Nightmare team with Dooku?

I’ve used him. He’s fine. He’s too squishy though imo. Palp, Nihilus, Thrawn, Sion are the most important on the team. The last spot is flexible. I think Vader is overrated and isn’t necessary. But I’ve used everything in that last spot from DT, Magma, TFP, Dooku, Savage, GK, SithTrooper, etc.. All works on offense. So take your pick.
