Who is the best duelist/deck ?

[Cristadia]

Hello, Who do you think is the best duelist in the game ( challenge mode ) ?

I've begun the game recently, I play only yugioh duel monster mostly, so for me the best duelist is Yami Bakura, Yami Marik in the other hand is very weak, I'm disapointed konami give him weak decks ...

burning abyss is pretty good and effective
