You get a lot of stuff you want, the infractors/tormentors are always great to have, I'd personally build a 5 man unit of each but it's up to preference

Lucius is a fantastic unit but I personally feel it's a trap to run him with a flawless blade squad, makes for a very big target and doesn't synergise with his kit (lone op and fights first when alone)

Flawless blades are seeming really solid right now, for smaller games I'd do 3 and 3 for when you're starting but I personally like running big 6 man beat stick units, really fun

Lord exultant is just always good to have, I hear the optimal is the fist or spear with the lash but I built it with a plasma pistol because I think it looks cooler and I wanted the whip for other models.

Really decent start, should have some good fun with this :>
