Darth Traya versus the AOTC PT Jedi Council
Which team wins?
I am tempted to say Traya since she slapped around three Jedi masters, each of which were stronger than any member on the (AOTC) PT Jedi council (with the exception of Yoda and Mace).
Factor in her instantkill, and the fact that none of the members on the PT council are strong enough to resist a technique "born of the ancient sith", in which "there is no defence," the battle seems guaranteed in Traya's favour.
So in the end I say Traya wins.
