Nice teams.
Still...Exar Kun, DN Luke and DN Jacen ? Against Sion, Sidious and Nihilus ?
Meh. Luke on his own is capable of wasting the entire opposite team on his own. Thanks to the redicously power boost the EU writers gave him. Nihilus will drop down death (either executed by Luke or toasted by Kun) before he can do anything. Sidious falls next and then Sion gets sliced into so many pieces that he won't recover from it. End of story.
Ah well...before I forget it. Nihilus might try to drain them and it's even possible that he will be successful draining one of them to a certain extend before getting his ass kicked. Unfortunatelly Kun might pull of the same ability (as he was equipped with all of Sadow's knowledge most likely containing it) while Jacen and Luke can both "seperate" theirselves from the force which would basically turn them into different versions of the Exile, weakening Nihilus if he tries to attack them.
Not to mention that there is the chance that Nihilus is down on the floor before he's able to move a finger considering who he fights against.
