Given that Profane Command is in my cube and I cut Harrowing Journey a while back, I'm hopeful that being able to cycle for 3 and decent on 4 will make this a good card and make people want to draft it. Black rarely gets reach, so in normal environments, people won't be playing around this in a race or a board stall situation.
Braingeyser meets Profane Command first effect.
You can either fill up your hand or use it to finish off an opponent low on life. Black Devotion can use it.
Older Magic as a Board Game: Panglacial Wurm , Mill
Probably too slow elsewhere though. Maybe it could be a 1-of in a Standard mono-black aggro deck, where Nyx could power it up late game.
