Have first zeta, zader, what empire teams the best

I will have to try Bistan also, he needs more gear but not to far off. Does Death Trooper fit in well anywhere here, I have him at 6* 8 gear. No chirp unfortunately. Yeah, I just put my best speed mods on TFP, and got him all the way to 185, lol. So farming more mods for sure. It definitely feels like I am finally chipping away at the brick wall with the zeta though. The fleet challenge sped it up quickly.
