I'm aware this battle has been done before, but I feel having Sidious at his peak, and Grandmaster Luke makes the other combatants contributions lesser. So here it goes
Yoda and Luke Skywalker
Luke Skywalker has feats up to and including Dark empire.
Darth Plagueis and Darth Sidious
Plagueis at his peak.
Assume perfect team synergy.
EU feats are allowed.
Standard Gear and Morals
Win by Death, KO, Incap or Submission.
No offensive force powers.
Offensive force powers are allowed.
Korriban Dueling roof.......
Start 50 ft away visible.
Who wins and why?
