Good point guys.
But Mace didn't defeat Vastor in blade-to-blade combat.
If you remember he used the Force and hurled one of the fallen Akk Gaurds Vibro-shields at him after bouncing it off the wall behind him.
Mace stated he could never have defeated Vastor is a duel because Vastor was younger, stronger and more viscious.
Actually, the way I remember now was Mace said he couldn't beat him on his best day.
So, maybe rethink your answer? 😉
This is really tough. Mace lost to Kar the first time and only won the second time because he found Kar's Shatterpoint. Yoda's a tiny but stronger than Mace, but not much. But Kar can't use Offensive Force Powers, which makes Yoda have a slightly better chance. So I guess maybe Yoda wins but I'm really not sure, it'd be really, really close.
How the hell is "Yoda wins!" a good point?
