Karn's Sylex (PDMU-234p) is a legendary artifact from the Dominaria United Promos set. It prevents players from paying life as an additional cost for spells or activated non-mana abilities and can be tapped with X and an exile cost to destroy all nonland permanents with mana value X or less. As a high-impact reset tool, it functions as a sorcery-speed board wipe that scales with the X payment and requires exile to activate.
