On July 9, 2021, a single Japanese booster set changed collector expectations for the Sword & Shield era. S7R Blue Sky Stream (蒼空ストリーム) introduced the Rayquaza VMAX Alt Art — a card that now trades at ¥748,000 ($5,305) and single-handedly drives the sealed box price from its original ¥4,950 MSRP to the current ¥210,000 market rate. A 42× appreciation for a 5-year-old set is rare even in the premium Japanese TCG market, and S7R has done it without any lottery exclusivity or artificial scarcity.
This guide covers everything you need to know before buying sealed S7R: the chase cards, pull rates, full box EV math, and the 5-year price trajectory that made Blue Sky Stream one of the most appreciated S-series sets of all time. If you're comparing S7R against Evolving Skies (its English cousin) or trying to decide whether a ¥210,000 box is worth opening, read this first.
S7R Blue Sky Stream: Set Overview
Blue Sky Stream released as one half of a dual expansion alongside S7D Towering Perfection. The two sets shared a release date but featured different Pokémon pools: S7R focused on dragon-type Pokémon headlined by Rayquaza, while S7D focused on other themes. S7R's dragon lineup made it the immediately more popular of the two sets — and Rayquaza VMAX's Alt Art has kept it that way ever since.

S7R vs. English Evolving Skies
Collectors familiar with Evolving Skies (swsh7) should understand that Blue Sky Stream is only a partial source for the English set. Evolving Skies combined cards from multiple Japanese sources — primarily S7R Blue Sky Stream and S7D Towering Perfection, plus some exclusive English additions. The famous Rayquaza VMAX Alt Art and Rayquaza V Alt Art originate from S7R specifically, while cards like Umbreon VMAX Alt Art ("Moonbreon") are from a different Japanese set entirely (S6A Eevee Heroes).
Top Cards in S7R Blue Sky Stream
Rayquaza VMAX Alt Art — The Crown Jewel of the S-Series Era
Rayquaza VMAX
~¥748,000 (~$5,305)
Pull rate: ~1/20 boxes (est.)
The Rayquaza VMAX Alt Art by Anesaki Dynamic is, by many collector measures, the most desirable VMAX card ever produced. The illustration depicts Rayquaza coiled in a dramatic vertical pose against a swirling celestial backdrop — an art style that broke from the standard VMAX template and set the visual benchmark for what "alt art" could mean in competitive TCG illustration.
At ¥748,000 ($5,305) in near-mint condition, this card alone is worth 3.5× the current sealed box price. The English equivalent (swsh7-218 from Evolving Skies) trades at $733 in the US market, but Japanese versions command a significant premium due to collector preferences for original-language cards and the generally higher standards of the Japanese print quality.
Pull rate is estimated at roughly 1 per 20 boxes — meaning you'd need to open approximately 600 packs to average one copy. A single pull recovers the cost of ~3.5 boxes at current prices.
Rayquaza V Alt Art
Rayquaza V
~¥118,000 (~$837)
Pull rate: ~1/16 boxes (est.)
Ryuta Fuse's Rayquaza V Alt Art (card 76/79) is the second-most valuable card in S7R. The illustration shows Rayquaza in a side profile against a sky-gradient background, emphasizing the Pokémon's serpentine grace. At ¥118,000 ($837), this card alone is worth more than most entire Sword & Shield boxes — and it's the second card you're hoping to pull from any S7R box.
The English equivalent (swsh7-194, same Ryuta Fuse artwork) sells for approximately $280 in the US market, confirming the ~3× Japanese premium that applies to the premium S7R cards.
Dragonite V Alt Art
Dragonite V
~¥79,800 (~$566)
Pull rate: ~1/16 boxes (est.)
Atsushi Furusawa's Dragonite V Alt Art (card 74/79) rounds out the trio of iconic S7R alt art V cards. The artwork depicts Dragonite soaring through clouds in a classic flying pose that captures the nostalgic appeal of one of Generation I's most beloved dragons. At ¥79,800 ($566), Dragonite V Alt Art is a strong third-tier value and particularly appealing to collectors building Kanto dragon collections.
Rayquaza VMAX HR (Rainbow)
The Rayquaza VMAX HR (swsh7-217 equivalent, artist: PLANETA Mochizuki) is the traditional rainbow/gold foil version of Rayquaza VMAX. At ¥34,800 ($247), it's significantly more accessible than the Alt Art while still representing a premium collectible. Pull rate is approximately 1 per 5 boxes — making this the most likely "significant value" hit from any S7R box opening.
