When a Pokémon with Trace enters battle, or at the start of battle, Trace will copy the Ability of its opponent. Trace copies the ability of one of the opponents at random during a Double Battle and/or a Triple Battle.
In the event that Trace isn't able to copy the opponent's Ability due to either having an untraceable Ability or an opponent having Trace, then Trace will copy the next opponent's Ability, either due to the opposing team making a Pokémon substitution or the opposing target was defeated.
Trace doesn't have an effect in the overworld.
