Harsh Mercy (Onslaught #39) is a white rare sorcery that forces each player to pick a creature type and then destroys all creatures not of the chosen types. It prevents regeneration for the destroyed creatures, making it an effective board clear against decks with diverse creature types. Debuted in the Onslaught expansion as a rare sorcery with tribal-filtering effect.
