Rillaboom

Performance Metrics

Rillaboom has a reported usage rate of 38.43% and win rate of 51.21% in VGC 2026 Regulation M-C (Pokemon Champions) (displayed tier: A). The report covers 09/17/2026 to 10/01/2026, with 275,278 recorded battles. 108,360 wins and 103,234 losses (211,594 recorded team appearances). Usage is recorded team appearances divided by twice the report battle count; win rate is wins divided by wins plus losses for teams containing this Pokemon. Neither metric measures individual strength. Small samples can produce extreme percentages.

Usage Trends

Usage was 39.50% in the first available period (09/17~; n=137,642 team slots) and 38.87% in the last available period (09/28~; n=137,642 team slots), a change of -0.63 percentage points. This endpoint comparison does not describe every intervening period or explain the cause; small samples can fluctuate substantially. Periods without sample counts are excluded. Win rate was 51.18% in the first available period (09/17~; n=54,363 recorded appearances) and 51.12% in the last available period (09/28~; n=53,506 recorded appearances), a change of -0.06 percentage points. This endpoint comparison does not describe every intervening period or explain the cause; small samples can fluctuate substantially. Periods without sample counts are excluded.

Rating-band Observations

Across 5 available rating bands, usage ranged from 30.97% (~R1122; n=108,496 team slots) to 44.17% (R1348~; n=110,878 team slots), a spread of 13.20 percentage points. Overall usage was 38.43%. Bands use battle-average ratings, not individual player skill. Missing bands are excluded; differences are descriptive, not evidence of statistical significance.

Recorded Moves

Among the returned moves, Fake Out has the largest recorded battle count (61,205; ties may occur). Move counts refer to distinct battles with a recorded use. The displayed percentage divides that count by this Pokemon's recorded team appearances; these counting units differ when both teams contain it. This is not moveset adoption. Unused moves and missing move records cannot be distinguished here. These data do not establish which move is strongest or underused.

Teammate Observations

In the returned frequent-teammate sample: Incineroar: 51.3% wins in 81,118 recorded pair observations; Sneasler: 50.8% wins in 67,515 recorded pair observations; Gholdengo: 52.5% wins in 59,245 recorded pair observations. These are team-level outcomes with both Pokemon on the roster, not a measurement of synergy. Other teammates, player selection and small samples can affect these percentages.

Opponent-team Observations

Returned higher-win-rate opponent group: Pincurchin: 60.5% wins in 2,709 recorded pair observations; Clefable: 58.8% wins in 2,770 recorded pair observations; Inteleon: 58.1% wins in 2,427 recorded pair observations. Returned lower-win-rate opponent group: Kommo-o: 44.7% wins in 6,125 recorded pair observations; Meowstic-F: 47.7% wins in 2,221 recorded pair observations; Kingambit: 48.0% wins in 38,289 recorded pair observations. Wins refer to the team containing the focal Pokemon when the named Pokemon was on the opposing roster. They are not direct one-on-one results or proof of a counter; sample sizes and other team members matter.

Interpretation Limits

These summaries describe the collected battles within the report period. Team composition, player selection, repeated players and incomplete records can affect results. Differences do not establish causation, statistical significance or a recommended build.
