Trace in Pokémon Brilliant Diamond & Shining Pearl

Copies an eligible opposing Ability on entry.

Copies an eligible adjacent opponent’s Ability, choosing randomly when multiple opponents are eligible, and replaces Trace with it. If no eligible Ability is initially available, it can activate when one becomes available. It cannot copy Forecast, Flower Gift, Imposter, Multitype or Trace; Wonder Guard is not excluded by the modern rule.
