S6K Jet-Black Geist 抽卡概率,最佳卡牌与盒装指南 (2026)

S6K Jet-Black Geist booster box with Shadow Rider Calyrex VMAX Alt Art and Zeraora V Alt Art

On April 23, 2021, Japan received S6K Jet-Black Geist (漆黒のガイスト) — one half of a dual expansion that introduced the Crown Tundra Legendary Pokémon to the TCG. This is the “shadow” half of the release: Shadow Rider Calyrex VMAX as the headline chase card, joined by Zeraora V Alt Art, the famous “Chubby” Blissey V Alt Art, and Caitlin SR. Five years later, sealed boxes trade at ¥30,000 ($213) — a ~6× appreciation from MSRP that positions S6K firmly in the mid-tier of S-series collectability.

This guide covers everything you need before buying sealed S6K: the chase cards, pull rates, EV breakdown, 5-year price history, and how it compares to its sister set S6H Silver Lance.

S6K Jet-Black Geist: Set Overview

S6K and S6H released on the same day as a dual expansion featuring the two Calyrex forms from Pokémon Sword & Shield’s Crown Tundra DLC. S6K got Shadow Rider Calyrex (psychic-type ghostly steed), while S6H got Ice Rider Calyrex (the frozen horseman). Together they represent one of the most thematically ambitious Japanese releases of the S-series, with both Calyrex Pokémon commanding strong collector demand.

S6K vs. English Chilling Reign

S6K Jet-Black Geist is one of two Japanese sources for English Chilling Reign (swsh6). The English set combined S6K (Shadow Rider cards) and S6H (Ice Rider cards) plus some English-exclusive additions. If you’re hunting specifically for Shadow Rider Calyrex, Zeraora V Alt Art, or Blissey V Alt Art (the Chubby one), those originate from S6K Jet-Black Geist specifically — not S6H.

Top Cards in S6K Jet-Black Geist

Shadow Rider Calyrex VMAX Alt Art — The Headline Chase

Shadow Rider Calyrex VMAX Alt Art from S6K Jet-Black Geist — artwork by Mitsuhiro Arita

SA

Shadow Rider Calyrex VMAX

~¥24,800 (~$176)

Pull rate: ~1/20 boxes (est.)

Mitsuhiro Arita — the legendary artist behind the original 1999 Base Set Charizard — delivers one of his most striking modern illustrations with the Shadow Rider Calyrex VMAX Alt Art. The artwork captures the spectral horse mid-charge against a haunting violet-black background, emphasizing the Pokémon’s ghostly nature in a way the standard VMAX template cannot. At ¥24,800 ($176), it’s S6K’s definitive chase card and arguably one of the strongest Arita illustrations of the Sword & Shield era.

Arita’s involvement alone drives significant collector premium. His modern catalog is small compared to his Base Set era work, and cards bearing his signature carry inherent artist value that supplements their rarity pricing.

Zeraora V Alt Art

Zeraora V Alt Art from S6K Jet-Black Geist — artwork by Atsushi Furusawa

SA

Zeraora V

~¥22,000 (~$156)

Pull rate: ~1/16 boxes (est.)

Atsushi Furusawa’s Zeraora V Alt Art is one of the most dynamic V-form illustrations in the S-series. Zeraora is depicted mid-leap with electricity arcing from its paws — a cinematic action pose that captures the mythical lightning Pokémon at its most iconic. At ¥22,000 ($156), it’s the second-most valuable card in S6K and a must-have for Zeraora collectors.

Furusawa is also known for Dragonite V Alt Art from S7R Blue Sky Stream. His style — dynamic action poses with strong lighting — has become recognizable across the S-series era, and Zeraora V Alt Art is widely considered one of his strongest works.

Blissey V Alt Art (“Chubby Blissey”)

Blissey V Alt Art from S6K Jet-Black Geist — the famous Chubby Blissey illustration by Saya Tsuruta

SA

Blissey V

~¥15,000 (~$106)

Pull rate: ~1/16 boxes (est.)

