How to Defeat Elite Four Lucian

Mr. Mime (Level 59): This Pokémon uses Reflect and Light Screen with its Light Clay to weaken your attacks for 8 turns. It also has Psychic and Dazzling Gleam. Ghost or Steel-type Pokémon are recommended, but be aware that its Filter ability will slightly reduce their effectiveness.

Girafarig (Level 59): This Pokémon can also use Light Screen and Trick Room, which makes slower Pokémon go first for 5 turns. It has a Mental Herb to prevent interruption of its moves. Its attacks include Psychic and Thunderbolt. Use Dark or Bug-type Pokémon. Avoid Grass-type moves due to Sap Sipper.

Medicham (Level 60): This Pokémon focuses on power with Zen Headbutt and High Jump Kick for STAB. High Jump Kick deals significant damage but will hurt Medicham if it misses. It also has Thunder and Ice Punch for coverage. Ghost and Fairy-type Pokémon are strongly recommended.

Alakazam (Level 60): Alakazam is equipped with a Life Orb, boosting its damage output, and Magic Guard prevents HP loss. It can use Nasty Plot to significantly increase its Special Attack. Its attacks include Psychic, Future Sight, and Shock Wave. Dark-types are the safest choice against Alakazam.

Bronzong (Level 63): Lucian's ace is Bronzong, which is very tanky with few weaknesses. It can use Trick Room, allowing it to move first if you have a slower Pokémon. Its attacks include Gyro Ball for STAB, Earthquake to counter Fire-types, and Payback to annoy Ghost-types. Dark-types are extremely helpful here. Avoid Ground-type Pokémon due to Levitate.
