Blue Sky Stream & Skyscraping Perfection English Equivalent: Evolving Skies (2021)
By Dexhaul Team · October 12, 2026 · 5 min read
Blue Sky Stream (S7R) and Skyscraping Perfection (S7D), both released July 9, 2021 in Japan, are the two source sets behind Evolving Skies (SWSH07). Evolving Skies landed in English on August 27, 2021 and absorbed roughly 60% of the combined S7R and S7D card pool. The remaining third went to Fusion Strike (SWSH08), released November 12, 2021.
The split matters before you buy. A Dragon-type card from S7D might be in Evolving Skies or in Fusion Strike, and the two English sets are not interchangeable for hunting a specific card.
One more thing to know upfront: the Eeveelution cards in Evolving Skies did not come from S7R or S7D at all. They originated in Eevee Heroes (S6a), a separate Japanese set released June 4, 2021. S7R and S7D cover only the Dragon-type half of Evolving Skies.

What S7R and S7D each contain
S7R (Blue Sky Stream) focuses on sky and flying Dragon-type Pokémon. Its headline card is Rayquaza VMAX, which also appears as a high-rarity alternate-art version. The set leans heavily on Rayquaza, Dragonite, and Flygon lines.
S7D (Skyscraping Perfection) covers a different slice of the Sword and Shield Dragon roster. Dracozolt VMAX and Dracovish VMAX are the featured V cards. Noivern and Dragapult round out the Dragon representation alongside several Trainer cards that eventually spread across both Evolving Skies and Fusion Strike in English.
Both sets share the standard Japanese Sword and Shield era box format: 30 packs, 5 cards per pack. That is 150 cards per box, compared to 360 cards (36 packs × 10 cards) in an English Evolving Skies booster box. The smaller Japanese card pool per box means a higher hit rate on featured VMAX cards when you are specifically chasing S7R or S7D content.

The Eeveelution V and VMAX cards in Evolving Skies (Umbreon VMAX, Espeon VMAX, Glaceon VMAX, Vaporeon VMAX) come from Eevee Heroes (S6a), not from S7R or S7D. See the Eevee Heroes import guide for that half of the set.
Japanese or English: which should you buy?
Chasing Rayquaza VMAX
Rayquaza VMAX is exclusive to S7R and its Evolving Skies prints. If the alternate-art version is your target, you have two paths: S7R booster boxes (smaller pool, higher hit density per box) or Evolving Skies booster packs (larger English pool, wider availability). Individual single cards from both are available separately and skip the pack-opening gamble entirely.
Tournament play
Japanese S7R and S7D cards are not legal for official Pokémon TCG tournament play outside Japan. Both Evolving Skies and Fusion Strike are now in the Expanded format; verify current rotation at pokemon.com.
Collector value and grading
Japanese cards from this era are printed with tighter tolerances than their English counterparts, which can translate to cleaner centering and fewer surface defects. PSA and BGS grade Japanese cards on the same scale as English. If grading is your goal, the smaller Japanese pool also means a pristine S7R Rayquaza VMAX from a sealed box is competing in a thinner secondary market than the English version.
Frequently asked questions
What is the English equivalent of Blue Sky Stream (S7R)?
The primary English equivalent is Evolving Skies (SWSH07), released August 27, 2021. Roughly 60% of the combined S7R and S7D card pool landed in Evolving Skies. The remaining third was distributed into Fusion Strike (SWSH08), released November 12, 2021.
What is the English equivalent of Skyscraping Perfection (S7D)?
Same answer as S7R: Evolving Skies is the primary English counterpart, with a portion going to Fusion Strike. S7R and S7D released on the same day in Japan and both fed into the same two English sets. Verify specific cards on Limitless TCG (S7D).
Does Evolving Skies contain all the S7R and S7D cards?
No. About 30% of the combined card pool ended up in Fusion Strike instead. Trainer cards and some non-featured Pokémon are the most common items that split away. If you are hunting a specific S7R or S7D card and cannot find it in Evolving Skies, check Fusion Strike next.
Where do the Eeveelutions in Evolving Skies come from?
Not from S7R or S7D. The Eeveelution V and VMAX cards (Umbreon VMAX, Espeon VMAX, Glaceon VMAX, Vaporeon VMAX) originated in Eevee Heroes (S6a), a separate Japanese set released June 4, 2021. Buying S7R or S7D hoping to find Umbreon VMAX is a common mistake; those are Eevee Heroes cards.
When did Blue Sky Stream and Skyscraping Perfection release in Japan?
Both released July 9, 2021, according to Bulbapedia. The English Evolving Skies followed seven weeks later on August 27, 2021, one of the shortest JP-to-EN turnaround times of the Sword and Shield era.
Are S7R and S7D cards legal in competitive play?
Japanese cards are not legal for official Pokémon TCG tournament play outside Japan. The English equivalents in Evolving Skies and Fusion Strike are both currently in the Expanded format. Check current rotation at pokemon.com.
