Unfortunate Accident

A single black instant that does nothing until you fund it, then bends toward whichever half of the game you need. Pay the line and it kills a creature; pay the line and it leaves behind a 1/1 Mercenary that pumps your team; pay both and you clear a blocker while deploying a body in one cast. The split is the point, because those two effects answer opposite impulses: destruction wants an enemy target and a reactive window, while the token wants your own board and a proactive, developing turn. Packaging both under a single mana value lets you decide which impulse to serve at the moment of casting rather than while drafting your hand. That the token's pump only fires as a sorcery keeps the proactive half from doubling as an ambush combat trick, holding the two modes in their separate lanes. Everything here rewards commitment: because the base spell has no built-in mode, you are always paying full freight for whatever you choose, never cantripping into flexibility for free. The floor is a dead card in hand when you cannot afford either additional cost; the ceiling is a two-for-one that removes and develops in the same breath. Flexibility priced line by line, with no discount for the privilege.
