MTG Salvation

Her +1 creates board presence/protection and starts dumping cards into the grave for embalm, aftermath, or her -3.

Her -3 gets your best dude back from the grave, and can be used immediately as she's cast if you really need that beefy card you cycled in the early game. Oh yeah, discard costs and cycling are things that easily dump creatures in the grave for you to reanimate.

Her -7 is at worst, Wrath, at best, a one-sided Wrath. Solid.

I think she does plenty in the right deck. Walkers that can easily protect themselves and generate advantage generally see play, and she does both.

I mean Unburial Rites was a big thing because it allowed 1 card to be 2 recursion spells. I see this as its either unburial rites or your self mill to then unburial rites. You will always be able to get Rise from the grave out of this card when it lands if you want, and if you don't want then you can get a 2/2 and mill 2 to find what you want to reanimate. The real way I see this being played is with cycling and discard draw cards. You can just slot her into the gearhulk refurbish deck and have her act as more reanimation.

+1 immediately protects itself, and sets up its -3.
-3 can potentially immediately net you ridiculous value + sets up protection.
-7 can give you a one-sided wrath after being in play a few turns.

Aside from general playability as a 2-of type thing, I also see it as a sort of (albeit more vulnerable) Unburial Rites 2.0. If we get any more Entomb effects, it could be pretty devastating. As-is, we've already got some great choices with Grim Flayer, et al.
