Paroxysm

A red Aura that turns the top of your own library into a recurring gamble against your own creature: every upkeep is a coin flip weighted by your land density, with a land flip killing the enchanted creature and anything else swinging it +3/+3 for the turn. The design is a piece of red's old "you cannot have nice things" philosophy, the same vein as cards that grant a temporary buff with a fatal string attached. Notably, the timing trigger keys off the enchanted creature's controller, which is the genuinely interesting axis: drop this on an opponent's creature and the destruction risk lands on them, on their upkeep, dictated by their deck's land count rather than yours. As removal it is unreliable by construction (a creature deck running few lands flips into a +3/+3 monster more often than it dies), so the card reads less as a kill spell and more as a curse that occasionally pays off, occasionally backfires, and always cedes the choice to the variance of the library. It belongs to a school of late-90s red enchantment design that prized flavor and chaos over efficiency, the era of cards that made the board state a dice roll rather than a calculation.
