ill post the one from the guide:
The battle against Luxord brings something new to the table Rather then attacking an enemy's HP, this battle is fought against Time. Both Sora and Luxord have bars that represent time. Whoever's Time bar is emptied first loses. Unfortunately, this doesn't prevent Sora from dying if his hp reaches 0.
This battle is a mind game in more then one aspect. Being a gambler, Luxord is fond of changing Sora into a card and into a die. Magic and Items are unusable in these forms. There is no proper response to being shape-changed; just bounce or glide up to him and attack to apply pressure. This kleeps him from inflicting too much damage when you cant heal.
Watch for an oppurtunity to flip the cards with the Flip Reaction Command while focusing your attacks on Luxord. Watch for him to turn himself into a card. When this occurs, keep track of Luxord's card as it is mixed in with various others. When the cards stand up use the Flip Reaction Command on him.
Toward the end of the battle Luxord spreads cards around the arena floor. Jump around to dodge the cards he throws as he teleports around. If you have obtained the Final Form's Flide Ability, use this to keep him at a distance.
During this fight you also get the oppurtunity to use the begin game reaction command, which turns the text in the command menu into X's and O's. The idea is to press the button on an o as they rotate by to avoid being cursed and turned back inot a die or card.
