Is there an item or move that allows Clefairy to gain XP when other Pokémon win?

Question

I've been watching a YouTuber called Chuggaaconroy, and whenever he battles with one of his Pokemon and wins in Platinum, his Clefairy also gains the same amount of XP. He never explained what he did for his Clefairy so I'm wondering if anybody here knows. Thanks!

Not a complete answer, but EXP share worked like that in older games where you give it to a Pokémon to hold and that happens.

Answer 1

If any non-fainted Pokémon in the party holds an Exp. Share, the total experience earned when an opposing Pokémon faints is split in half, with 50% evenly distributed between all non-fainted Pokémon who participated in the battle and 50% evenly distributed between all non-fainted Pokémon holding an Exp. Share. In Generation III and IV, any Pokémon that gains experience also gains all EVs awarded from that battle;
