Ninja Spinner is a 30-pack box built around a single card doing all the work: Mega Greninja ex, printed four times on its way up to a gold Mega Ultra Rare. If you’re deciding whether a box is worth opening, most of that decision comes down to how you feel about chasing that one ladder.
This guide covers exactly what’s in a Ninja Spinner (M4) box, where the Mega Greninja ex line sits from Double Rare (RR) to MUR, what a box is currently priced at against its MSRP, and how M4 stacks up against the other MEGA-era Japanese boxes we carry. We ship this set sealed out of Tokyo, so the pricing here reflects what we’ve actually had listed.
Ninja Spinner (M4) released 2026-03-13 with 83 base cards and 120 total including secrets — 12 Art Rare, 18 Secret Rare, 6 Special Art Rare, and 1 Mega Ultra Rare. Mega Greninja ex appears at SR, SAR, and MUR, culminating at MUR 120/083. Box MSRP is ¥5,400 (30 packs × ¥180) — current box pricing is covered below.

What’s Inside a Ninja Spinner Booster Box
Ninja Spinner is a standalone MEGA-era expansion — officially ポケモンカードゲーム MEGA 拡張パック「ニンジャスピナー」 (katakana ニンジャスピナー, not a kanji reading), released in Japan on 2026-03-13. There’s no sister set released alongside it, unlike some other MEGA-era pairs.
Each pack costs ¥180 and contains 5 cards. A box holds 30 packs, which puts box MSRP at ¥5,400 (¥180 × 30 packs).
| Spec | Value |
|---|---|
| Cards per pack | 5 |
| Packs per box | 30 |
| Box MSRP | ¥5,400 (~$37) |
| Base set | 83 cards (001–083) |
| Secret tiers | Art Rare ×12 (084–095), Secret Rare ×18 (096–113), Special Art Rare ×6 (114–119), MUR ×1 (120) |
| Total card count | 120 |
Two quirks stand out in the base 83. Deoxys shows up four times in a row at Uncommon — all four formes (Normal, Attack, Defense, Speed) get a base-set slot, which is unusual density for a single Pokemon’s formes in one set. And the base set carries three Special Energy cards at plain Rare (081–083), sitting right before the Art Rare run starts at 084. Neither is a chase pull, but both are worth knowing if you’re sorting a box by rarity and wondering why Deoxys keeps showing up.
The Art Rare run itself opens with the Kalos starter trio — Chespin (084/083), Fennekin (085/083), and Froakie (086/083) — followed by Froakie’s evolution Frogadier (087/083), before moving through a mixed run of Ampharos, Xerneas, Claydol, Crobat, Metang, Sliggoo, Tauros, and Watchog to close out the AR tier at 095/083.
30 packs × 5 cards works out to 150 cards per sealed box.

