Lucario vs Joker

When playing Lucario against Joker, focus on utilizing your Aura Sphere to zone and punish Joker's approaches, especially when he is trying to set up with his Rebel's Guard. Maintain your distance to avoid Joker's potent combo potential, particularly when he has access to his Arsène, which greatly enhances his damage output. Use Lucario's quick mobility to dodge Joker's projectiles and find openings for your close-range attacks, as well as to retreat when necessary. Remember that Lucario's survivability increases as his health decreases, so leverage your increasing damage to capitalize on any mistakes Joker makes, especially after he commits to a risky move.
