Wayward Servant

The drain engine of the white-black Zombie deck, and the piece that converts a wide board into a clock that does not need to attack. Every other Zombie that touches the battlefield (cast, reanimated, embalmed, or made as a token) feeds the same two-point life swing, which is what turns a go-wide aggro strategy into something closer to an attrition grind. The numbers per trigger are small, but the design intent is the multiplier: the more Zombies a deck can produce in a single turn, the more the trigger compounds, so it rewards token generators and recursion over fat single bodies. The drain-and-gain split matters too. It is not pure reach like a sacrifice-payoff aristocrat; the life gain offsets the racing math against other aggressive decks, letting a Zombie pilot trade attackers freely while still pulling ahead on totals. That makes it the connective tissue between the tribe's two natural modes: the swarm that wants to attack and the value engine that wants to keep refilling. The body is incidental, a 2/2 that holds a flank while the trigger does the work; with a real Zombie shell behind it, the deck can win without ever finding a dedicated finisher.
