Luxord is screwy man,

First off have a good keyblade equiped.
Obilivion is good.
Okay, start off by hitting him rapidly (beserker ability), he will then turn you into a
dice, litteral role around and avoid luxord.
When you turn back do the same, he will then turn himself into a card, watch the card he
is and then attack it, choose isely, coz if you don't he will attack you from within the
card, repeat this, im don't think he does anymroe, he's a preety easy boss
