Bone Shards

Unconditional removal that answers both creatures and planeswalkers for a single black pip should overshoot on rate, and the correction lives in the casting cost itself: sacrifice a creature or discard a card. That additional payment demands you already hold ammunition pointed in one of two directions before the spell resolves. The sorcery timing steers the sacrifice half toward a planned main phase: a spent token, a body whose final job is stocking the yard, so the removal doubles as graveyard fuel on its way out. The discard half converts surplus (an extra land, a stranded high-drop) into board interaction rather than clutter. Line it up against Hero's Downfall or Vraska's Contempt, which buy the same broad target range for more mana and no obligations; this presses the cost down to one pip and repays the discount through what it eats on cast. Sitting beneath it is the black attrition premise that resources are interchangeable: a card in hand and a creature already committed are the same currency, and this spell spends either one to kill a creature or planeswalker at the sharpest rate the color offers when the bill can be split two ways.
