Ravenous Demon // Archdemon of Greed
The transformed side is a deal you keep paying. The front face is a tame 4/4 with a sorcery-speed switch, and the back is exactly what demons of this era promised: an enormous evasive threat whose upkeep clause demands tribute or extracts it from you. Nine damage is a number chosen to be lethal in two or three swings of self-inflicted backlash, which means the engine only works if you keep a stream of Humans flowing into its mouth. That fuel requirement is what makes the design coherent rather than a free flier: it pulls the card toward a sacrifice-and-token shell, where each chump body bought a turn of life and a turn of attacking. The transform itself is a one-way commitment with no built-in path back to the front face, so the choice to flip is the choice to commit to feeding it.
What dates the card honestly is its lineage. The pact-style demon (a body too good for its cost, paid for with a recurring upkeep tax) runs back through black's history of Lord of the Pit and its descendants, where the punishment was always a creature sacrifice you had to pre-arrange. This one folds that tradition into the Human-sacrifice subtheme of its era, narrowing the cost from "any creature" to a specific tribe and tying the demon's hunger to the same tokens that other cards of its era were producing to feed it.
