Doomsday Excruciator Duskmourn Rare creature Doomsday Excruciator slots into Mono-Black decks as a finisher
Sandman, Shifting Scoundrel (Green) Sandman is a landfall-focused commander with plenty of potential
Whether you look for a flare as a free spell, a fetch land, or a feline (namely Ocelot Pride), you could land on a great boost for your Modern deck
As with Sacrifice, Burnt Offering is great with cards that have high mana values that you can play on the cheap, such as those with Affinity or those that cost substantially less if you fulfill a certain condition, like Emrakul, the Promised End, Avatar of Fury, or Avatar of Woe
Stuff like Snuff Out or Dismember are already heavily played cards, but here, you get to draw a card from them because you lost 4 life, and you also get to drain your opponents for 2 life, offsetting your life loss
That three extra mana you didnt have to actually pay can now be spent on a threat like Teferi or Phlage, double-spelling way ahead of what would normally be possible with basically no downside
