Heroes set was released on August 14, 2000 as part of the Gym series, containing 132 cards across multiple rarity tiers. At a pack price of $4.99, the estimated expected value is $59.82 per pack — a positive return of +$54.83 on average.
