Blood Tithe

Four mana for a six-point swing against a single opponent: drain three, gain three, and walk away. The rate is the whole calculation here, and it has never been quite enough. A two-way swing of life totals at sorcery speed asks the deck to be doing something with life as a resource rather than treating it as a one-time burst, and black's drain effects that touch every opponent at once have mostly moved past flat numbers toward repeatable engines and scaling payoffs. What keeps it from total obsolescence is the all-opponents clause, which is dead weight in a duel and quietly compounds against a wider field: three life lost per head adds up, and the life you gain scales with however many you are draining. That asymmetry is the only axis on which the card argues for itself. As a piece of black's life-manipulation toolkit it is honest and unexciting, a clean drain at a fair price in an era that has learned to ask for more than fair.
