Flinching prevents a Pokémon from taking its action for that turn, but it only matters if the flinching effect happens before the target moves. Fast Pokémon, priority effects, and certain abilities or items can make flinch strategies more likely. Flinch is usually temporary and does not persist like a major status condition. It can be useful for stealing a turn, stopping setup, or creating pressure, but relying on repeated flinches is inconsistent unless the game provides a specific reliable combination. Some abilities or conditions prevent flinching. Always consider accuracy and speed before planning around a flinch move.
