Ashiok, Nightmare Muse
The new Ashiok planeswalker isn't meant for pure Mill decks, but it can see play in Control and Midrange lists, ones that can put an opponent on a slow clock by steadily milling them out.
Ashiok, Nightmare Muse could easily replace Ob Nixilis in Dimir Control decks and would do a much better job at controlling the game.
The -7 ability looks super exciting, and it won't take you too long to get there. So there are definitely a lot of opportunities for Ashiok in Pioneer.