Saya Tsuruta’s Blissey V Alt Art is widely known in collector circles as the “Chubby Blissey” — a charming, plush-like illustration of Blissey that broke from the standard combat-focused V card template. The card depicts Blissey in a gentle, relaxed pose surrounded by soft pastel colors, emphasizing the Pokémon’s caretaker identity over its battle attributes.

At ¥15,000 ($106), Chubby Blissey is a top-tier Alt Art despite Blissey’s relative lack of competitive impact. The card succeeds purely on artistic merit and nickname recognition — the “Chubby Blissey” moniker has become a shorthand in collector discussions, boosting demand organically over time.

Shadow Rider Calyrex V Alt Art

Shadow Rider Calyrex V Alt Art from S6K Jet-Black Geist — artwork by kodama

SA

Shadow Rider Calyrex V

~¥8,500 (~$60)

Pull rate: ~1/16 boxes (est.)

Artist kodama’s Shadow Rider Calyrex V Alt Art is the lower-rarity counterpart to Arita’s VMAX. The illustration shows the spectral steed in a more ethereal pose, with flowing dark mane details that contrast the crisp rider form. At ¥8,500 ($60), it’s an accessible entry into the Shadow Rider alt art lineup and pairs naturally with the VMAX version for collectors building complete Calyrex sets.

Caitlin SR

Caitlin SR (the Unova Elite Four member, card 80/83 in JPN) is one of the most aesthetically celebrated trainer SR cards in the S-series. En Morikura’s illustration gives Caitlin an elegant, dreamy quality that has made it a long-term favorite among character card collectors. At ¥8,500 ($60), it’s priced in line with the lower SA tier — unusual for a trainer SR but justified by En Morikura’s distinct illustration style and Caitlin’s fan appeal.

Should You Buy S6K Jet-Black Geist?

For Character Card Collectors

S6K is strong for character card collectors: Caitlin SR (En Morikura), Agatha SR, and Peonia SR all appear with distinctive artist styles. Combined with the high-quality alt art V/VMAX cards, the set delivers consistent artistic value across multiple pull levels.

For Calyrex Collectors

S6K is mandatory for Shadow Rider Calyrex collectors. The V Alt Art and VMAX Alt Art together form the canonical Shadow Rider collection — both featuring unique illustrations unavailable in any other set. S6H Silver Lance covers the Ice Rider Calyrex variants separately.

For Mitsuhiro Arita Collectors

Shadow Rider Calyrex VMAX Alt Art is one of Arita’s highest-profile modern illustrations. Alongside his Noivern V Alt Art (S7D) and other S-series work, S6K represents a premium entry in the Arita modern catalog. For dedicated Arita collectors, buying this card as a single is more efficient than chasing it through sealed boxes.

For Pack Openers

S6K’s EV ratio (~43%) is slightly better than most S-series sets because the SA pool is tightly clustered — no single card dominates the expected value like Rayquaza VMAX does in S7R. This makes S6K a more “balanced” opening experience: you’re less likely to hit a massive jackpot, but also less likely to feel cheated by an average box.

S6K Pull Rates & Box EV Breakdown

Rarity Cards in Pool Rate Per Box
SA Special Art 5 (Shadow Calyrex VMAX/V, Zeraora V, Blissey V, Celebi V) ~0.25 (1/4 boxes)
HR Hyper Rare VMAX rainbow + trainer HR ~0.20 (1/5 boxes)
UR Ultra Rare Gold items/energy ~0.10 (1/10 boxes)
SR Super Rare V cards (SR) + Trainers (Caitlin, Agatha, Peonia) ~1-2 per box
RRR Triple Rare VMAX regular ~2 per box

Box EV Calculation

Category Rate/Box Avg Value EV
Shadow Rider Calyrex VMAX Alt SA ~0.05 ¥24,800 ¥1,240
Zeraora V Alt SA ~0.05 ¥22,000 ¥1,100
Blissey V Alt SA ~0.05 ¥15,000 ¥750
Other SA (Shadow Calyrex V, Celebi V) ~0.10 ¥7,000 ¥700
HR Rainbow cards ~0.20 ¥2,500 ¥500
UR Gold cards ~0.10 ¥1,800 ¥180
SR cards (Caitlin, V full art, trainers) ~2 ¥2,500 ¥5,000
RR / RRR cards ~6 ¥500 ¥3,000
Other cards ¥1,500
Estimated Total EV ~¥13,970
Market BOX price ~¥30,000
EV / Cost ratio ~47%

