He also has dialogue for when you destroy half his team, and when he destroys half your team. I also found some new dialogue for when his turn begins and if you destroy his monsters--usually if he has an advantage.

(if he destroys half your monsters) Hmmm... I should have been able to dispose of his army quicker...

(if duel is going well) Ha ha ha... Are you sure you want to face me with those pathetic monsters?
(if duel's going well) I’ve had practice matches that were more competitive, Yugi!
(if you hit him hard, but he’s still in the lead) Heh. Lucky hit.
(making a heavy attack but he’s still in the lead) Heh... I can sense your desperation...

And the best one of all...

(if you’re making a comeback) I let you have that one to be nice, but don’t expect me to be nice again!
