Fiend Artisan

Birthing Pod, rebuilt to reward the graveyard it feeds. The Pod line was always a linear climb: sacrifice a creature, fetch the one exactly one mana value higher, ratchet up the curve one rung at a time. This activated ability tears the ceiling off. It fetches any creature with mana value X or less, so the search is bounded only by how much mana you can pour into X: a two-drop hatebear early, a game-ending payoff late, off the same card, without ever needing the curve to line up. The body scales off the yard rather than the ability itself. Each activation feeds a creature card into the graveyard (when what you sacrifice is a real creature card, not a token), and it is the count of creature cards there that swells the 1/1 into a genuine threat. That distinction matters to how you build: fodder that stays as a card in the yard grows the clock, while token sacrifices power the search without adding a body. The two-mana hybrid cost lets it slot into any deck touching black or green, and the sorcery-speed restriction keeps the tutoring on your own turn, where opponents get a window to interact before the fetched creature arrives. The result is a tutor engine that doubles as a payoff: dig for exactly the answer you need, and let the discarded husks of the search sharpen the creature doing the digging into a finisher.
