Japanese Terastal Fest ex (SV8a): prices, chase cards and box guide

The short version

Terastal Fest ex, set code SV8a, is the Japanese High Class Pack whose cards went into English Prismatic Evolutions. As of mid-September 2026 a Japanese booster box sells for about $109 on TCGplayer in the US and holds 10 packs of 10 cards. The chase cards are the Special Art Rares (SARs) of Eevee's eight evolutions, led by Umbreon ex #217 at about $414.

The English printings cost far more at the top. English Umbreon ex is about $1,410, and the eight Eeveelution cards cost about $944 as Japanese singles against about $3,571 in English. Pullnomics has no pull rate data for Japanese packs and computes no expected value for Japanese sealed product, so it sticks to prices, the confirmed configuration and what is guaranteed.

What Terastal Fest ex is

The official product page gives the release date as December 6, 2024, the price as 550 yen per pack including tax, and the contents as 10 cards per pack. It promises a Pokémon ex in every pack, says cards are inserted at random, and states no box size. Bulbapedia's set page supplies that: 10 packs per box, and PokeBeach's release coverage prices the box at 5,500 yen. That is a High Class Pack layout. The usual Japanese box is 30 packs of 5 cards, as our Japanese versus English guide explains.

The numbered set is 187 cards with 50 secret cards above it: 12 Super Rares (SR), 33 SARs and 5 gold URs. The site labels the UR tier Ultra Rare, but it is the gold tier that English calls Hyper Rare. There is no Art Rare tier.

The site lists 485 entries, not 237, because of pattern printings. Bulbapedia records that this set introduced a mirror holofoil Poké Ball pattern on certain cards, with a chance of a Master Ball pattern in its place. TCGplayer lists each pattern printing as its own card with the pattern in brackets. Bulbapedia notes that cards other than Pokémon ex and ACE SPEC cards carry no rarity symbol in this set, and TCGplayer files them as Common. That is why 392 entries show as Common here, Master Ball pattern cards included.

Bulbapedia describes the set as largely reprints of cards from 2023 and 2024. Prismatic Evolutions arrived on January 17, 2025, six weeks later, with 180 cards, and by Bulbapedia's account contains mostly cards from Terastal Fest ex plus the Generations Start Decks. The match is close but not one to one. Bulbapedia also lists Traditional Chinese, Korean, Indonesian and Thai releases of this set, so confirm the language from a listing's photos, not its title.

The numbers

These are the live figures from the Terastal Fest ex set page. Each one is what the Japanese printing sells for on TCGplayer in the US, not a price in Japan.

The median entry is worth about 59 cents. Of 485 entries, 28 clear $10 and nine clear $50. One of every listed printing at market costs about $2,025.

The 33 SARs average about $36, about $1,197 in total, or roughly 59 percent of the list. The eight Eeveelution SARs alone hold about $944, close to 47 percent, and Umbreon ex by itself is about 20 percent.

A second pool is less obvious. The 392 entries filed as Common average $1.82, about $710 in total, around 35 percent of the list. That is high for cards with no rarity mark, because the Master Ball pattern printings sit there: Umbreon (Master Ball Pattern) #92 is about $49 and Sylveon (Master Ball Pattern) #68 about $20.

The five gold URs average about $15, most of it Pikachu ex #236 at about $58, since the other four average under $5. The 12 SRs average $1.33. The 35 Double Rares, the regular Pokémon ex cards that can fill the guaranteed slot, average 63 cents, and the eight ACE SPEC cards 25 cents.

Japanese price history on the site begins on September 18, 2026, so the charts are short for now.

Chase cards

The block below lists the eight priciest SV8a cards today.

Umbreon ex #217 at about $414 is the chase by a wide margin. The next four, Sylveon ex #212 at about $143, Leafeon ex #200 at about $83, Glaceon ex #206 at about $71 and Espeon ex #211 at about $66, add up to about $363. Vaporeon ex #205 is about $64, Flareon ex #202 about $53 and Jolteon ex #209 about $50.

Then the oddity: the Master Ball pattern Umbreon, a card with no rarity mark, is priced within about a dollar of the Jolteon ex SAR. Below it, Eevee ex #223 is about $39, Roaring Moon ex #218 about $33 and Ceruledge ex #203 about $19.

An SAR is not valuable by default. Twelve of the 33 are among the set's top 15 cards, and the other 21 average about $6.60.

Japanese versus English prices

Each Japanese SAR below is paired with the English Special Illustration Rare (SIR) of the same card, and the gold UR with the English Hyper Rare. Each line gives the Japanese price first, as of mid-September 2026.

