Anakin Skywalker (RotS) vs. Asajj Ventress and Dark Ahsoka

This is Anakin after he turned to the dark side.
Ventress as of The Clone Wars Season 5
And this is Mortis-empowered Dark Ahsoka
BATTLE TO THE DEATH!
Setting: Open Field

I'm going with Sky guy on this one. His defeat of Dooku in ROTS suggests he could take these two, especially since he's not avoiding harming Ahsoka.

I agree, and I think it would be a pretty good fight. Hope to get more opinions though.

I'll go with Anakin.  I can see the team winning in some scenarios if anakin gets too cocky though, at least if this is anakin as of his fight vs kenobi.

Agreed. Though if that were to happen Ventress would do it, she's probably the most tactically inclined and would have a cooler head than Ahsoka or Anakin.
