I'd say marluxia on the GBA Chain of Memories, because I used so many sleights that were broken, I ended up with only one 0 lady luck card, and a heal. So I broke a card and hit him, healed, reloaded. This is continued for 30 minuites. Its was really epic.
I also love Xaldin, because gaurding is attacks and learning is SO EASY. He is SUCH A PUSH OVER.
The following game is from Demyx Time, a series of videos by JenxTheJinx
This is how to play the game:
1. You just started the game
2. While playing the game, you cannot think of the game.
3. If you think of the game while playing the game, you must admit you lost the game.
