Blighted Shaman

A conversion machine in the shape of a fragile body: it turns standing resources (lands, dying or chump-blocking creatures) into combat math on demand, which is why it reads as a sacrifice outlet first and a pump source second. The tap cost is the structural ceiling here. Both abilities require it, so you choose one activation per turn, either eating a Swamp for a single point or eating a creature for two, and the choice forces a real read on which resource you can least afford to keep. The fodder-eating mode is the interesting half: any creature is fair sacrifice, so a blocker about to die, a token, or a creature already marked for death can be reinvested into a survivor or attacker before it leaves the board. That makes this Shaman a release valve for board states on the verge of collapse, banking the value of creatures that would otherwise be wasted. Black's pump-by-sacrifice idea would recur across the color's history in various shapes, but this is an early, unsubtle take: no menace, no recursion, no death-trigger value attached to the bodies it eats, just a tapper that converts your own dying creatures into temporary stats. It is a card about wringing one last point of pressure out of a losing board, and the tap requirement, capping it to one swing per turn, is the discipline keeping a sacrifice outlet from spiraling.
