Yuyutei Weekly: Ninja Spinner Set Drops and the Mega Greninja ex Meta Shake-Up — March Week 3
What Japan's largest TCG retailer is talking about this week — and what Singapore collectors should be paying attention to.
The Ninja Spinner expansion has officially landed in Japan, and Yuyutei's content team has been busy dissecting every corner of it. This week's coverage spans two competing set reviews from their in-house writers and a pair of City League tournament reports — all pointing to the same conclusion: Mega Greninja ex (Mega Gekkoga-ex) is the headline card of the new set, and Dragapult ex remains the deck to beat in the current competitive scene.
Here's what went up on Yuyutei this week, and what it means if you're buying, selling, or playing in Singapore.

Ninja Spinner Set Review — Himari Yukikaze's Take
Source: yuyu-tei.jp/show/poc/content/26272
Date: March 13, 2026
Himari Yukikaze published the first major set review for Ninja Spinner, leading with Mega Gekkoga-ex (Mega Greninja ex — Gekkoga is the Japanese name for Greninja) as the standout card of the set.
The flagship card's ability scatters damage counters across the opponent's field, with attacks capable of dealing up to 200 damage. Himari predicts it will dominate early competitive play with the potential to deal up to 320 total damage — enough to counter the widely-played Dragapult ex decks that have controlled the meta.
Other highlights from her analysis:
- Pumpkaboo-ex — Scales damage based on the number of damage counters on opposing Benched Pokemon (multiplied by 50), creating a strong combo potential with Mega Greninja ex's damage spreading.
- Chirachiino-ex (Minccino evolution) — A defensive option with a coin-flip ability to negate incoming attacks; damage output scales with attached energy.
- Crobat — Stage 2 with the "Nightcraft" ability allowing the player to arrange the top card of their deck, offering consistency for setup-heavy builds.
- Prism Tower — New Stadium card; discard 2 cards from hand to draw 1. Niche utility but noted for specific combo interactions.
Cards receiving boosts from the new set: Gekkoga-ex (Fighting Terastall form), Brijurasu-ex, and Namino'ri Beach stadium all gain new synergy value.
Why it matters for Singapore collectors:
- Mega Greninja ex is the flagship chase card of Ninja Spinner — expect it to be the primary price driver for sealed product
- Its competitive viability against Dragapult ex (the dominant deck) gives it genuine play demand on top of collector demand — a combination that historically pushes prices up fast
- Crobat and Pumpkaboo-ex as support picks may see secondary demand from players building Greninja ex variants

Ninja Spinner Set Review — Mossa's Angle
Source: yuyu-tei.jp/show/poc/content/26280
Date: March 17, 2026
Published four days after Himari's review, Mossa takes a more measured look at the competitive implications of the new set — arriving at some of the same conclusions but with a different emphasis.
Mossa focuses on how Ninja Spinner interacts with existing meta staples rather than treating it in isolation. His main points:
- Mega Greninja ex's "Assassination Shuriken" places 6 damage counters on the opponent's Pokemon — particularly devastating against evolution-based decks, where spreading pressure across staged lines is most punishing.
- Special Red Card is flagged as a strong Trainer item: it disrupts the opponent's hand when they are down to 3 or fewer Prize cards, targeting late-game comeback attempts.
- Minccino (the pre-evolution of Chirachiino-ex) avoids being blocked by certain counter-Stadiums, making it a reliable bench option in a Stadium-heavy meta.
- Dragapult ex gets indirectly stronger through new card synergies — Mossa notes that some of the new support tools benefit existing Dragapult ex builds, meaning the format's dominant deck is not weakened by the new set arriving.
- "Book of Change" (dual-effect Trainer card) is Mossa's personal pick as the most interesting new card — its dual condition effect is listed as having strong potential in the right shell, though he stops short of naming an optimal list.
Why it matters for Singapore collectors:
- The Special Red Card is a sleeper pickup — low-profile Trainer items with specific counter applications often fly under the radar at release and spike when a relevant meta shifts
- The confirmation that Dragapult ex gains tools from this set means current Dragapult ex card prices are unlikely to correct downward — existing Dragapult ex singles remain solid holds
- Two Yuyutei writers independently concluding Mega Greninja ex is the set's centrepiece is a strong validation signal for its price direction

