Measure of Wickedness

An eight-life timer that you can hand off. The trick is the second clause: any card hitting your graveyard from anywhere, not just creatures dying, exports the enchantment to an opponent, and the end-step sacrifice plus eight-life loss travels with it. So the card is built as a deliberate hot potato. Whoever holds it at their own end step takes the eight, and the way to pass it is to feed your own graveyard: a fetched land, a cycled card, a discarded spell, a self-mill trigger, any of them resets the clock onto the other player. What balances the design is that the very actions a black deck takes anyway (discarding, milling, sacrificing, cycling) double as the off-switch, which means the threat is sharpest against an opponent who cannot fill a graveyard on demand and toothless against one who can. It reads as a removal spell pointed at yourself with an escape hatch, and the engineering is in whether you can keep finding cards to bury before the end step arrives. Read it less as a clock and more as a graveyard-interaction puzzle: the loss only ever lands on whoever runs out of fodder first.
