Lethal Exploit

In Commander, Lethal Exploit earns its slot in any aristocrats or token-sacrifice shell — one mana removal that ignores indestructible is rare, and sacrifice outlets are already on the battlefield in those decks. In Pauper, the common-legal removal pool is deep but mostly color-restrictive, and the exploit trigger opens lines with sacrifice-matters synergies at an accessible cost. Modern and Legacy have cheaper, unconditional removal options that don't require a board presence to function at full power, so Lethal Exploit doesn't compete there outside narrow tribal or combo shells. Pioneer sits in a similar spot — playable in a dedicated sacrifice deck, but not a generic removal slot.
