Magic swords... really... SAO does NOT have magic. How bad can the dub get with its facts...

Anyway, the sword is a boss drop from the 50th floor. If it's the floor boss, it wouldn't be surprising if Elucidator would be unmatched for a long while, seeing as quarter bosses are REALLY hard. However, it would eventually be outdone by some sword on a higher floor, unless the sword was constantly enhanced and even that has a limit. And even so, I don't remember any mention of it being THE best in the game. Especially since, as I've already said, it would eventually be outdone.

However, Elucidator is a unique item, since it's a uniquely named boss drop.
