One of these boxes released on September 16, 2026. The other released in 2021 and is out of print, currently listed at ¥240,000 against a ¥165 pack price. Comparing 30th CELEBRATION (M6a) to S7R Blue Sky Stream is really a comparison between a current-release box you can buy at a reasonable price and a discontinued set that has become a specialist purchase.
30th CELEBRATION (M6a) released worldwide on Wednesday, September 16, 2026. S7R Blue Sky Stream (蒼空ストリーム) released in Japan on July 9, 2021, as one half of a dual-set launch alongside S7D Towering Perfection. Both are Japanese 拡張パック at the pack level, but the market gap between the two on September 18, 2026, is enormous.
The 30th CELEBRATION Booster Box is a current release (MSRP ¥7,200, 20 packs of 6 cards) currently listed at ¥23,500–¥28,500 on our site. S7R Blue Sky Stream (MSRP ¥165 per pack, 5 cards per pack) is an out-of-print 2021 set currently listed at ¥240,000 — a specialist purchase built around the Rayquaza V Super Rare pair, not an entry-level box.

30th CELEBRATION: The Current Release
The official Japanese product page confirms ¥360 (tax included) per pack, six foil cards per pack, and one YOSHIROTTEN-designed Basic Energy guaranteed in every pack. The ¥7,200 box price is official (via Pokemon Center Online listings); the 20-packs-per-box figure is not printed on the official pack page itself but follows from ¥360 × 20 = ¥7,200.
Main-set M6a cards carry regulation mark J and are usable under the Standard regulation that took effect January 23, 2026 (marks H, I and J). The 30 Classic Collection reprints (136–165), including the Charizard above, carry no regulation mark at all; the official page states they cannot be used in the current Standard regulation but can be used wherever the original card they reprint is legal. If you already have the booster box on your list, its same-day companion product is the Premium Deck Set Espeon & Umbreon (update: currently sold out — restock requests via Quick Order), two fixed decks with no packs to open.
Blue Sky Stream: The Out-of-Print Specialist Box
S7R Blue Sky Stream released in Japan on July 9, 2021, as an official Sword & Shield-era expansion pack, sold alongside its companion set S7D Towering Perfection. The official product page confirms ¥165 (tax included) per pack and 5 cards per pack; our buying guide reports 30 packs per box, a figure not printed on the official page. The official card database lists 79 entries for the set: a 67-card base run plus 12 additional numbers (068/067 through 079/067). The database confirms those numbers; it does not print rarity labels.
Per our guide, nine of these numbers carry the SR rarity: two Rayquaza V printings (075/067 and 076/067), two Dragonite V printings (073/067 and 074/067), two Medicham V printings (071/067 and 072/067), and single-print Supporter cards Sana (077/067), School Boy (078/067) and Zinnia’s Resolve (079/067). The database confirms the card numbers; the SR label is our guide’s.
Chase Cards Compared
M6a’s headline chase cards are the two Futuristic Rares by YOSHIROTTEN — Mew ex (135/103) and Mewtwo ex (134/103) — plus the Special Art Rare Pikachu ex pair, day (126/103) and night (127/103). PokeBeach also reports that three secret Mew cards, numbered R/RGB, G/RGB and B/RGB and illustrated by YOSHIROTTEN, were pulled from early-opened 30th CELEBRATION products and surfaced in a Pokemon TCG Live update on September 15, 2026; they sit outside the /103 numbering and every official list, and their pull rate is unknown.
S7R’s chase cards are the two Rayquaza V Super Rares (075/067 and 076/067), with Dragonite V and Medicham V as secondary chases within the same SR tier. Unlike M6a, none of the S7R chases are new — every number has been confirmed for years, and the entire pool sits in a set that is no longer in production.
Which One Fits You
- You want the current 30th anniversary release at an accessible price: the 30th CELEBRATION Booster Box. It is a newly released product currently listed at ¥23,500–¥28,500, with a chance at the set’s new secret rares.
- You specifically collect Rayquaza V or the Blue Sky Stream print run: S7R. This is not a beginner purchase — the box is out of print and currently listed at ¥240,000.
- You want both angles — a modern chase and a vintage-era specialist card: pairing an M6a box with an S7R single (rather than a full box) keeps the specialist spend lower.
