Competitive-level gaming is a very popular hobby, bolstered even further in recent years. Pokémon is no different in this regard; since the release of Scarlet and Violet, participation at tournaments has never been higher. Because of the Pokémon VGC's popularity and long history, there is a multitude of teams, individual Pokémon, and overall strategies for players to pick from. While a handful of specific Pokémon tend to dominate a particular series of tournaments (such as Flutter Mane), it is unlikely for two teams to be identical in all regards.
