The Kihraxz is really going to help Xizor. Its a ship with 5 hitpoints and is throwing 3 attack dice out. Its also got a great dial and you can fit 3 of those suckers with a kitted out Xizor.
Kenkirk with the Emperor kind of scare me. Add Isard and its two evades a turn even when bumped. You do have to wait til shields are down, but that happens silly quick anyway. Only thing that's going to shut it down is stress.
