Collateral Damage

In Commander, Collateral Damage earns its slot in sacrifice-matters builds where the creature going to the bin is the point, not the price — think Goblin token engines or Aristocrats shells where every creature death triggers something. In Pauper, it competes in aggressive red strategies as a one-mana removal spell that doubles as a finisher, and the common slot is deep enough that it sees real play. Legacy and Vintage have faster, cleaner options, so Collateral Damage rarely shows up there outside of specific synergy builds. Modern and Pioneer have enough efficient burn that it only makes the cut if the sacrifice is the engine, not just the cost.
