Archfiend of Despair

Most life-loss payoffs in black ask you to deal damage and then double it, or to drain in fixed increments. This Demon does something stranger: it watches the whole turn and bills the total back. Whatever an opponent has bled in a turn (combat, burn, painlands, fetch cracks, their own self-inflicted card draw) gets charged again at the beginning of each end step, which means the doubling is not deferred to that opponent's turn but resolves at the end of whichever turn the loss happened, including yours. Attack on your own turn and the second helping arrives at your own end step. The static life-gain lock closes the obvious escape hatch, so the symmetry runs one way only. The mechanic rewards offense you were already committing to rather than dictating a specific combo, which is what separates it from the loop-piece drain engines that pair with sacrifice outlets to mill an opponent's total in a single pass. Here the work is additive: every point that lands gets counted twice, so a board that pressures the life total at all converts that pressure into a clock. The 6/6 flying body and eight-mana cost place it in a deck already winning the damage race; it is not a stabilizer but an accelerant. The design's quiet sophistication is the breadth of "life that player lost this turn": it does not care about the source, only the ledger, which punishes a wider band of incidental life payments than any targeted drain spell could.
