i remember going through the worlds leveling up sora's hp and cp. I put a couple of 0 cards in the front and end of deck, high number cards, and cure cards. I did fine after i went through the worlds once.
the only manga i like Fruits basket and KH, i watch anime more than reading manga,
a O card, and Curaga. in Re:CoM, Oogie Boogie's card saved my life
