Released on March 13, 2026, Ninja Spinner (M4) is a thrilling Japanese Pokémon TCG expansion that continues the momentum of the Mega Evolution era. Focusing heavily on speed, stealth, and Water-type strategies, this set brings the incredibly popular Mega Greninja ex to the forefront of the hobby.
With 83 cards in the main set and a massive 37 secret rares to hunt for, Ninja Spinner offers a diverse and incredibly rewarding opening experience. Because Greninja is consistently ranked as one of the most popular Pokémon in the world, booster boxes for this set have seen massive demand. But before you invest in these highly sought-after packs, you need to know exactly what the pull rates look like.
Based on aggregated community data and booster box ratios, here is exactly what to expect.
The Best Chase Cards in Ninja Spinner
Unsurprisingly, the most valuable cards in Ninja Spinner revolve around its flagship Pokémon and some fantastic Supporter artwork.
The absolute crown jewel of the set is the Mega Greninja ex Mega Ultra Rare (MUR). As with previous sets in this era, the stunning gold-plated MUR is the ultimate flex for collectors and by far the hardest card to pull.
If you miss out on the MUR, the Mega Greninja ex Special Art Rare (SAR) is an incredibly strong secondary chase that captures Greninja’s stealthy aesthetic perfectly. Beyond the ninjas, collectors are aggressively hunting for the Supporter SARs, particularly Roxie’s Performance and AZ’s Tranquility, both of which feature gorgeous, vibrant artwork.
Guaranteed Hit Rates in Ninja Spinner Booster Boxes
Because Ninja Spinner is a standard Japanese main expansion, a sealed booster box contains 30 packs (with 5 cards per pack).
If you open a fully sealed, untampered booster box, you are mathematically guaranteed to pull at least the following:
- 1 Super Rare (SR) or better (If you are lucky, this slot upgrades to a Special Art Rare or the elusive Mega Greninja ex MUR!)
- 1 Item-specific Super Rare (A guaranteed Trainer/Item SR slot)
- 3 Art Rares (AR)
- 4-5 Double Rares (RR)
Ninja Spinner Pull Rates Chart
Using those guaranteed booster box ratios, here is the estimated hit rate per individual Ninja Spinner booster pack:
| Card Type | Ratio | Percent Chance |
|---|---|---|
| Double Rare (RR) | ~1:7 | ~14% per pack |
| Art Rare (AR) | 1:10 | 10% |
| Item Super Rare (SR) | 1:30 | 3.3% |
| Pokemon/Supporter SR | 1:39 | ~2.5% |
| Special Art Rare (SAR) | ~1:105 | ~0.9% |
| Mega Ultra Rare (MUR) | ~1:1500 | <0.07% |
(Note: The Mega Ultra Rare is still a generational chase. At a rate of roughly 1 in 50 boxes, you only have about a 2% chance of finding the gold Mega Greninja ex in any given booster box. SARs are much more manageable, appearing in roughly 1 out of every 3.5 boxes.)
Is Ninja Spinner Worth Opening?
Absolutely! Thanks to the massive popularity of Greninja and the inclusion of beautifully illustrated Art Rares (AR) for classic Pokémon, this set is incredibly fun to open.
Because the set also focuses heavily on Water-type strategies, many of the cards hold competitive value for players, driving up the demand for even the standard Double Rares (RR). Whether you are a Greninja superfan, a competitive player, or just love the ninja-themed aesthetic, M4 is a fantastic addition to the Mega Evolution era.
