Be'lakor would be the only one who can summon due to the alignment restriction also applying to summoned Daemons, and he needs to always be on the move.
You can, of course, just use a majority of CSM and ONE unit of daemons and give all the same mark. Then summon in some more daemons.
That’s pretty lame, you are forced to spend CP on a second detachment to use the army. I don’t think it would have been game breaking to have CSM and demons in a single detachment with the existing restrictions the army has already.
You´re totally right.
