Luke and Yoda run a Dark Side gauntlet (read the description)

Two most powerful Jedi of all time take on Dark Siders.

They are both at their peak so FotJ!Luke and Prime!Yoda.
All others are also at their peak, unless specified otherwise.

Luke and Yoda get full power and health restored after each battle.

Setting: Mustafar

No amp/prep time.

Round 1: They fight teams.

1. SoD Maul, Ulic, Wyyrlok and Wrath II
2. Orbalisk Bane, Traya and Dooku
3. FE Malgus, Tenebrous and Nox
4. RotJ Vader, Krayt Reborn and Exar Kun*

Round 2: They fight duos.

1. Talzin** and Gethzerion**
2. Vitiate*** and Plagueis
3. Caedus and RotJ Sidious
4. DE Sidious and RotS Sidious

Round 3: They fight individuals.

1. Nihilus
2. Ziost!Vitiate
3. The Son

* Exar Kun gets his amulets.
** Talzin and Gethzerion get their Dathomir feats.
*** Here Vitiate is at his physical peak.

How far do they go in each round?

The Sidious duo is an extremely difficult fight, but they should clear everything except the Son imho.

Clear Round 1 with ease.

Clear Round 2. With difficulty due to DE Sidious and ROTS Sidious. But I think Luke can beat DE Sidious so he can help Yoda.

Clear Round 3 with extreme difficulty. Luke having obtained the power of the chosen one is the only reason they clear 3.

I think they could pull off everything except the Son.

Prime Luke > DE Sidious
Prime Yoda > ROTS Sidious

Why is Vitiate in individuals? He would loose to either ROTS or DE Sidious. Against Luke and Yoda combined it would be a stomp.

Nihilus would be even stomped harder as he isn't even Vitiate's equal. Luke and Yoda could TK him to suck his own dick (if he even has it).

Luke and Yoda vs. Son is interesting.

And mostly depends on whether or not Luke can go Oneness. He's going to need it. Not sure how much Yoda is even helping at that point, short of Battle Meditation to boost Luke a little more. Maybe throw some Force Harmony in there. But it's mostly Luke with Oneness with some amps from Yoda trying to fight Son.

They clear everything else without a problem. Tough as Ziost Vitiate is, he can't stand to the Force Light Wall Luke and Yoda would hit him with. They can take down a spirit.

1. SoD Maul, Ulic, Wyyrlok and Wrath II
2. Orbalisk Bane, Traya and Dooku

Either of them solo without much difficulty.

3. FE Malgus, Tenebrous and Nox

Tenebrous is an unknown, except that he's canonically weaker than Plagueis. Either has a shot of soloing, and either can easily tool any two, so they easily win.

4. RotJ Vader, Krayt Reborn and Exar Kun*

Easily trash.

1. Talzin** and Gethzerion**

Talzin ~ Yoda, but Luke > Gethzerion. They win.

2. Vitiate*** and Plagueis

Yoda > Vitiate and Luke >> Plagueis.

3. Caedus and RotJ Sidious

Yoda > Caedus and Luke > Sidious.

4. DE Sidious and RotS Sidious

Luke > DE Sidious and Yoda <= RotS Sidious. I'd say the gap between Luke and Wankatine is greater than that between Yoda and Sidious.

1. Nihilus
2. Ziost!Vitiate

Lol, either of them solo.

3. The Son

They get curbstomped.
