• Official Pokémon TCG Japanese Ninja Spinner booster pack art featuring Mega Greninja ex — *Official Ninja Spinner booster pack art*

Quick overview

Ninja Spinner is the Japanese M4 Mega Expansion Pack and is scheduled to release in Japan on March 13, 2026. Official product details list the set at 83 cards before secret rares, with booster packs containing 5 cards at 180 yen each; booster boxes contain 30 packs and are listed at 5,400 yen tax included. Current reporting also indicates that cards from Ninja Spinner will feed into the English set Chaos Rising in May.

Why Ninja Spinner matters

This set is the current spotlight release for players and collectors following the Mega Evolution era because it puts Mega Greninja ex front and center while also expanding multiple archetypes at once. The previews so far show support for Water, Psychic, Metal, Darkness, and niche evolution strategies, making the set relevant both for sealed collectors and competitive players who track new engines early.

Mega Evolution cards revealed

The cards below are some of the most important or most discussed reveals currently published. They are a good mix for a WordPress post because they combine chase appeal, competitive interest, and visual variety.

Mega Greninja ex is a Stage 2 Pokémon that evolves from Frogadier. Its Mortal Shuriken Ability lets you discard 1 Basic Water Energy from your hand while it is in the Active Spot to place 6 damage counters on 1 of your opponent’s Pokémon. Its attack, Ninja Spinner, costs [W][W] and deals 120+ damage. You may return 1 Water Energy attached to Mega Greninja ex to your hand to increase the attack by 80 more damage.

As a Mega Evolution Pokémon ex, if it is Knocked Out, your opponent takes 3 Prize cards. It has Lightning Weakness, no Resistance, and a Retreat Cost of 1.

Mega Floette ex is a Stage 1 Psychic-type Pokémon that evolves from Floette. Its first attack, Gentle Light, costs [P] and heals 30 damage from each player’s Pokémon. Its main attack, Eternity Bloom, costs [P][P][P] and deals 200 damage, while also letting you search your deck for up to 4 Basic Psychic Energy cards and attach them to your Benched Pokémon in any way you like before shuffling your deck.

As a Mega Evolution Pokémon ex, if it is Knocked Out, your opponent takes 3 Prize cards. It has Metal Weakness, no Resistance, and a Retreat Cost of 1.

Mega Dragalge ex is a Stage 1 Pokémon that evolves from Skrelp. Its first attack, Corrosive Fluid, costs [C][C] and discards all Pokémon Tools and all Special Energy attached to your opponent’s Pokémon, giving it strong disruption potential. Its second attack, Deadly Poison, costs [D][D] and leaves your opponent’s Active Pokémon Poisoned, but with a brutal twist: that Poison places 16 damage counters during Pokémon Checkup instead of 1.

As a Mega Evolution Pokémon ex, if it is Knocked Out, your opponent takes 3 Prize cards. It has no listed Resistance and a Retreat Cost of 2.

Mega Pyroar ex is a Stage 1 Fire-type Pokémon that evolves from Litleo. Its first attack, Roaring Mane, costs [R][C] and deals 80 damage, while also reducing the damage done by the Defending Pokémon’s attacks by 50 during your opponent’s next turn. Its second attack, Big Bang Fire, costs [R][R][C] and starts at 290 damage, but it does 10 less damage for each damage counter on Mega Pyroar ex.

As a Mega Evolution Pokémon ex, if it is Knocked Out, your opponent takes 3 Prize cards. It has Water Weakness, no Resistance, and a Retreat Cost of 2.

A Mega Greninja ex set with real gameplay potential

Ninja Spinner does not look like a filler release. The official reveal makes Mega Greninja ex the face of the set, and the supporting cards around it show a clear design plan: efficient setup, reusable Water resources, and pressure from both direct damage and board control. Mega Greninja ex can place six damage counters with its Ability and then threaten a boosted Ninja Spinner attack by bouncing a Water Energy back to hand. That combination gives the card both tempo and flexibility, which is exactly the kind of design that gets players talking as soon as previews start rolling in.

The set is broader than just Water support

What makes Ninja Spinner more exciting than a single-cover-card release is how much else is packed around the central Water theme. The Delphox line brings hand-refresh utility with Flare Magic, the Chesnaught line adds a punishing reactive tank option, and Mega Floette ex introduces a very different Psychic-based build-around strategy. The current reveal pool suggests that the set is trying to give multiple archetypes a reason to test new shells rather than forcing everyone into one obvious deck.

Mega Floette ex could become one of the set’s sleeper chase cards

While Mega Greninja ex is the obvious headliner, Mega Floette ex may end up being one of the most talked-about collector and player cards from Ninja Spinner. Eternity Bloom hits for 200 and accelerates up to four Basic Psychic Energy to your Bench, which is already attractive. On top of that, Ange Floette gives each Mega Floette ex in play +150 HP, making the card memorable from both a gameplay and marketing perspective. Cards with unusual HP scaling and dramatic support pieces tend to perform well in preview-season content because they instantly feel different.

Other reveals add depth for collectors and deck builders

Beedrill ex gives the set a clean evolution-based attacker for Grass fans, while Crobat looks like one of the more interesting utility pieces revealed so far because Night Shift can manipulate your next draw by searching the deck and stacking the top card. Sudowoodo and Tomes of Transformation also stand out because they hint at a more experimental mechanic that could make Ninja Spinner memorable even beyond its Mega cards. Add in the four Deoxys formes, Cobalion ex’s Metal energy movement, and support options like Philippe, Bubble Water Energy, and Big Catch Net, and the set starts to look much deeper than the pack art alone suggests.

What collectors should watch before release day

For collectors, the biggest thing to monitor now is how the secret rare lineup fills out once the full set is visible. The main set count is already known, but the art rare, super rare, and higher-rarity cards will likely decide which singles become early chase targets. Mega Greninja ex is the safest early bet for demand, but Mega Floette ex, Crobat, and any premium treatment of the Deoxys formes could also become standout pickups depending on artwork quality and pull rates.

Final verdict

If the current reveals are any indication, Ninja Spinner is shaping up to be one of the more interesting Japanese Pokémon TCG sets of the early 2026 Mega era. It has a flagship card with real star power in Mega Greninja ex, a healthy spread of side archetypes, and enough unusual support cards to keep players and collectors watching each new reveal closely. For stores, bloggers, and sealed-product buyers, it is the kind of set worth covering early because interest is already being driven by both competitive curiosity and collector appeal.
