Host raptorial night lords detachment, jump pack chaos lord with the spoopy murder sword relic or a thunder hammer, a block of Khornate raptors and warp talons.
On the drop, 3d6 charge strat for the warp talons +2 from HR for tagging all the things, nope someone's aura ability say feirros or that tau overwatch thingy, let's get cheeky and drop something into cover near the lord for +4 (+2/+2) to charge with the strat for charging from cover in addition.
Throw a daemon prince as the main warlord in a different detachment with the slaanesh daemon claws and d3 attacks trait, and this spoopy boy can get up to 14 attacks on the charge or bare minimum he gets the same as he did if he didn't have the shenanigans. Lob diabolic strength on him because you're that guy.
Yeah I'm definitely happy with this book, even if it makes CSM a little hungry for CP
most folks can get out a battalion and another little detachment