Sana SR — Japanese Exclusive Trainer
Sana SR (card 77/79) is a Japanese-exclusive character trainer card that appears only in S7R. Sana is a character from the Pokémon XY anime series, and her S7R SR card features a full-art illustration at ¥10,800 ($77). Because she's a Japanese-exclusive character, this SR has strong appeal for anime-focused collectors who value original Japanese lore representations.
Zinnia's Resolve SR
Zinnia's Resolve
~¥6,780 (~$48)
Pull rate: ~1/box (est.)
Zinnia's Resolve SR (card 79/79) is a full-art supporter card featuring Zinnia from Pokémon Omega Ruby/Alpha Sapphire. The card was a competitive staple during the S7R era for its energy-deck-search effect, and the SR version retains strong collector demand at ¥6,780 ($48). Taira Akitsu's illustration captures Zinnia mid-determination, making it one of the more memorable trainer SR cards of the era.
Should You Buy S7R Blue Sky Stream?
For Rayquaza Collectors
S7R is mandatory for serious Rayquaza collectors. The Alt Art VMAX, Alt Art V, and HR Rainbow together represent the most iconic Rayquaza TCG lineup ever printed. At combined singles prices of ¥900,000+ for all three premium variants, building the collection through box opening is mathematically inferior to buying singles — but the box opening experience carries intangible value for dedicated Rayquaza fans.
For Sealed Investors
S7R has demonstrated one of the most reliable appreciation curves in the S-series: a 42× growth from ¥4,950 MSRP to ¥210,000 over 5 years, with consistent upward momentum and no major price crashes. The fundamental driver (Rayquaza VMAX Alt Art collector demand) has not weakened, and sealed supply continues to decline as boxes are opened and graded cards enter PSA slabs. If you're building a sealed S-series portfolio, S7R is a core holding.
For Pack Openers
The EV math is unfavorable (see below). At a ~35% box EV ratio, you're paying ¥210,000 for an expected ~¥74,000 in card value. The variance is extreme: one Rayquaza VMAX Alt Art pull recovers ~3.5x box cost, but most boxes will return far less. Open if you appreciate the lottery dynamic; buy singles if you're targeting specific cards.
For Competitive Players
Blue Sky Stream's competitive cards (Rayquaza VMAX, Inteleon VMAX, Zinnia's Resolve) have rotated out of standard format. There's no competitive reason to buy sealed S7R — buy singles if you need playable copies for expanded or format-specific events.
S7R Pull Rates & Box EV Breakdown
Pull rate estimates are based on community opening data. Official rates are not published.
| Rarity | Cards in Pool | Rate Per Box |
|---|---|---|
| SA Special Art | 4+ (Rayquaza VMAX, Rayquaza V, Dragonite V, Medicham V) | ~0.25 (1/4 boxes) |
| HR Hyper Rare | Multiple VMAX rainbow | ~0.20 (1/5 boxes) |
| UR Ultra Rare | Gold items/energy | ~0.10 (1/10 boxes) |
| SR Super Rare | V cards (SR full art) + Trainers | ~1-2 per box |
| RRR Triple Rare | VMAX regular | ~2 per box |
| RR Double Rare | V regular | ~4 per box |
Box EV Calculation
| Category | Rate/Box | Avg Value | EV |
|---|---|---|---|
| Rayquaza VMAX Alt Art SA | ~0.05 (1/20) | ¥748,000 | ¥37,400 |
| Rayquaza V Alt Art SA | ~0.0625 | ¥118,000 | ¥7,375 |
| Dragonite V Alt Art SA | ~0.0625 | ¥79,800 | ¥4,988 |
| Medicham V SA / other SA | ~0.075 | ¥3,000 | ¥225 |
| Rayquaza VMAX HR | ~0.10 | ¥34,800 | ¥3,480 |
| Other HR / UR | ~0.20 | ¥3,500 | ¥700 |
| SR V + Trainer (Sana, Zinnia, Rayquaza V SR) | ~2 | ¥6,000 avg | ¥12,000 |
| RR + RRR cards | ~6 | ¥800 avg | ¥4,800 |
| Other cards | — | — | ¥1,500 |
| Estimated Total EV | ~¥72,468 | ||
| Market BOX price | ~¥210,000 | ||
| EV / Cost ratio | ~35% | ||
The 35% EV ratio is one of the lowest among S-series sets — and that's because the vast majority of box value is concentrated in a single card (Rayquaza VMAX Alt Art) with an extremely low pull rate. Most box openings will return ~¥20,000-40,000 in cards. A Rayquaza VMAX Alt Art pull changes the math dramatically: a single hit returns ¥748,000 against the ¥210,000 box cost — a 3.5x multiple that makes the entire S7R investment thesis work.
