Riku's second Replica Riku fight is by far the most difficult fight in the game. And not even so much because you can't heal but once, it's because of the crappy order Riku's card are in. If it were like some of his other boss decks where all the zero cards were at the very end and you could just quickly scroll back and use one it might be better, but they are just scattered in the deck, and I think there are only like three of them. Thank goodness for the Malificent and Jafar cards, that's all I've got to say.
