The deck revolves around committing crimes as frequently as possible, meaning it constantly targets opponents, their permanents, or cards in their graveyards to trigger Marchesa's ability. Each crime paid for with one mana filters the top two cards of the library, turning a stream of targeted interaction into a powerful and repeatable card selection engine. The strategy leans into blue, black, and red's natural tools for targeting — counterspells, removal, and direct damage — so that nearly every piece of interaction doubles as library filtration and hand advantage.
