Hint: White mushrooms

If you go into a White room, you will see white mushroom enemies. If you enter a battle with one you will see that they don't attack you. Instead of attacking, wait until you see a light bulb above their mushroom. Then use a lightning attack on that mushroom. After a while, they give you experience points, and a glowing P. If you touch it roulette starts and changes a card into a premium card.

Hint: Elixir

The Elixir will quick-load both your attack cards and your magic cards. To get it help Roo out of the hole in 100 acre wood. He will also add to your journal.

Hint: Defeat Marluxia

To defeat Marluxia you must have maximum health and 820 card power. When that is done, put three or four cure cards. You then have to destroy the two swords. Do not worry -- he will not pay attention to them. Finally, cardbreak him. You will then see the lock on him; then attack. Note: You cannot attack him until you cardbreak him. You can tell you can attack by when the lock shows on him.
