Rosalina And Luma vs Lucina

In the matchup against Lucina, leverage Rosalina's Starbits to zone her out and control space effectively, especially since her sword attacks can out-prioritize many of your moves. Be cautious about Luma's positioning; if Luma is knocked out, retreat and use back air to maintain distance while looking for opportunities to summon Luma back. Utilize Rosalina's down special to create a barrier and disrupt Lucina's approach, and remember to capitalize on her slower movement by punishing overcommitted attacks with grabs or aerials. Stay mobile and focus on maintaining stage control, as Lucina excels in close-quarter combat.
