I have to say that I gotta agree that this episode feels like filler. You could skip it and not really miss all that much story-wise.
That being said, it's also really, really great filler. It's the kind of episode you can watch multiple times and still get a complete story. It doesn't really lead from or into anything else. It's its own little story with some great character development that is non-traditional. As mentioned before the moral isn't that Lion-O needs to be a better person, he already is a good person, as is shown when he fights the Duelist less for his own pride, but out of a sense of justice for all the swords he's taken simply because he can. He just needs to learn that there are more ways to fight than with strength alone, one can be weaker and still find a way to win. An excellent lesson when going up against the likes of Mumm-Ra.
