I've watched the whole Yu-Gi-Oh season 0 episodes but not all the final product ones yet. I think I've might've liked Season 0 version of it better but if the Kingdom Duelest Tournament happened after the last episode of Season 0 ( Since in the earlier episodes Kaiba already stole the White Eyes Blue Dragon somewhere in episode 3 ), there might be a possibility to know that either Kaiba died or is still alive since Yami-Yugi used mind crush to wipe out the evil in Kaiba's heart as far as I can remember from the last time they both dueled again before Thief Bakura traps Yugi & the others in some kind of RPG game.
