Moxie

Moxie is an ability that increases the user's Attack stat by one stage each time it knocks out an opponent's Pokémon. This can lead to a snowball effect where the user becomes increasingly powerful as it defeats more opponents in battle.

If you want to take advantage of Moxie, consider using it on Pokémon that can easily secure knockouts and also have it at the front of your party. The quick succession of battles will help you maximize the Attack boosts from Moxie.
