I have a simple way of defeating Marluxia in his robot.

1.Have, at least, a 1000 CP.
2.Use level 9, 8, and 7 keyblades. (Physical attribute Keyblades work best).
3.Use three level 7 Cure cards( six if possible) plus a level 6, 7, or 8 Mega-ether and a level 6, 7, or 8 Hi-potion or Mega-potion.
4.Use Vexen.( other enemy cards are optional.)

There really is no easy way to beat Ansem, but here's how I did it.
1. Break his attacks until until you go Dark mode. (Using 0 level cards to break his combos will get 9 points closer to Dark mode.)
2. Attack in such a way as each attack breaks his cards, leading up to the third strike.( the second one stuns him briefly.)
3. Grab Mickey when he appears. Heal when he reloads.( If your really hurting and he hasn't reloaded yet, use Oogie Boogie to slowely recharge some health.)
4. Don't bother with sleights, he'll only break them and then destroy you. If you use Mickey in a sleight to heal you when he hasn't reloaded, he'll break it before you get healed.

Good Luck with Marluxia and Ansem!
(by the way, you don't have to be level 94 to beat Ansem. I beat him at level 41 and with a max DP of 18. Marluxia in his robot is a hell of lot easier than his image. The deck you beat Marluxia's image with will work better against him Personally!)

Secrets
Unlimited Moogle Points
For this secret open two connecting rooms, and wipe out all the enemies inside. The places were moogle points are regenerate after you leave a room and return, but the enemies don't.

Just go back and forth in those two rooms to get all the moogle points you want. I find that you get about 2000 in about 5 minutes or so, depending upon how lucky you are.
