What’s New in M4
Mega Greninja ex headlines the set with a 280-damage Ninja Spinner attack and the Lethal Shuriken ability, which places 9 damage counters before it attacks. Two trainer supporters — Roxie and AZ — get Special Art Rares, alongside four Mega Evolution Pokemon ex cards spread across the set’s rarity tiers.
On the competitive side, Big Catch Net (search your deck for any Basic Pokemon) and Bubble Water Energy (prevents retreat-cost increases) are the two cards drawing the most early deck-building attention in the MEGA format.
Every one of these cards — base rarity through secret rare — is catalogued with its card number on the full M4 Ninja Spinner card list.
Ninja Spinner Chase Cards: The Rarity Hierarchy
The chase cards fall into five rarity tiers — MUR, SAR, SR, AR, and RR — and value drops sharply at each step down. The full list of every card is on the M4 Ninja Spinner card list page.
The MUR Tier: One Card, Set-Defining Value
There is exactly one Mega Ultra Rare in Ninja Spinner, and it’s the card the whole set is built around.
Greninja won Pokemon of the Year in 2020 with over 140,000 votes, and this is its first Mega Evolution card. The MUR features a full-art illustration with premium texture, and at an estimated 1-in-50 boxes (roughly 2%), buying the single is the realistic path to owning one for most collectors.
The SAR Tier: Six Cards, the Realistic Chase
Six Special Art Rares make up the tier collectors are actually pulling for. At an estimated 33% SAR rate per box and six variants in the pool, each individual SAR lands at roughly a 5.5% per-box chance — meaning the Greninja SAR specifically shows up in about 1-in-18 boxes.
| Card | Rarity | Price (¥) | Price (USD) |
|---|---|---|---|
| Mega Greninja ex | SAR | ¥40,429 | ~$263 |
| Cinccino ex | SAR | ¥3,803 | ~$25 |
| Mega Floette ex | SAR | ¥3,246 | ~$21 |
| Roxie’s Performance | SAR | ¥3,143 | ~$20 |
| Mega Dragalge ex | SAR | ¥3,133 | ~$20 |
| AZ’s Tranquility | SAR | ¥1,584 | ~$10 |
The gap between the Greninja SAR and the rest of the tier tells the story of this set — Ninja Spinner is a Greninja-driven release, and everything else is a secondary chase. Cinccino ex SAR is the standout of the non-Greninja cards, while AZ’s Tranquility was the most affordable SAR in the set.
The SR Tier and the Guaranteed Slots
Below the SAR tier, 18 Super Rares round out the set’s mid-value cards. Mega Greninja ex SR (¥3,404) offers the Mega Greninja artwork at a fraction of the SAR/MUR price for players who want the card without the chase. Special Red Card SR (¥1,407) and Mathieu SR (¥1,220) are both seeing competitive play.
Every box also guarantees 4 RRs (Double Rares) and 3 ARs (Art Rares) — these aren’t the chase cards, but they fill out the card list and include the set’s playable staples. The complete rarity-by-rarity list, with every RR and AR included, is on the Ninja Spinner card list page. For Japanese card lists across other sets, our general card list index covers the rest of the MEGA series and beyond.
Pull Rates: How Hard Is It to Pull a Chase Card?
Every Ninja Spinner box guarantees 4 RRs, 3 ARs, and 1 SR-or-better card. The pull-rate figures are estimates from Japanese community tracking of 1,000+ box openings and are not officially confirmed by The Pokemon Company.
| Rarity | Per Box | Chance | Notes |
|---|---|---|---|
| RR (Double Rare) | 4 | Guaranteed | 4 per box, every box |
| AR (Art Rare) | 3 | Guaranteed | 3 per box, every box |
| SR (Super Rare) | ~0.77 | ~65% of boxes | Fills the high-rarity slot when no SAR/MUR |
| SAR (Special Art Rare) | ~0.33 | ~33% of boxes | 1-in-3 boxes across 6 variants |
| MUR (Mega Ultra Rare) | ~0.02 | ~2% of boxes | 1-in-50 boxes, estimated |
How to Buy Ninja Spinner Cards
There are three practical ways into this set, and which one makes sense depends on whether you’re chasing, collecting, or playing.
Buy the Booster Box (For Chasing)
The Sealed booster box is currently listed at ¥10,246 (~$67). Opening boxes is the way to go if you want a shot at the SAR or MUR alongside a full spread of the set’s guaranteed cards, with an estimated 33% SAR rate per box. See also our Ninja Spinner booster box buying guide.
Buy Singles (For Guaranteed Cards)
If you know exactly which card you want — whether that’s a specific SAR from the card list or a playable staple like Big Catch Net — buying the single skips the box odds entirely.
Buy Graded (For a Confirmed Condition Card)
Raw singles carry condition risk; a graded card removes it. The PSA10 MEGA Dragalge ex SAR (M4 116/083) is offered as a PSA 10 back order at ¥7,100 (~$46) — sourced to order; the product page shows the current terms. For a broader look at how PSA grading applies to MEGA-series Pokemon cards, see our PSA10 MEGA Pokemon cards guide.
Price Trends: Will Mega Greninja ex Keep Climbing?
Mega Greninja ex MUR opened above ¥100,000 in its first days on the market and settled to roughly ¥94,223 as supply increased — a 5–6% correction that’s typical for high-demand MURs shortly after release. The SAR has been more stable by comparison, trading in a ¥38,000–¥42,000 range since launch, while the trainer SARs (Roxie, AZ) saw larger 20–30% swings before settling.
