Pokémon Counters: Checks & Counter Guides by Format
Browse observed matchup checks from the available Smogon source artifacts. Each page shows its source period and generated date.
The observed rate p is the fraction of relevant encounters where the target was knocked out or switched out. Lists use p − 4d, where d is the standard error. This is a conservative observation, not a guaranteed switch-in or win rate.

The source artifact reports relevant encounter count n, target KO or switch rate p, and standard error d. The interface does not treat p as a win rate or exact KO rate.
Pick a format to browse its full threat list. Open a Pokémon to compare observed matchup checks, ranked by the conservative upstream score. Inline damage calculations are separate set estimates. Data refreshes when Smogon publishes new stats.
Frequently Asked Questions
What are Pokémon counters?
These pages report observed matchup checks from Smogon matchup artifacts. An observation does not prove that a Pokémon can always switch in safely.
How are the check percentages calculated?
n is the number of relevant encounters. p is the fraction where the target was knocked out or switched out. d is the standard error sqrt(p(1-p)/n). Lists rank p minus four d.
How often are the counter lists updated?
Each page displays the imported source period and generated date. Data changes only when crob.at imports a new source artifact.
How do I use the Pokémon counter search?
Search for a Pokémon in available formats. Open a Pokémon to see observations ranked by p minus four standard errors. Damage calculations are separate set estimates.
