If the leading Pokémon holds a Cleanse Tag, the wild Pokémon encounter rate decreases. Is there any item that, when held by a Pokémon, increases the encounter rate? Please note that a White Flute is not what I'm looking for.
Thank you in advance.
If there was such an item, then it would be listed on this page or this page. No item on either page increases encounter rates, so I'm almost certain that such an item doesn't exist.
