Screams from Within

Most auras die with their host, sunk cost the moment the creature leaves play. This one inverts the logic: the death it eventually causes is also the trigger that brings it back. The -1/-1 grinds down a small body until it dies, the aura returns from the graveyard, and you point it at the next target. Against a board of X/1s it becomes a recurring eraser, a single black card that answers creature after creature so long as something small keeps showing up to kill. The friction is that it only chips one point at a time, so anything with three or more toughness shrugs it off until you stack additional shrinking effects or wait for the board to come down to its level. That patience is the cost: it is not a removal spell you cast and resolve, it is an attrition piece that pays off over several turns and several deaths, which is why it reads better in a slow grind than in any race. The recursion clause justifies everything else about the card, and it quietly rewards decks that can manufacture death triggers or shrink toughness on their own rather than waiting for the opponent to oblige.
