All you need is a demon in play to draw cards and siphon life each turn, and you can even create one when you unlock Ritual Chamber
Screaming Nemesis Screaming Nemesis turns damage against it into damage for your opponentsor their creatureswhile it shuts down lifegain entirely once it hits a player
An efficient sweeper that hits multiple permanent types and will often leave you mana positive, Culling Ritual has found a home in every single Golgari deck I own
Plus, it's a huge boon in Commander because no longer do you have player elimination
But the spell/creature side of these are more efficient than the average from the Zendikar Rising modal double-faced cards and the mono-colored ones can enter untapped if you pay life, so I think many will find a home, and not just in Goblin Charbelcher decks
