One of the things I liked about older editions in comparison to 5e, is that in 5e, all clerics get your standard turn/destroy undead, which makes sense for your archetypical good aligned cleric. But, on eviler clerics, well, it doesn't really make much sense?
But go back a few years, and clerics actually had two options, which they got dependent on their alignment (With neutral clerics getting to pick).
So, heres that, but in 5e. An evil cleric counterpart to the regular channel divinities clerics get.
Of course, since alignment isnt much a game mechanic in 5e, you don't have to be evil to be able to take it. Which makes sense. A grave cleric could see much more value in forcing undead to come to them, rather than having the target of their hunt flee. And by wrestling control away from an opposing spellcaster, they can ensure the undead cant be used against them or others.
