One of the Modern Horizons 3 cards is Necrodominance, a "fixed" version of Necropotence:
This is weaker than Necropotence in some important ways, the most significant of which is probably that Necrodominance does no allow its controller to pay life in response to removal. Necrodominance also limits its controllers hand size, but that's probably not as big of a deal as people might think at first glance.Quote:

Skip your draw step.
At the beginning of your end step, you may pay any amount of life. If you do, draw that many cards.
Your maximum hand size is five.
If a card or token would be put into your graveyard from anywhere, exile it instead.
Another notable difference between Necropotence and Necrodominance is that Necrodominance actually draws cards. So Sheoldred, the Apocalypse is an obvious synergy ( and draw hate is more of a liability).
My understanding is that the were basically two flavors of Necropotence decks: combo decks that would use the massive card draw that Necropotence provides to find combo pieces, and more tempo oriented decks that would combine the massive card advantage that Necropotence provides with efficient threats.
Regardless, Necrodominance provides potential for massive card advantage at a relatively modest life cost which is a fundamentally potent thing that can fit into a variety of game plans.
For example, it should be quite potent in combination with effects like Smallpox or Collective Brutality that rob both players of resources, and cards like Chrome Mox or Dark Ritual that convert card advantage to speed. In many ways it should readily slot into a smallpox deck.
Another option might be some kind of black/white scam deck. Ephemerate and Cloudshift will work with evoke creatures even if necrodominance is in play, and Solitude with flash and lifelink fits with the necrodominance pretty well.
Madness has some decent synergy with Necrodominance since it partially works around the graveyard to exile replacement effect, overdrawing is a natural discard outlet, and necrodominance is a pretty solid top-deck when hellbent. The interactions with from-the-graveyard stuff like Vengevine and Ox of Agonas aren't ideal, but it still seems like Necrodominance can offer a lot of stuff that a Hollowvine/Madness deck might want.
I'm trying to compose possible deck lists, but it's a little tricky to come up with card engines to complement the Necrodominance. This is an attempt at a smallpox kind of thing:
18 Swamp
4 Chrome Mox
2 Dark Ritual
4 Throughseize
4 Nethergoyf
4 Orcish Bowmasters
4 Smallpox
4 Dark Confidant
4 Hymn to Tourach
4 Necrodominance
2 Liliana of the Veil
4 Beseech the Mirror
2 Sheoldred, the Apocalypse