This dynamic is similar to buying a lottery ticket: statistically unfavorable, but with a large enough prize that the rare hits make the practice economically rational in aggregate (for holders of many boxes). For individual collectors buying one or two boxes, the expected outcome is substantially negative.
S7R Price History: 5-Year Trajectory
S7R's price history is among the most remarkable in S-series collecting:
- Jul 2021 (launch): ¥5,500 — near MSRP, widely available at retail
- Jan 2022: ¥8,000 — early collector interest as Alt Art artwork spreads online
- Jul 2022: ¥15,000 — first major price step as sealed supply starts declining
- Jan 2023: ¥30,000 — international collector demand accelerates
- Jul 2023: ¥55,000 — Rayquaza VMAX Alt Art becomes iconic in TCG media
- Jan 2024: ¥90,000 — significant sealed supply depletion
- Jul 2024: ¥135,000 — crossing the ¥100,000 threshold
- Jan 2025: ¥170,000 — approaching current levels
- Apr 2026: ¥210,000 — 42× appreciation from launch
The consistent upward trajectory without meaningful corrections reflects durable fundamentals: Rayquaza VMAX Alt Art has become a TCG canon card, S7R sealed supply keeps declining, and international demand has not weakened. Whether this trajectory continues depends on Rayquaza card values holding their current levels and sealed supply continuing to contract.
Where to Buy S7R Blue Sky Stream
S7R is long out of print. Sealed boxes and individual cards are exclusively secondary market. Given the ¥210,000+ box price and the potential for grading fraud on premium cards, buying from established, authentication-guaranteed sellers is essential.

Frequently Asked Questions
Is S7R Blue Sky Stream the same as English Evolving Skies?
No. Blue Sky Stream (S7R) is one of multiple Japanese sources for English Evolving Skies (swsh7). Evolving Skies combines cards from S7R Blue Sky Stream, S7D Towering Perfection, and some English-exclusive additions. Key cards like Rayquaza VMAX Alt Art originate specifically from S7R, but Umbreon VMAX Alt Art ("Moonbreon") is from a different Japanese set (S6A Eevee Heroes), not S7R.
Why is Rayquaza VMAX Alt Art so expensive?
The Rayquaza VMAX Alt Art by Anesaki Dynamic (¥748,000 / ~$5,305) combines several premium factors: (1) the illustration broke from standard VMAX templates and set a new benchmark for TCG alt art, (2) Rayquaza is one of the most iconic Legendary Pokémon in collector demand, (3) the pull rate of approximately 1 per 20 boxes makes individual supply scarce, and (4) international collector demand has intensified steadily since release. The card has become a canonical "must-have" for serious Pokémon TCG collections.
How many secret rares are in S7R?
S7R Blue Sky Stream has 12 secret rare cards numbered 68-79. This includes 4+ Special Art (SA) V cards: Rayquaza V, Dragonite V, Medicham V, and the VMAX Alt Art, plus SR versions of those V cards and trainer SRs (Sana, Schoolboy, Zinnia's Resolve). The total set is 79 cards: 67 base cards plus 12 secret rares.
Is S7R worth buying in 2026 at ¥210,000?
The EV ratio is approximately 35%, meaning each box averages ¥72,000 in expected card value against the ¥210,000 cost. Most box openings will return far less than the cost. However, buyers with long-term sealed investment horizons continue to acquire S7R because the price has shown consistent upward appreciation (42× from launch) with no major corrections. For pure ROI, buying Rayquaza VMAX Alt Art singles is more efficient. For the opening experience, sealed S7R delivers genuine high-stakes lottery variance.
What is the difference between Rayquaza VMAX Alt Art and HR Rainbow?
Both cards show Rayquaza VMAX with special rarity treatment, but the artwork is completely different. The Alt Art (Anesaki Dynamic, ¥748,000) features a dramatic vertical composition with a unique cosmic illustration — it's the iconic "Moonbreon-tier" card of S7R. The HR Rainbow (PLANETA Mochizuki, ¥34,800) uses the standard VMAX template with rainbow/gold foiling — the traditional high-rarity treatment. The Alt Art commands a 21x price premium because its illustration broke the template.
How has S7R price appreciated since release?
S7R launched at approximately ¥5,500 above the ¥4,950 MSRP in July 2021. Over 5 years, the sealed box has appreciated to ¥210,000 — a 38-42× increase with consistent upward momentum. The appreciation accelerated particularly in 2023-2024 as Rayquaza VMAX Alt Art gained international collector recognition. No major corrections have occurred, making S7R one of the most reliable sealed appreciation stories in S-series history.
