Undercity Scrounger

A death converter dressed as a mana rock. The 1/4 body is the tell: this is not a creature meant to attack but one built to outlast the board it feeds off of, sitting behind four toughness while things die around it. The gate on the ability, requiring a creature to have died this turn, is what pins it to a narrow home; it does nothing in a vacuum and everything inside a sacrifice shell that churns bodies. That constraint aims it squarely at aristocrats decks, where each dead creature is already earning value elsewhere and the Scrounger quietly turns the same trigger into ramp or fixing. The Treasure it makes is flexible: you tap it, then can crack the token for a mana of any color right away or bank it, so it can smooth a later turn or accelerate the current one. Read that way, it is less a ramp piece than a value amplifier, converting a resource you were spending anyway (creatures) into one you can bank across colors. The artifact type on the creature itself is a small but real bonus, giving it relevance wherever artifacts entering or leaving matters. It rewards a specific engine rather than a generic curve, which keeps it conditional, but inside that engine the ceiling on repeated activations is high.
