Methodology
This page explains how Champions VGC Lab collects, processes and presents competitive Pokémon VGC data. We believe transparency about data sources and methodology is essential for a competitive tool.
Where the data comes from
Champions VGC Lab combines data from several sources. Base Pokémon stats, move data, type matchups and ability descriptions are normalized from community-maintained databases including PokéAPI and Pokémon Showdown's open dex. Competitive context — usage trends, team compositions and format evolution — is informed by editorial analysis of available tournament results, ladder data and regulation announcements. All data is processed server-side during build or import steps; end users never query these sources directly.
How usage rate is calculated
Usage rate is an editorial estimate of how often a Pokémon appears on teams within the modeled metagame. It is informed by observed tournament team sheets, ladder trends and format context. These figures are directional indicators, not exact measurements. They reflect the competitive landscape at the time of the most recent update and should be interpreted as trends rather than definitive rankings.
How win rate is estimated
Estimated win rate is a directional performance indicator derived from available competitive data and editorial review. It reflects how often a Pokémon tends to perform well across observed matchups. Win rate is heavily dependent on team composition, player skill and specific matchups — it is not a guarantee of results and should be used as one of several factors when evaluating options.
How tier placement works
Tier placement combines estimated usage, competitive impact, role flexibility and observed success in tournament settings. A Pokémon can be placed higher or lower than its usage suggests if its role is uniquely valuable or if its performance in high-stakes matches exceeds its general prevalence. Tiers are reviewed each update cycle and may shift as the metagame evolves.
How matchup scores work
Matchup scores are composite heuristics that evaluate how well a Pokémon or team fares against common threats in the current regulation. They consider type matchup, speed benchmarks, common move sets and defensive profiles. These scores are decision aids, not predictions — they help identify potential weak points and guide team adjustments.
How team score works
Team score is a transparent heuristic that evaluates overall team balance. It considers type coverage, speed control options, defensive synergy, offensive pressure and role distribution. The goal is to highlight potential gaps, not to assign a definitive quality rating. A lower score in one category may indicate an area worth testing rather than a hard flaw.
Limits of the model
All figures on Champions VGC Lab are estimates based on available data at the time of publication. They do not guarantee competitive results and should be combined with personal testing, practice and judgment. The metagame evolves constantly — data that is accurate today may shift with new regulations, discoveries or tournament results. We recommend using this site as a planning tool, not as a substitute for gameplay experience.
Editorial review
All recommendations, analysis and tier placements on Champions VGC Lab are reviewed with competitive judgment. Data is not automatically generated or copied from external sources without context. Each piece of editorial content — whether in guides, Pokémon notes or matchup analysis — is written with the competitive player in mind, grounded in observable trends and practical experience. When data is estimated or incomplete, we state it transparently and explain the basis for the assessment.
How regulations update
Regulation sets are stored as structured data and can be updated without rewriting site code. When a new regulation is announced (M-B, M-C, etc.), the legality list, restricted rules and format context are updated to reflect the new environment. Each update is reviewed editorially before publication. The date of the most recent data update is shown below.
How we monitor VGC updates
Champions VGC Online runs a scheduled news monitor that checks official sources, trusted community outlets and our own internal datasets every 10 minutes. The pipeline detects changes, deduplicates entries, scores relevance and only generates editorial content when a real novelty appears. Official announcements with high relevance can be published automatically; community reports and social signals are held as drafts or ignored. Every generated piece includes source attribution, competitive context and internal links to our tools. We do not copy full articles from external sources. Corrections are applied transparently and outdated items are archived.
Last data update: July 2026 (Regulation Set M-A). · Next scheduled review: next regulation cycle.