The Mega Greninja ex Chase Ladder: RR to MUR
Ninja Spinner has one set flagship, and it appears more times than usual. Mega Greninja ex (メガゲッコウガex) is printed at four separate rarities, climbing from a base Double Rare all the way to the set’s single Mega Ultra Rare:
| No. | Rarity | Slot |
|---|---|---|
| 022/083 | Double Rare (RR) | Base set |
| 098/083 | SR Secret Rare | Secret tier |
| 114/083 | SAR Special Art Rare | Secret tier |
| 120/083 | MUR Mega Ultra Rare | Set flagship, final number |
The official product page leads with Mega Greninja ex and its ひっさつしゅりけん ability (roughly “finishing shuriken”). Each verified set covered here follows this pattern — one Mega ex holds the MUR slot at the very last number of the set — and in Ninja Spinner that card is Mega Greninja ex.
MUR — Mega Ultra Rare — is a rarity tier that debuted with the first MEGA-era sets in 2025. Unlike earlier gold ultra-rare cards, MUR prints carry brand-new illustrations rather than gold recolors of existing full arts, and each verified set covered here has carried exactly one: always its flagship Mega ex, always at the set’s final collection number. Ninja Spinner’s is Mega Greninja ex 120/083; the equivalent slot in Mega Brave, Inferno X, and Abyss Eye belongs to Mega Lucario ex, Mega Charizard X ex, and Mega Darkrai ex respectively. “MUR” itself is press and Japanese-market terminology — the official product pages don’t spell out the rarity ladder by name.
The gap between the SR at the bottom of the ladder and the MUR at the top of it is the entire story of this box — a PSA 10 example of the 098/083 Secret Rare is currently listed at ¥9,167 (~$62) (update: currently sold out — restock requests via Quick Order), while a PSA 10 of the 120/083 MUR was recently listed at ¥175,203 (~$1,192) (update: currently sold out — restock requests via Quick Order) before selling out; restock requests for that card go through our Quick Order page. For a closer look at every printing and how they’ve been priced since release, see our Ninja Spinner pull rates and best cards article.
Other Secret-Rare Chases
Mega Greninja ex isn’t the only line worth knowing before you open a box. Ninja Spinner carries three more Mega ex lines and four non-Mega ex lines into the secret tiers, plus two Supporter cards that get their own SAR treatment.
Cinccino ex (チラチーノex) runs its own secret ladder at SR 103/083 and SAR 117/083 — a PSA 10 of the 117/083 SAR is currently listed at ¥18,540 (~$126) (update: currently sold out — restock requests via Quick Order). Mega Dragalge ex (メガドラミドロex) has its own SR/SAR pair at 102/083 and 116/083; a PSA 10 of the 116/083 SAR is currently listed at ¥12,144 (~$83) (update: currently sold out — restock requests via Quick Order) — priced below the Cinccino ex SAR listing above. Mega Floette ex (メガフラエッテex) and Mega Pyroar ex (メガカエンジシex) round out the Mega ex secrets — Pyroar ex stops at Secret Rare with no SAR.
On the Trainer side, AZ’s Tranquility (AZの安らぎ) and Roxie’s Performance (ホミカの演奏) are the only two Trainer cards in the set that reach Special Art Rare, each printed at Secret Rare (108/083, 110/083) and Special Art Rare (118/083, 119/083). Beedrill ex and Gourgeist ex round out the Secret Rare-only Pokemon lines, and Cobalion ex sits alongside them at SR with no SAR follow-up.
The Secret Rare tier isn’t only Pokemon and Supporters. Four Item cards get the SR treatment — Energy Retrieval, Jumbo Ice, Special Red Card, and Tool Scrapper (104–107/083) — alongside two Stadium cards, Surfing Beach and Prism Tower (112–113/083), and two more Supporters beyond the SAR-tier pair, Philippe and Emma (109/083, 111/083). These Item, Stadium, and Supporter cards fill out the 18-card SR tier alongside the eight secret-rare Pokemon (Beedrill ex, Pyroar ex, Greninja ex, Floette ex, Gourgeist ex, Cobalion ex, Dragalge ex, Cinccino ex).
Current Box Pricing
Official MSRP on a Ninja Spinner box is ¥5,400 (30 packs at ¥180 each). Our sealed boxes, shipped from Tokyo, are currently listed from ¥11,118 (~$76).
| Price point | Amount |
|---|---|
| Official MSRP | ¥5,400 (~$37) |
| Our sealed box, currently listed | From ¥11,118 (~$76) |
That puts our listed box price at roughly double official MSRP. For comparison, a PSA 10 copy of the 120/083 MUR — the top of the Mega Greninja ex ladder covered above — has recently been priced well above the cost of several boxes on its own.
Ninja Spinner vs Abyss Eye: Which Box to Buy
Ninja Spinner sits inside a longer run of MEGA-era Japanese boxes, each one built the same way — a single flagship Mega ex climbing through Double Rare, Secret Rare, Special Art Rare, and finally a lone Mega Ultra Rare at the last number in the set.
| Set | Code | Release | MSRP/pack | Base | Total | MUR card |
|---|---|---|---|---|---|---|
| Mega Brave | M1L | 2025-08-01 | ¥180 | 63 | 92 | Mega Lucario ex 092 |
| Inferno X | M2 | 2025-09-26 | ¥180 | 80 | 116 | Mega Charizard X ex 116 |
| Ninja Spinner | M4 | 2026-03-13 | ¥180 | 83 | 120 | Mega Greninja ex 120 |
| Abyss Eye | M5 | 2026-05-22 | ¥200 | 81 | 118 | Mega Darkrai ex 118 |
An M3 set released between M2 and M4 in the same MEGA-era numbering line, but its details sit outside what this guide covers. Ninja Spinner and its immediate M1L/M2 neighbors all run ¥180/pack and ¥5,400/box MSRP; Abyss Eye is the first set in the line to step up to ¥200/pack.

Pick based on which flagship Mega ex you want a shot at pulling, not on price alone — MSRP only moved by ¥20/pack between Ninja Spinner and Abyss Eye, so the meaningful difference is which chase ladder you’re opening for.
