Team 1.
Mace would die to either Krayt, Kun's, or Malgus's force abilities but he can hold off either and win a duel.
Revan can likewise beat Malgus or hold off either with his force abilities, and Jacen can defeat any of them.
EDIT: Ironically Bane's tomb may or may not be a nexus, so Kun's gauntlets could be a wildcard as well.
