Easy Riku Defeat
Do you have trouble with the last Riku fight? In order to defeat him,be around level 70 and have about 5 "0" cards and whenever he uses the move where the room gets dark and he jumps off the walls(Dark Aura) or Dark Firaga, use them. It is important that you keep them at the end of your deck so you wont have to search your deck for them. Once you defeat him, go to destiny islands and save it and then go to Castle Oblivion and you face Larxene.
Friend Card Slight Tip
This is for the slights that require friend cards (such as Goofy, Donald, and others). For example, you have Trinity Limit. It requires Goofy, Donald, and any attack card. What you do is wait until you get a Goofy or Donald friend card. When you get it, use L + R and the same for the attack card. When you get the last friend card you need, use Trinity Limit or the other slight that you're using. You get to keep your attack card because it's not the first card for the slight!
Genie Summon Card
Defeat Jafar.
How to beat maruxia & maruxia redux
For marluxia, you have to put about five, six zero cards in the beginning your deck. next put only six, seven, eight, & nine value cards in your deck beside the zeros. and last put the darkside enemy card in your deck & make sure you have enough cp. in the battle, use the darkside card when marluxia uses "double sleight". then keep trying to use trinity limit and other sleights. for marluxia redux, use the same deck, except take away darkside & put in the marluxia enemy card & use the same thing that you did for regular marluxia. i did the same thing, but it didn't work for a few trys. but still worked.
