Tracein Pokémon Polished Crystal

Trace is an ability that allows the Pokémon to copy the ability of an opposing Pokémon when it enters battle. This means that if a Pokémon with Trace faces an opponent with a different ability, it will temporarily gain that ability for the duration of the battle. This can provide strategic advantages, as the Pokémon with Trace can adapt to various situations by utilizing the abilities of its opponents.