S6K’s 47% EV ratio is above average for Sword & Shield sets. The reason: instead of one mega-chase card with low probability, S6K distributes value across multiple mid-tier SA cards (Shadow Rider Calyrex VMAX at ¥24,800, Zeraora V at ¥22,000, Blissey V at ¥15,000). This flatter distribution means boxes are more likely to return something meaningful even without a headline hit — but the upside ceiling is lower than lottery-dominated sets like S7R.

S6K Price History: 5-Year Trajectory

S6K Jet-Black Geist booster box price trend 2021-2026

S6K has shown steady appreciation driven by distributed collector demand across multiple valuable cards:

  • Apr 2021 (launch): ¥5,200 — near MSRP
  • Oct 2021: ¥5,500 — minimal initial movement
  • Apr 2022: ¥7,000 — first meaningful price increase
  • Oct 2022: ¥9,500 — Chubby Blissey recognition spreads
  • Apr 2023: ¥13,000 — international collector demand
  • Oct 2023: ¥17,000
  • Apr 2024: ¥21,000
  • Oct 2024: ¥25,000
  • Apr 2026: ¥30,000 — current

The ~5.8× appreciation from launch reflects S6K’s balanced value proposition. The set has neither exploded (like S7R) nor stagnated (like S7D), tracking consistently with S-series supply contraction and collector demand growth.

Frequently Asked Questions

Is S6K Jet-Black Geist the same as English Chilling Reign?

No. S6K Jet-Black Geist is one of two Japanese sources for English Chilling Reign (swsh6). The English set combined S6K (Shadow Rider Calyrex side) and S6H Silver Lance (Ice Rider Calyrex side) plus some English-exclusive additions. Shadow Rider Calyrex VMAX Alt Art, Zeraora V Alt Art, and Blissey V Alt Art originate from S6K specifically.

Why is Blissey V Alt Art called “Chubby Blissey”?

The nickname comes from Saya Tsuruta’s illustration style, which depicts Blissey in a soft, rounded, plush-like pose that emphasizes the Pokémon’s gentle caretaker identity rather than its battle stats. Collectors coined the “Chubby Blissey” name in English-language forums, and it became the card’s universal identifier. The artistic departure from combat-focused V card templates made it a fan favorite.

What is the top card in S6K Jet-Black Geist?

Shadow Rider Calyrex VMAX Alt Art by Mitsuhiro Arita is the top card at approximately ¥24,800 ($176). Zeraora V Alt Art (~¥22,000) and Blissey V Alt Art “Chubby” (~¥15,000) round out the premium SA tier. Shadow Rider Calyrex V Alt Art and Caitlin SR are both around ¥8,500.

Is S6K worth buying at ¥30,000 in 2026?

S6K has a ~47% box EV ratio — above average for S-series sets. Expected card value per box is approximately ¥14,000 against the ¥30,000 cost. The value is distributed across 3-4 mid-tier SA cards rather than concentrated in one chase, making box openings more consistent. For balanced pack opening or building a Shadow Rider Calyrex collection, S6K is a reasonable purchase. For pure ROI, singles are always cheaper than sealed.

Who illustrated Shadow Rider Calyrex VMAX Alt Art?

Mitsuhiro Arita, the legendary artist who illustrated the original 1999 Base Set Charizard. His modern Pokémon card catalog is small, making any Arita-signed modern card carry inherent collector premium. Shadow Rider Calyrex VMAX Alt Art is considered one of his most dramatic modern illustrations, depicting the spectral horse against a haunting violet-black background.

How does S6K compare to S6H Silver Lance?

S6K (Shadow Rider side) and S6H (Ice Rider side) released on the same day April 23, 2021 with the same ¥4,950 MSRP. S6K has been slightly more popular due to Mitsuhiro Arita’s involvement on Shadow Rider Calyrex VMAX and the viral “Chubby Blissey” nickname for Blissey V Alt Art. Both sets share the same pull rate system and similar box EV math.
