Bringing up Wario is actually kind of important here because Wario is a super floaty character who is faster in the air than on the ground with great combo ability, a good recovery, but garbage range and a lack of reliable kill options to balance him out. Note how this is the opposite of most sword fighters. Most sword fighters have good range and kill power but typically have crap recoveries unless they're light. Stat wise, Brave has more in common with Wario than Toon Link.
Note how both Mario and Wario have better aerial options that grounded options. What's even more interesting is Brave's slide because it gives the character even more incentive to be in the air than on the ground. Most swordsmen space in the air or approach in the air to lead to grounded options. They are typically zone breakers. Characters like Mario and Wario typically approach in the air to open options to get their opponent in the air and try to keep them there. Mario and Wario also typically try to manipulate you into their space and capitalize on mistakes, again, because their range sucks and they don't have a lot of kill options. Characters like Marth and Roy get into your space and can run away and space when in the lead because of their range.
What's the point of this? The point is that Brave is of average speed and but floaty. Consider the following:

Let's look at the swordsmen with high aerial speed. Roy and Chrom. Fast with great combo ability and kill power, terrible recovery. Where's Toon Link? Tied with Rosalina and Metaknight for 40th. We've already gone over Metaknight and Toon Link's playstyle as swordsmen. Where's Mario? Tied for 12th for aerial speed. Big difference. What about run speed?

Brave and Mario are roughly the same, tied with several characters for 32nd. Toon Link is 24th, Metaknight is 14th. Again, very different than Smash's "floaty" swordsmen. Once again, despite the size similarity, it's not likely that Brave will play like Toon Link because he doesn't have the stats of a swordsmen, he has the stats of someone who fights hand to hand or has mid range projectiles.
