A color shifted (I would argue corrected) Pull from Eternity.. While PFE is uncommon, and there are arguments to be made about the wisdom of creating additional cards that bring things back from exile, this is directly in Black's wheelhouse in a way that PFE really isn't in White's. Also, while it's an unusual effect, it is still strikingly simple mechanically.
Edited to remove the ability to return exiled creatures. While I'm not afraid of making cards that blur the line of bringing back exile, this is the wrong place to do it as it particularly breaks the flavor of the conflict this is supposed to represent. Common is also problematic for that move, though Death's Reach does that.
