Shambling Goblin

A one-drop whose whole value is in dying, which makes it less a creature than a stored removal trigger you happen to deploy early. The body is incidental: a 1/1 that chump-blocks once, trades once, or just sits as fodder until something asks to eat it. The parting shot does the real work, because -1/-1 to an opponent's creature is reach that arrives at exactly the moment you were spending the card anyway. It pairs naturally with sacrifice outlets and ground-stalling aristocrat shells, where bodies are a resource you cash in for value, and it turns an unfavorable combat trade profitable: their attacker dies, then your dying blocker shrinks the next one. The target restriction is what keeps it modest; the -1/-1 must hit a creature an opponent controls, so it cannot finish off your own marked goblin or push something into lethal on a token you control. It is the most basic shape of the recurring black design where a small creature carries a farewell, the lineage running through chumpable bodies that pick off X/1s on the way out. Plain in a vacuum, mechanically pointed in any deck built to make creatures die on command.
