Metamon Teams

Pokémon Showdown teambuilder files compiled or procedurally generated by the Metamon project.

Figure 1

Teams in these datasets were legal on the Showdown version we were using when they were generated, but may not be legal today. We do release new versions, but cannot keep up with rule changes. You can always edit the rules on your local server to make them legal, but you should be careful to verify teams before deploying to another server.

set_name Teams Per Battle Format Description
"competitive" Varies (< 30) Human-made teams scraped from forum threads. These are usually official "sample teams" designed by experts for beginners, but we are less selective for non-OU tiers. This is the set used for human ladder evaluations in the paper.
"paper_variety" (Gen 1-4 Only) 1k Procedurally generated teams with unrealistic OOD lead-off Pokémon. The paper calls this the "variety set". Movesets were generated by sampling from all-time usage stats.
"paper_replays" 1k (Gen 1-4 OU Only) Predicted teams from replays. The paper calls this the "replay set". Surpassed by the "modern_replays" set below. Used the original prediction strategy of sampling from all-time usage stats.
"modern_replays" 8k-20k
(OU Only)
Predicted teams based on recent replays using the best prediction strategy we have available for each generation. The result is a diverse set representing the recent metagame with blanks filled by a mixture of historical trends.
"modern_replays_v2" Gen1: 19k, Gen2: 13k, Gen3: 31k, Gen4: 27k, Gen9: 158k An updated version of modern_replays that adds teams from Summer 2025 replays.

modern_replays and competitive are the main sets. Strategies for modern_replays creation differ by gen. Generally, they are teams from replays played in the last year filled by the ReplayPredictor, which looks up "more revealed" versions of the team in other replays and picks between them based on usage stats in the months surrounding the battle's date. We use teams from the last ~year, with no minimum ELO rating.

The changelog for versions (revision) is:

  • v0: original paper teams. Gen 1, 2, 3, and 4 OU/NU/UU/Ubers.
  • v1: first version of "modern_replays" set built by filling in the blanks of 2024 replay teams with naive sampling from all-time usage stats
  • v2: improves/expands "modern_replays" with a new team prediction strategy based on looking up similar teams in Metamon's huge replay dataset
  • v3: adds Gen 9 OU competitive teams. Adds first version of Gen 9 OU modern_replays. Regenerates Gen 4 modern_replays to deal with Machamp ban.
  • v4: adds modern_replays_v2. Removes nicknames from competitive/gen9ou.
