Team 1 10/10 in an extremely long and brutal fight.
If Valkorion tags Revan, Vader, Exar and Karness, DE Palpatine can deal with Galen and Krayt in the meantime. Palpatine would be given hell by this duo, but he would eventually win, and come to aid Valkorion.
And I can see Valkorion killing these four on his own. None of them can resist his Force power. Although it's unlikely Valkorion would kill all four before Palpatine finally kills Krayt and Galen.
