The rest of this cycle are mostly "Do some symmetrical negative thing. Undo most of the negative effects to you." So I wonder if, rather than doubling your life total, this could give you a creature back, like Phyrexian Rebirth? It's a bit similar to Faith's Oblivion but the main symmetrical effects of those two are already fairly similar anyway.
Honestly it was 3 in the morning when I design this and I was mostly concerned about the flavor text
hmm. You're right. the W and B symmetrical effect is too similar. Also double life total is weak. Back to the drawing board =D

I'm not sure what "Faith's ~" is
