Marluxia is easy just get a hole bunch of nine and cloud cards to kill him.Make sure you use Cross Slash and not Omnislash,because you will just hit his flower buds.Hit him with Cross Slash when your on the platform.Jugment helps as well, when you cant get to him.When he's about to jump brake him with a nine card. Don't forget to bring lots of cures,and megalixars with you.
