Sanguimancy
The conversion problem this card sets out to solve is real: a mono-black devotion deck builds toward a board of permanents that bristle with black pips, and that board is doing nothing for you in topdeck mode once the dust settles. Reading those pips as a card-draw multiplier is the clean answer. The closer this design's lineage runs is to the black draw-engines that have always asked you to pay in life: the difference is that Night's Whisper and Sign in Blood charge a fixed two cards for a fixed two life, while this scales both sides off the same number, so a developed board can refill a hand in one cast. The catch that keeps it honest is that the same devotion count governing your draw also governs the bill: a board big enough to make this draw five cards is a board taking five life to do it. There is no scry, no choice, no way to dial back the second X if you are low. It is the bluntest possible expression of the devotion-as-resource idea, which is also its limit: it does nothing in an empty-board top-decking situation, the exact moment a control deck most wants to draw cards. It works as a payoff spell for a deck already winning the permanent-count race, and reads as filler everywhere that race is not being run.
