mace can hold his own and possibly defeat dooku. kit fitso can more then hold his own against maul and i dont know enough about malak or agen to make a comment either way.
in fact i think fitso would defeat maul eventually. and mace via vapaad will defeat dooku eventually.
so it comes down to malak and agen. whoever wins that fight will go on to help their allies. that is unless those two are so evenly matched that their duel is lengthy too. in which case either mace beats dooku and helps the others or fisto beats maul and helps the others.
Dooku could hold off Mace for the time it would take Malak to snap Kolar's neck and toss him into the fire. Fisto head goes flying by a searing red blade courtesy of Darth Maul. Mace is then left to work as the personal whipping boy of the Sith, cleaning up the mess Maul left behind and serving Dooku his Appletini. He also has to clean Malak's jaw once a week to prevent infection. Eww, it probably stinks.
I am now seeing Malak as a weak point here. We've seen him kill two nameless, featless Jedi. And this isn't Star Forge Malak either. We know he's good, but he's not Dooku or Mace good, no sir.
I can see Maul handling Kolar or Fisto. Maybe not winning, but handling. Dooku has to fight Mace, which leaves Malak the Unknown to fight the remainder. In deeper consideration, unless Maul can best Fisto or Kolar quick enough, then this promises to turn in the Jedi's favour.
