Spontaneous Combustion (CNS 194, foil) is an uncommon instant from Conspiracy that requires sacrificing a creature as an additional cost. It deals 3 damage to each creature when it resolves, functioning as a small mass-removal tempo play. The sacrifice requirement makes it useful in decks that produce sacrificial fodder or seek to clear blockers while trading a creature for board control.