Tournament Report: Cynthia's Garchomp ex Goes 5-1 at City League
Source: yuyu-tei.jp/show/poc/content/26250
Date: March 12, 2026
Mossa's tournament report (112) covers his City League run with a Cynthia's Garchomp ex build, finishing 5-1 and falling only to a Bomb-type Dragapult ex deck in the loss column.
The deck runs a 21-Pokemon, 15-Goods, 4-Tool, 12-Supporter, 8-Energy build centred around the Cynthia's Buizel line and supported by Cynthia's Roserade for damage output and Cynthia's Spiritomb for setup.
Match results:
- Win vs Mega Sharpedo ex
- Win vs N's Zoroark ex
- Win vs Mega Lucario ex
- Win vs Mega Raivolts ex
- Win vs Marnie's Hatterene ex
- Loss vs Bomb-type Dragapult ex
Mossa identifies the deck's standout quality as "board formation ease" — the ability to establish multiple Pokemon quickly and stack Cynthia's Roserade copies for compounding damage output. The structure rewards players who can commit to a wide board early and press damage from multiple angles simultaneously.
Why it matters for Singapore collectors:
- Cynthia's Garchomp ex performing at 5-1 in a competitive City League confirms it as a legitimate meta contender — not fringe
- Cards in the Cynthia's support line (Roserade, Spiritomb, Buizel line) gain play demand from this result; worth tracking on the singles market
- This deck did beat N's Zoroark ex and Mega Lucario ex — two commonly discussed picks in the Singapore competitive scene

Tournament Report: Marnie's Oranguru ex — City League Season 3 at 4-2
Source: yuyu-tei.jp/show/poc/content/26240
Date: March 11, 2026
The second tournament report covers Mossa's run with a Marnie's Oranguru ex dark-type build in City League Season 3, going 4-2 (3 wins, 2 losses) before being eliminated in the playoffs.
The deck features 3 copies of Marnie's Oranguru ex as the main attacker, with a supporting cast built around consistency and counter-tech:
- Mareanie (4 copies) — Specifically included to handle Sprigatito's "Restless Pollen" ability, which otherwise disrupts the deck's setup
- Spike Town Gym (4 copies) — Stadium that enables Pokemon deployment without Poke Balls, solving consistency issues in a draw-light build
- Articuno and Froslass — Comeback mechanics for late-game swing turns
- Yveltal and Budew — Tech choices for specific matchup coverage
Match results:
- Win vs Rocket Team variants
- Win vs Cynthia's Garchomp ex
- Loss vs Mega Venusaur ex
- Loss vs Drakloak ex bomb variants
Mossa highlights the deck's core strength as flexibility — it can shift between aggressive and control-oriented lines depending on the matchup. The Dragapult/Drakloak ex bomb variant remains the hard stop.
Why it matters for Singapore collectors:
- Marnie's Oranguru ex finishing 4-2 confirms it as a playable if not tier-1 choice; singles should be accessible at reasonable prices
- Spike Town Gym at 4 copies is a key consistency card that shows up in multiple builds — worth watching as a staple across multiple decks
- The consistent pattern of losses to Drakloak/Dragapult ex bomb variants across multiple reports this week only reinforces Dragapult ex's grip on the format

Japan Market Signals This Week
Three themes stand out across all four Yuyutei pieces this week:
1. Mega Greninja ex is the card to watch from Ninja Spinner.
Two independent set reviews from different Yuyutei writers arrive at the same conclusion. It has competitive viability (not just collector appeal), and it specifically counters the dominant Dragapult ex meta. That dual demand driver — playability plus collector desire — is what pushes a set's flagship card to sustained high prices rather than a brief release spike.
2. Dragapult ex isn't going anywhere.
Every tournament report this week features a loss to some variant of Dragapult ex. The set review notes also confirm Dragapult ex is picking up new tools from Ninja Spinner. If you're holding Dragapult ex cards, the meta signals from Japan this week are not a reason to sell.
3. Cynthia's support line is emerging as a legitimate secondary tier.
The 5-1 Garchomp ex run is hard to dismiss. Cards like Cynthia's Roserade and Cynthia's Spiritomb are likely underpriced relative to where they'll sit if the deck continues to post results.

What to Watch This Week
- Mega Greninja ex (Mega Gekkoga-ex) — Monitor sealed Ninja Spinner product prices on Yahoo Auctions JP and Mercari JP; the flagship card gaining competitive validation typically means sealed product holds better value
- Cynthia's Roserade and Cynthia's Spiritomb — Strong 5-1 tournament result; both cards may see price movement as the deck gets more reps in JP City League
- Special Red Card (Trainer) — Low-profile at release; Mossa flagging it specifically is worth noting — sleeper Trainer pickups often move quietly before breaking out
- Spike Town Gym — Showing up as a 4-of in multiple independent builds; consistent cross-deck play demand makes this a solid pickup before it registers on the wider market
- Dragapult ex singles — Hold signal remains firm; every piece of content this week reinforces its meta dominance
