Link and Lucina are both experienced swordfighters so this would be a tricky battle. Lucina seems to be a lot quicker than the Hero of Time, but Link has many weapons at his disposal. Even if this was just a plain ole swordfight, I would have to take Link in the end. His Master Sword has quite a few powerful swings at his side and his Light Arrows can fend Lucina off if her blade is starting to overwhelm Link. Link has a defense for all of Lucina’s moves, so he can hold out until he wins. Link wins.
