Ashnod, Flesh Mechanist

The historical Ashnod was an artificer who fed corpses into the engines of war, and this design commits fully to the metaphor: a one-mana body whose whole purpose is turning dead creatures into resources. The attack trigger converts a spare creature into a Powerstone, the mana-generating token tied to artifact-heavy strategies, which means her aggression is really a conversion loop dressed as combat. Deathtouch on a 1/1 keeps that loop honest in the red zone, since even a trade during an attack still fills the tank. The graveyard activation closes the cycle by exiling a dead creature card to mint a 3/3 Zombie, so the same bodies that fueled the Powerstones on offense become the fodder for a second wave of colorless artifact creatures. What makes the card cohere is how tightly the sacrifice, the mana, and the recursion feed one another: every creature she uses moves through three stages of value (attacker or blocker, then Powerstone fuel, then graveyard fodder for a bigger body). She is a black aristocrats piece routed through artifact production rather than life drain, which is an unusual translation of a familiar archetype: the death payoff is a rock and a beater instead of a Blood Artist trigger. Small, cheap, and built to be built around, she rewards a deck stocked with expendable creatures and a plan for spending the Powerstones she leaves behind.
