The killing range tells the whole story: power 2 or less catches the small creatures black has historically struggled to interact with cheaply. Mono-black removal of the era ran heavy on edicts and life-loss kill spells; targeted destruction that didn't care about color or fear was rarer, and pinning it to a tight power threshold is the discipline that holds the rate down. You pay for precision against the bottom of the curve, not a clean answer to anything. Cycling is the part that earns the slot. A card that destroys nothing in a given matchup (no small creatures to point it at) is a dead draw, and the discard-to-draw outlet converts that liability into a fresh card for two mana. That changes the deckbuilding math relative to a straight removal spell: the worst case is never a blank, it's a cantrip, so the variance that makes narrow removal a gamble simply isn't there. Cycling was the load-bearing mechanic of its set, attached to roughly a card per slot to smooth out draws, and this instant demonstrates the design intent cleanly: removal that wants to be in every game and a card-flow valve for the games where it isn't, both stapled to the same spell.
