From Ladder to Worlds: A Regulation M-B Retrospective on the 2026 World Championships

Introduction

Hello everyone,
This is the Showdown Tier team.

Showdown Tier is a web platform dedicated to statistical analysis of the Pokémon metagame.

The 2026 Pokémon World Championships have concluded, with Takuma Yamazaki defeating Hiroshi Onishi 2–1 in the Masters Division final. Before the event, we used two weeks of Pokémon Showdown data to publish a snapshot of the Regulation M-B ladder metagame. Now that usage data, Day 2 advancement figures, and public team sheets are available, we can compare that snapshot with what happened at Worlds.

This is not a simple scorecard of correct and incorrect predictions. The ladder sample covered 158,276 games played from August 13 to August 27, while Worlds was a prepared, open-team-sheet tournament played in best-of-three sets. The more useful question is how well the broad ladder trends anticipated the tournament field—and what became visible only when players prepared for a specific event.

Sources and Scope

This review focuses on the Masters Division and uses data available on August 31, 2026. The tournament had 395 competitors, of whom 57 advanced to Day 2, an overall advancement rate of 14.4%. Day 1 comprised rounds 1–8; Day 2 comprised rounds 9–11, followed by Top Cut.

• Official Worlds standings and coverage for the event structure, bracket, and final result.
• VGC History's public team-sheet aggregation for Masters field usage across all 395 teams.
• Reportworm's community-maintained usage page for Day 2 and Top Cut counts.
• Limitless VGC standings, Top Cut Explorer, and RK9 public team sheets for placements and team composition.

Reportworm notes that its standings and statistics are calculated outside the official tournament software. For a few Pokémon, the number of available team lists differs by one between Reportworm and the complete-field aggregation, so the Day 2 conversion percentages below use Reportworm's own denominators. Conversion also measures how often teams containing a Pokémon advanced; it does not isolate that Pokémon's contribution to the result.

Several teams registered two Pokémon holding Mega Stones as alternative options. We use Mega Evolution names below to identify Pokémon registered with the corresponding Mega Stones, but each player can Mega Evolve only one Pokémon per battle.

The Ladder Read and the Worlds Results

Ladder rows use the species labels in our pre-Worlds report. Worlds field usage is form-specific for the listed Mega Evolutions. "Advanced / registered" is the share of Reportworm's available team lists containing that Pokémon that advanced from Day 1 to Day 2; "Top Cut teams / 13" is representation among the 13 Top Cut teams, not a conversion rate.

A More Centralized Tournament Field

The central read was broadly correct: Kingambit and Basculegion were not just strong ladder performers, but two of the defining pieces at Worlds. Both ranked among the five most common Pokémon in the Masters field, converted to Day 2 at rates above the 14.4% field average, and appeared on the World Champion's team.

Worlds was nevertheless more centralized than the ladder snapshot suggested. Our pre-Worlds report had no Tier S Pokémon under Showdown Tier's usage-and-win-rate criteria, which suggested that the sampled ladder was not severely centralized. That model-specific result still describes the ladder data, but it should not be read as a prediction that a prepared tournament field would be evenly distributed. Kingambit appeared on 12 of the 13 Top Cut teams, suggesting that the upper end of the Worlds field was more concentrated around it than the ladder sample was.

The ladder also understated the prominence of Mega Charizard Y and Mega Floette. They ranked second and sixth in Masters field usage, respectively, making them substantially more common at Worlds than in our ladder sample. Their Day 2 conversion rates were close to the field average, however. High registration and average conversion can coexist when a popular structure occupies a large part of both the advancing and non-advancing field.

How the Two Pre-Worlds Families Performed

Several members of the second family we highlighted—Farigiraf + Mega Raichu Y + Sylveon + Mega Staraptor + Hisuian Arcanine (+ Kingambit)—posted above-average conversion rates. Mega Raichu Y advanced on 10 of 40 teams (25.0%), Mega Staraptor on 15 of 65 (23.1%), Sylveon on 20 of 98 (20.4%), and Hisuian Arcanine on 8 of 31 (25.8%). Each figure was comfortably above the overall 14.4% advancement rate.

These results do not establish that each Pokémon independently caused the higher conversion, especially because they frequently appeared together. They do show that the high-rating ladder core was tournament-viable and that the strong results of several of its members were not limited to the Showdown sample.

Thirteen players finished the Swiss rounds at 9–2 or better and entered Top Cut. The complete public team sheets show that both pre-Worlds families reached that stage, although the Mega Charizard Y family was more prevalent.

• Hiroshi Onishi's runner-up team was the exact six-Pokémon structure highlighted in our article—the “Big Six” of Mega Charizard Y, Mega Floette, Kingambit, Basculegion, Garchomp, and Whimsicott.
• Giovanni Piscitelli and Shohei Kimura also made Top Cut with the same six, giving the exact structure three Top Cut appearances.
• Carson St. Denis used a five-of-six variant that replaced Mega Floette with Sneasler.
• Cary D'Ortona made Top Cut with the exact second family: Mega Staraptor, Mega Raichu Y, Farigiraf, Hisuian Arcanine, Sylveon, and Kingambit.
• Navjit Joshi used a five-of-six version of that family, replacing Farigiraf with Whimsicott.

Takuma Yamazaki's winning team combined an established core with a major innovation. It retained Kingambit, Basculegion, Garchomp, and Mega Floette from the Mega Charizard Y family, but completed the team with Sneasler and Mega Dragonite. That version defeated the exact “Big Six” structure in the final.

Tournament-Specific Innovations

Mega Dragonite was the clearest blind spot. Only nine of 395 Masters team sheets included it, a 2.3% field usage rate. Two of those teams advanced to Day 2, both reached Top Cut, and one won the World Championship. With such a small sample, that run should not be turned into a general claim that Mega Dragonite was the format's best Mega Evolution. It is instead a strong example of how a tournament-specific refinement can be strategically important while remaining almost invisible in broad ladder statistics.

The other major omission was the paired Mega Froslass and Mega Scovillain offense used by Zachary Weed and João Felipe Leite. Their matching teams—completed by Sneasler, Dusk Lycanroc, Basculegion, and Kingambit—both reached the semifinals. The ladder article captured the Kingambit and Basculegion foundation, but not this specific double-Mega core.

How the Low-Usage Watchlist Fared

The pre-Worlds watchlist produced mixed results, which is what we should expect from exploratory ladder signals.

• Hisuian Arcanine received the clearest tournament support: 8 of 31 teams advanced to Day 2, and two reached Top Cut.
• Mega Delphox grew to 11.6% field usage, but only 5 of 46 teams advanced and none reached Top Cut.
• Vivillon appeared on seven teams, Kommo-o on 11, and Mega Mawile on five. None advanced to Day 2.

Those outcomes do not prove that the latter Pokémon are unviable, but their promising ladder win rates were not supported to the same extent by this tournament's results. In retrospect, Hisuian Arcanine provided the strongest tournament evidence in the group, while the others remained speculative options.

Closing Thoughts

Overall, the ladder data gave us a useful outline rather than a complete forecast. It identified Kingambit and Basculegion as central pieces and captured both major team families, but Worlds placed even more emphasis on Kingambit and rewarded innovations such as Mega Dragonite and the Mega Froslass + Mega Scovillain core that were difficult to see in broad ladder statistics.

The comparison also shows why usage, win rate, advancement rate, and Top Cut representation answer different questions. Taken together, the results show how a prepared best-of-three field can refine, concentrate, and occasionally overturn the patterns visible on the ladder.
