Well, to get back on topic......
To look at a potential way this fight could go down.
Sadow V.S. Zannah ; Wyrrlock V.S. Nox
Sadow V.S. Zannah could go either way. Sadow is skilled with illusions though I doubt those will fool Zannah regardless. I would be inclined to go with Sadow, unless Zannah is able to conjure her Dark Side Tendrils and annihilate him, in a close fight. Personally I am unfamiliar with how long it takes to use this ability though I feel Sadow could pressure Zannah with force abilities to keep her from utilizing it effectively. Though arguments for the opposite are welcome.
Wyyrlok V.S. Nox is an interesting match-up in my opinion. Wyyrlok is damned impressive at illusions and mental assaults, as well as Force lightning. As well as being a very good duelist as he held his own against Krayt for a time. However these are Force abilities Nox's ascent to power gives him magnitudes of defense against, and Wyyrlok is hardly one to rush in for a duel. Specifically Wyyrlok's mental assaults. In this case I feel the sheer uselessness of Wyyrlok's most potent techniques against a mentally-fortified, Mother-Machine-Rebuilt Nox would gives Nox a crippling advantage over Wyyrlok. Ultimately leading to a hard-fought, but achievable, victory.
After that, Nox V.S. Sadow I have no idea currently. Of course I appreciate others elaborating on where I may be incorrect, and thoughts on the likelihood of this scenario.
