An arena tag
Arena Tag class for Fairy Lock. Fairy Lock prevents all Pokémon (except Ghost types) on the field from switching out or fleeing during their next turn. If a Pokémon that's on the field when Fairy Lock is used goes on to faint later in the same turn, the Pokémon that replaces it will still be unable to switch out in the following turn.
