Regulations and data
Which formats are covered
VGC Teambuilder covers Pokémon Champions regulations — the doubles formats played on the ladder and at events. Ask your assistant “which formats do you support?” or have it call list_formats: the answer includes each regulation’s dates, team rules, number of legal Mega Evolutions and whether usage statistics are available.
When you do not name a regulation, tools use the newest one that has published usage statistics.
Singles formats and older mainline VGC rulesets are not covered.
What exists for each regulation
- Allowed Pokémon — the regulation’s published eligible list. Team validation depends on it.
- Usage statistics — published monthly by Smogon from Pokémon Showdown ladder battles. A new regulation has none until the first monthly release after it starts.
- Usage history — one snapshot per month the regulation’s ladder was active. Comparing months needs two; momentum needs three.
How current it is
Usage statistics are refreshed monthly, after Smogon publishes. Rankings always come from the most recent month loaded for the regulation; the trend tools show the months by date.
When a regulation ends, its final month stays available, so you can still look back at it.
Known gaps
- Move legality uses Pokémon Showdown’s learnsets across all generations, not Pokémon Champions’ own move lists.
- Some Mega Evolutions introduced in Pokémon Champions are listed with their Mega Stone and ability but without types and stats yet. The tools say so rather than guessing.
- Stat spreads and held-item availability are not validated.
The Tools page lists the limits of each tool.
