Witherbloom Pestilence (Black/Green) Strategic sacrifices, life gain and drain Dina, Essence Brewer sacrifices creatures for card draw, but can also sacrifice other creatures to power up another card and gain more life
Cards are divided into Ho-Oh and Lugia boosters
Of course, you can use some sacrifice outlets to generate additional advantages from the likes of Ashnod's Altar or Fling
In the eyes of MTGs rules, Fang is a mono black card, so itd be illegal to have Vanille in your deck
Shoutout to Spikefield Hazard for hitting players and exiling, both relevant lines of text, Song-Mad Treachery in general (It mostly doesn't matter how much a given threaten effect costs, as on a good day it'll be the last spell you cast), and Malakir Rebirth/Sejiri Shelter for being great at the low threat count decks (prowess) that I love encouraging