• Umbreon ex: #217 about $414, English #161 about $1,410.
• Sylveon ex: #212 about $143, English #156 about $533.
• Leafeon ex: #200 about $83, English #144 about $334.
• Glaceon ex: #206 about $71, English #150 about $285.
• Espeon ex: #211 about $66, English #155 about $316.
• Vaporeon ex: #205 about $64, English #149 about $290.
• Flareon ex: #202 about $53, English #146 about $206.
• Jolteon ex: #209 about $50, English #153 about $196.
• Roaring Moon ex: #218 about $33, English #162 about $167.
• Pikachu ex, gold: UR #236 about $58, English Hyper Rare #179 about $62.

The eight Eeveelutions cost about $944 in Japanese and about $3,571 in English, roughly 3.8 times as much. Card by card the English price runs from about 3.4 times the Japanese one for Umbreon ex to about 5 times for Roaring Moon ex. The gold Pikachu ex is the exception, with the two printings within about $4 of each other.

That describes two markets. It is not a verdict on either language and not a forecast.

Two things stay out. Eevee ex, because the Japanese set has two SARs under that name against one English SIR, and we could not match the pair with certainty. Pattern cards, because the English data here does not price the Poké Ball and Master Ball printings separately. Our Prismatic Evolutions guide covers the English set.

Sealed product

The booster box is about $108.91, which at 10 packs is about $10.89 per pack. A loose pack is about $10.59, so ten loose packs would cost about $106, about $3 less than the sealed box. An English Prismatic Evolutions pack is about $14.29, also 10 cards, and the English set has no booster box.

What is firmly documented about a box: 10 packs, 100 cards and one Pokémon ex per pack, and nothing more. PokeBeach and PokeGuardian, both hobby news sites, reported around release that a box also holds one SAR, sometimes with an SR or a UR as well, plus three mirror pattern cards, which can all be Poké Ball patterns with no Master Ball. Those are reports, not a promise from The Pokémon Company. Even if they hold, an SAR can be the $414 Umbreon ex or one of the 21 that average about $6.60, and the site has no data on how they are distributed.

This site publishes no EV for an SV8a box. Its expected value for an English Prismatic Evolutions pack rests on English pull rates and prices, and says nothing about an SV8a pack.

An SV8a box may reach you with no shrink wrap. Our resealed product guide cites Screen Rant's March 2025 report that Pokémon Center stores in Japan peel the plastic off boxes at sale. A bare box is therefore not evidence of tampering by itself, though it gives you no outer seal to inspect. The importers' rule of thumb is an intact cardboard tear strip.

How to buy it

Two eBay buttons sit on every SV8a card page and on both sealed product pages. The first runs an eBay search for Buy It Now listings from US sellers with Japanese, JPN or JP in the title, leaves out proxies, lots and other languages, sorts by price plus shipping, and caps the item price at 12 percent under market. The second is the same search without the cap. Both are affiliate links. The block below opens those searches for the SV8a booster box and booster pack, already filtered to Japanese listings under the below-market price.

The cap is on the item price, so add shipping yourself. Below market means a landed price, item plus shipping, at least 12 percent under: about $96 delivered for the box, about $364 for a Near Mint Umbreon ex SAR. When the capped search comes back empty, nothing is listed below market at that moment. Use the second button to see every current price, and eBay's "Save this search" so eBay emails you new matches.

Both searches are limited to US sellers, so there is nothing to import. A box or card ordered from Japan is different: since August 29, 2025 a shipment of any value can carry import charges, so find that line at eBay checkout.

Card prices on the site are for raw Near Mint copies. Under the methodology, a Lightly Played copy is measured against 85 percent of market, so a Lightly Played Umbreon ex SAR must land near $310 to count. eBay's Authenticity Guarantee applies to single cards sold for $200 or more, which at today's prices means Umbreon ex and nothing else in this set. Look for the mark on the listing itself. Boxes and packs are not eligible.

Pattern cards need one more check: the Master Ball pattern Umbreon shares its number, 92, with cheaper printings of the same card, so match the pattern in the photos. Confirm Japanese text and the Japanese back in the photos too. Our guide to spotting fakes has the rest.

Who it suits

SV8a suits a collector who wants the Eeveelution artwork and does not need English text, and pattern collectors, since pattern printings have their own pages and prices here. It also suits anyone who wants a ten pack opening session where every pack holds a Pokémon ex. Budget that as entertainment: this site cannot tell you what a box returns on average.

US tournament players should look elsewhere. Under Play! Pokémon rules the Japanese card back counts as marked, which keeps SV8a cards out of Championship Series events here.

Bottom line

Terastal Fest ex is a 10 pack box at about $109, with a Pokémon ex in every pack and no official guarantee above that. The eight Eeveelution SARs hold close to half of the list's value, led by Umbreon ex at about $414. The same eight cards cost about 3.8 times as much in English today, a fact about two markets and nothing more. To buy one card, find it on the set page or through the Japanese index, then use the eBay buttons on its page. For a box, compare the landed price with about $96, check the tear strip, and open it for fun.
