This team would require 4 main toons (Emperor Palpatine, Imperial Probe Droid, Deathtrooper and Grand Admiral Thrawn).
To make this team work you, theoretically, need to make your Emperor Palpatine the toon that goes first on your squad. Then use his healing ability which in turn will drain health from the other toons including the Probe Droid. Have your Probe Droid go next and use his self destruct ability to remove an enemy from the enemy team. Have Deathtrooper use his terminate ability to inflict Deathmark upon another toon and use Thrawns Fracture ability to hit that enemy 4 times thus triggering Deathmark to deal extra damage 4 times to wipe that enemy. From there on your only have 3 enemies to deal with making the battle pretty much a home run.
If there is any way that this team could be improved or changed I would love to know.
I alook have not been able to test this team so I am not sure if it works.