Looking at how past MEGA series chase cards have moved after their own initial settlement period gives some context for what might come next, though none of it is a guarantee:
| Set | Top Card | Launch Price | Later Price | Change |
|---|---|---|---|---|
| Inferno X (M3) | Mega Charizard X MUR | ¥100,000 | ¥138,000 | +38% |
| MEGA Dream ex (M2A) | Mega Gengar MUR | ¥95,000 | ¥89,000 | -6% |
| Mega Brave (M1L) | Mega Lucario MUR | ¥80,000 | ¥72,000 | -10% |
The pattern that emerges: character-driven MURs with the broadest global fanbases — Charizard being the clearest example — have appreciated after launch, while others have tended to settle below their opening price. Whether Mega Greninja ex follows the Charizard trajectory or the more common cooling pattern depends on sustained demand outside Japan, which only continued market tracking can confirm.
Three factors are generally cited behind Greninja’s premium: its Pokemon of the Year 2020 win with over 140,000 votes, its status as the first Mega Greninja card printed, and a ninja aesthetic that resonates strongly with Western collectors. None of that guarantees future price movement — treat the figures as historical context, not a forecast.
Ninja Spinner vs Other MEGA Series Sets
Here is how Ninja Spinner compares to the two expansions immediately before it:
| Feature | Ninja Spinner (M4) | MEGA Dream ex (M2A) | Inferno X (M3) |
|---|---|---|---|
| Type | Expansion Pack | High Class Pack | Expansion Pack |
| Top Card Value | ¥94,223 (MUR) | ¥89,000 (MUR) | ¥138,000 (MUR) |
| SAR Rate | ~1/3 boxes | ~1/4 boxes | ~1/5 boxes |
| Chase Pokemon | Greninja | Gengar | Charizard |
| Packs/Box | 30 | 10 | 30 |
Ninja Spinner’s estimated ~33% SAR rate is the highest of the three, and its 30-pack expansion-format box gives more total pulls than MEGA Dream ex’s 10-pack High Class format. For collectors weighing box format against chase-card odds rather than chasing a specific Pokemon, that combination is a large part of why Ninja Spinner compares favorably even against sets with a higher-value top card. The card-by-card lists for all three sets are on our card list index.
JPN vs English: Ninja Spinner vs Chaos Rising
The English equivalent of this set, Chaos Rising, released May 22, 2026. Here’s how the two versions compare for buyers deciding which to target.
| Version | Release Date | Pre-release | Set Size |
|---|---|---|---|
| JPN (Ninja Spinner) | March 13, 2026 | — | ~120 cards |
| ENG (Chaos Rising) | May 22, 2026 | May 9–17, 2026 | 120+ cards |
JPN buyers got roughly a 70-day head start on chase cards over the English release. Historically, JPN versions of MEGA series cards have carried a premium over their English counterparts, and that premium tends to vary by rarity:
- MUR cards: 25–40% JPN premium
- SAR cards: 15–30% JPN premium
- SR cards: 10–20% JPN premium
That premium typically peaks in the first few months after the English release and narrows gradually afterward. For anyone specifically deciding between the two versions, our original Ninja Spinner pull rates & best cards report covers the launch-week price data in more depth.

FAQ
Where can I find the full Ninja Spinner card list?
The complete Ninja Spinner (M4) card list, with card numbers and rarities for all roughly 120 cards, is on our M4 Ninja Spinner card list page.
What is the most valuable card in Ninja Spinner?
Mega Greninja ex MUR is the most valuable card in the set; it traded at approximately ¥94,223 (~$612) on the Japanese secondary market after the March 13, 2026 release. The Mega Greninja ex SAR is the second most valuable at roughly ¥40,429 (~$263).
What are the actual pull rates for Ninja Spinner?
Based on 1,000+ box community data: 4 RRs and 3 ARs are guaranteed per box, plus 1 SR/SAR/MUR slot. The SAR rate is approximately 33% (1-in-3 boxes), and the MUR rate is approximately 2% (1-in-50 boxes). These are community-tracked estimates, not officially confirmed rates.
How many Special Art Rares (SARs) are in Ninja Spinner?
Ninja Spinner contains 6 Special Art Rare cards: Mega Greninja ex, Cinccino ex, Mega Floette ex, Roxie’s Performance, Mega Dragalge ex, and AZ’s Tranquility. Each box has an estimated 33% chance of containing one SAR.
Should I buy a box, a single, or a graded card?
Boxes make sense if you want a shot at the SAR or MUR alongside a full spread of guaranteed cards. Singles make sense if you know exactly which card you want. Graded cards remove condition risk entirely for collectors who want a confirmed-grade card without opening variance.
When did Ninja Spinner release in English?
The English equivalent, Chaos Rising, released May 22, 2026, with pre-release events from May 9–17. It carries Mega Greninja ex and other cards adapted from Ninja Spinner alongside cards from other Japanese sets.
Is a Ninja Spinner box worth buying?
The estimated 33% SAR pull rate gives reasonable odds at one of the six Special Art Rares. For Greninja collectors specifically, it’s a strong set to open; for guaranteed value, buying the SAR or MUR as a single locks in the card without the variance.
Are JPN Ninja Spinner cards worth more than English Chaos Rising cards?
Historically yes. JPN MEGA series cards have carried premiums of roughly 25–40% (MUR), 15–30% (SAR), and 10–20% (SR) over their English counterparts, with the premium typically peaking in the first few months after the English release before narrowing.
