Did you know that despite their high price, Japanese Pokémon TCG booster boxes do not always contain the most desirable cards? No, an Eevee Heroes booster box from the Japanese Pokémon TCG Sword & Shield set series does not promise a secret rare card. While recent Japanese sets often include promises for certain high-value cards, such as a Super Rare, the box structure for Eevee Heroes follows an older plan. Its assurance sticks to 1 Super Rare card or better and 2 VSTAR cards, but it contains no clear promise for a secret rare card

Understanding Pokémon TCG Booster Box Guarantees

Japanese Pokémon TCG booster boxes, especially those from the most recent Scarlet & Violet expansions, usually feature fixed pull rates for specific card rarities in each box. The Pokémon Company sets these rates to ensure people who buy the cards feel they receive value. For example, main expansion boxes in 2025 promise things like 1 Super Rare or better (which perhaps include Special Art Rares or Ultra Rares), 1 ACE SPEC card, 3 Art Rares, as well as 4 Double Rares.
Eevee Heroes , which came out in 2021 as a Sword & Shield high-class pack focusing on Eevee evolutions, came before these set rates. The cards in the box follow the rules set during that time: 1 Super Rare card or better, 2 VSTAR cards, in addition to 4 V cards per box.

What is a Secret Rare Card?

A secret rare card is one whose set number goes past the official count for the set. People often look for these cards because they feature unique artwork, special texture, or highly collectible Pokémon.

Eevee Heroes vs. Modern Sets: A Guaranteed Comparison

To show how guarantees developed, here is a list comparing Eevee Heroes to some main expansion and high-class boxes. Data shows documented pull rates from Japanese sets — secret rare cards never receive an explicit promise across any of the products listed.
[1]

Set Type Example Sets Booster Box Guaranteed Hits
Eevee Heroes (SWSH High Class) Eevee Heroes, Paradigm Trigger 1 Super Rare card or better, 2 VSTAR cards, 4 V card
Modern Main Expansions (SV Era) Super Electric Breaker, Paradise Dragona, Stellar Miracle 1 Super Rare card or better (eg, Special Art Rare/Ultra Rare), 1 ACE SPEC card, 3 Art Rares, 4 Double Rare
SV High-Class Packs Black Bolt/White Flare, Pokémon 151 1 Super Rare card or better (eg, Special Art Rare/Black White Rare), 1 Master Ball Reverse Holo card, 3-4 Art Rares, 4 Double Rare
Specialty Packs Shiny Treasure ex, Terastal Festival Varies: eg, 1 Shiny Super Rare card, 3 Baby Shinies, 9 Double Rares (Shiny Treasure ex

Key Insight — Eevee Heroes lacks the ACE SPEC card or extra Art Rare card promises of newer sets. The box slot for a Super Rare card does not require a secret rare card shows up there. In all Japanese boxes, “God Packs” — packs with lots of secret rare cards — remain unguaranteed and rare (1 pack in 1,000 or more packs).

Pull Rates and Realistic Expectations

Japanese boxes offer better chances for certain cards because they set fixed rarities, but secret rare cards distribute based on chance. English boxes, in contrast, offer no such promises per box, making Japanese products much easier to figure out for those who collect the cards.
[5] For Eevee Heroes specifically:

Super Rare card or better — You get one in every box. Perhaps this means secret variants like full arts, but the box does not say it has to be a “secret” card.
[1]
No God Pack Assurance — These very lucky pulls happen but the box does not promise one

Modern Japanese packs sometimes promise rarities in each pack (eg, V cards in earlier sets), but Eevee Heroes focuses on the cards promised in the full box.

Do I Always Get a VSTAR Card in Eevee Heroes?

Yes, an Eevee Heroes booster box promises you receive 2 VSTAR cards.

Ranking Japanese Booster Boxes by Guarantee Strength

For those who prioritize assured, high-value pulls, here is a clear ranking of some sets based on the number and rarity of promised cards (higher rank = stronger promises). Eevee Heroes ranks lower because it follows an older plan that focused on VSTAR cards.
[1]

Rank Set Category/Example Total Promised Hits Standout Features Why It Ranks Here
1 Terastal Festival (High Class) 14+ 1 Special Art Rare, 1 ACE SPEC card, 9 Double Rares, 3 Reverse Holo cards
[1] Highest total number and best rarity cards.
2 Modern Main Expansions (eg, Stellar Miracle) 9 1 Super Rare card or better, 1 ACE SPEC card, 3 Art Rares, 4 Double Rares
[1] Balanced, consistent high-value pulls.
3 Shiny Treasure ex (Specialty) 13 1 Shiny Super Rare, 9 Double Rares, 3 Baby Shinies
[1] Strong focus on shiny cards, high total number.
4 Pokémon 151 (High-Class) 9 1 Super Rare card or better, 1 Master Ball Reverse card, 3 Art Rares, 4 Double Rares
[1] Solid pulls but fewer art rares.
5 Eevee Heroes (SWSH High Class) 7 1 Super Rare card or better, 2 VSTAR cards, 4 V cards
[1] Reliable basics, lacks the ACE/Arts boost.

This list puts the clear promises above stories of lucky pulls. It favors sets where the Super Rare card slot offers the chance for a secret rare card along with a high total number of promised cards.
[1]

Final Takeaway for Collectors

Eevee Heroes gives good value through its promises that fit the time it came out, but it does not promise a secret rare card — unlike the clear promises for a Super Rare card or better found in 2025 sets. You must always check the print details and differences between regions, as the promises apply only to Japanese products.
[1][5] For the best chances, aim for newer main expansions that include ACE SPEC cards.

FAQ
Do English Pokémon TCG booster boxes guarantee a secret rare?

No. English Pokémon TCG booster boxes contain no fixed promises for any specific rarity, including secret rare cards. Pull rates in English sets depend completely on chance, which makes them less predictable than the Japanese boxes. <a href="https://packtoria.shop/category/pokemon">Pokémon TCG Cards for Sale</a>

What is the best Japanese set for guaranteed pulls?

Based on the number and rarity of promised cards, high-class sets like Terastal Festival currently offer the strongest guarantees, promising multiple high-tier cards (eg, Special Art Rares, also ACE SPEC cards) per box.

Are "God Packs" guaranteed in Eevee Heroes?

No. "God Packs" (packs that contain many secret rare cards) happen by chance and are very rare. No Japanese Pokémon TCG booster box promises a "God Pack."
