Loyal Defender

After thinking it over, I have a chance at beating Marluxia if I do something really crazy. 

I'm going to go to Castle Oblivion, make a Save Point and Moogle Shop room right next to each other, save my game...and sell all my cards at the Moogle Shop. Of course, firstly, I'm going to need to get a LOT of Moogle Room Cards, mostly so that I can re-create the Moogle Room and rebuy cards. The cards worth 400 Moogle Points have the highest values. Not only will this ensure that I get a lot of good cards to combat Marluxia, but ALSO that I have a lot of cards to benefit myself during battle so I don't get my ass handed to me. Of course, before fighting Marluxia, I'll need to level up a lot more to earn special sleights to make EXP grinding easier, and make leveling up my CP and HP go by a lot faster. I might have a chance at winning if I.....play my cards right.
