Japanese High Class packs explained: VSTAR Universe, Shiny Treasure ex, Terastal Festival ex, Mega Dream ex

High Class is a Japanese product category whose specifications vary by set. The four examples here have ten cards per pack and ten packs per box. Compare their secret lists, pack contents and stated guarantees before choosing a box.

In short

The four High Class sets covered here have 10 cards per pack and 10 packs per box — 100 cards. Most regular Japanese packs hold 5 cards and most regular boxes 30 packs; Black Bolt and White Flare are 7 cards, 20 packs.
A guaranteed Pokémon ex is different from a guaranteed SSR or SAR per box. Check the official specification for the exact set; do not transfer guarantees between sets.
The secret list is the point: 90 cards above the total in VSTAR Universe, 170 in Shiny Treasure ex, 50 in Terastal Festival ex, 57 in Mega Dream ex.
The four sets here were released in December 2022, December 2023, December 2024 and November 2025. Those dates do not define every High Class release.
The English edition printed the first three as special sets without booster boxes — Crown Zenith, Paldean Fates, Prismatic Evolutions. The Japanese box is the box.

What a High Class pack is

High Class pack (ハイクラスパック) is a Japanese product category. In the four sets covered here, each pack holds ten cards instead of the usual five, and the box holds ten packs instead of thirty — 100 cards in a box. These four sets combine reprints with secret cards and new artwork. Pack size is not the definition: the official TAG TEAM GX All Stars specification lists 11 cards per pack. A stated Pokémon ex guarantee also does not establish an SSR or SAR guarantee per box.

The numbered part of the list is mostly reprints of the year's playable cards; the part above the total is new artwork. That balance is why a High Class box is opened differently from a regular one: less for the deck, more for the wall.

The four in the vault

VSTAR Universe (VSTARユニバース, S12a) — 2 December 2022. 262 cards: 172 numbered, 90 secret — 37 AR, 35 SAR, 14 SR, 4 UR. The set where AR and SAR were first printed.
Shiny Treasure ex (シャイニートレジャーex, SV4a) — 1 December 2023. 360 cards: 190 numbered, 170 secret — 129 S, 18 SSR, 4 AR, 5 SR, 8 SAR, 6 UR. The official product page advertises guaranteed Pokémon ex. That statement does not establish one SSR in every box.
Terastal Festival ex (テラスタルフェスex, SV8a) — 6 December 2024. 237 cards: 187 numbered, 50 secret — 12 SR, 33 SAR, 5 UR. One Pokémon ex in every pack; no Art Rares, the SAR block is the set.
Mega Dream ex (MEGAドリームex, M2a) — 28 November 2025. 250 cards: 193 numbered, 57 secret — 20 AR, 9 SR, 10 MA, 17 SAR, 1 MUR. The first High Class pack of the MEGA era.

Charizard VSTAR SAR 212/172, Japanese Pokémon card — Four High Class packs, four years: VSTAR Universe (2022), Shiny Treasure ex (2023), Terastal Festival ex (2024), Mega Dream ex (2025).

High Class box, regular box

The table compares typical regular expansions with the four High Class sets in this guide. These four have 100 cards across 10 packs; many regular Japanese boxes have 150 cards across 30 packs. Specifications vary by set. A complete set list describes the cards that exist, not the contents of a particular box, and cannot establish rarity guarantees or pull rates.

Not every off-cycle Japanese set is High Class. Heat Wave Arena (SV9a), for instance, is an enhanced expansion: 5-card packs, 30 to a box, released between the main sets.

What the Art Rares are for

A High Class set is where the year's Pokémon get their full-illustration cards. VSTAR Universe carries 37 Art Rares and 35 Special Art Rares; Mega Dream ex carries 20 and 17. These are the cards most collectors are after, and they are the reason the rarity guide matters here more than anywhere: the number above the total tells you which block you are holding before you find the mark.

The top of the list

Across these four sets you will find gold UR cards (VSTAR Universe has 4, Terastal Festival ex 5, Shiny Treasure ex 6), the shiny SSR block in Shiny Treasure ex, and the single gold MUR in Mega Dream ex. Consult the exact set list for their numbers and positions. They are printed in the same ten-card packs as everything else.

Japanese box, English special set

The English edition did not print these as regular expansions. VSTAR Universe became Crown Zenith, Shiny Treasure ex became Paldean Fates, Terastal Festival ex became Prismatic Evolutions — all three sold in English as special sets, in Elite Trainer Boxes, tins and collections, with no booster box at all. Mega Dream ex became Ascended Heroes in January 2026. If you want a sealed box of one of these sets, the Japanese High Class box is the one that exists — see the Japanese vs English guide for how the two prints compare.

Questions

Good to know

What is a High Class pack?

High Class is an official Japanese product category, not a fixed card count. VSTAR Universe, Shiny Treasure ex, Terastal Festival ex and Mega Dream ex have 10 cards per pack. The earlier TAG TEAM GX All Stars is also High Class, but its official specification lists 11 cards per pack.

How many cards are in a High Class box?

For the four sets in this guide: 10 packs × 10 cards = 100 cards. The set lists are far larger — 262, 360, 237 and 250 cards for the four sets above — so a box never contains the full set.

Is a Pokémon ex guaranteed in every pack?

The official Shiny Treasure ex and Terastal Festival ex pages advertise guaranteed Pokémon ex. That does not establish an SSR or SAR guarantee per box. Verify the exact set and the unit named in its specification: pack and box guarantees are different. VSTAR Universe is a Sword & Shield-era set of V and VSTAR cards. We do not infer pull rates from these statements.

Which High Class packs exist?

In the vault: VSTAR Universe (December 2022), Shiny Treasure ex (December 2023), Terastal Festival ex (December 2024) and Mega Dream ex (November 2025). Earlier High Class packs, not stocked, include VMAX Climax (December 2021) and Shiny Star V (November 2020).

Is there an English booster box of Crown Zenith or Prismatic Evolutions?

No. Crown Zenith, Paldean Fates and Prismatic Evolutions were released in English as special sets — packs came in Elite Trainer Boxes, tins and collections, not in booster boxes. The Japanese High Class box is the sealed box of those cards.

Is Heat Wave Arena a High Class pack?

No. Heat Wave Arena (SV9a) is an enhanced expansion — 5 cards per pack, 30 packs per box — released between the main sets. High Class is the official product classification; ten cards per pack alone does not define it.
