Thanks for the clarity.
Yea I thought of Red Corsairs. It's actually what I used to play previous to Black Legion pre-codex update. The good news of Knights + RC's is the CP stuff. The bad news is Huron on foot, trying to pass a warpcharge 8 psychic test 12" away from the target is probably going to give me issues. But it's still an option for sure. And at 360 I'm getting..... 8 command points + 3 for the super heavy detachment + 3 for battle forged = 14. Not bad really.
It is funny though. I bought and painted up all this Black Legion stuff and... it's not really fitting for me. lol
I still have a large Thousand Sons base of models and obviously I can use my old Huron, and Black Legion marines as "Red Corsairs" so the good news is I can be flexible.
On the thought of the Warpsmith... it's really too bad they didn't make a way for him to repair a Knight.
