Tyvokka vs. Micah Giiett

Tyvokka was a Wookiee Jedi Master and mentor to Plo Koon
Micah Giiett was the mentor to Bultar Swan.

who do you think would win?

Let the Wookie win.

Because Wookiees automatically have that fighting behavior in them (i guess you could put it that way) so he could possibly win.
