Vile Requiem

A wrath you have to build rather than draw, funded one upkeep at a time and detonated when the scale is finally worth it. Each turn you may add a verse counter, and the sacrifice clears that many nonblack creatures with no regeneration to bail them out: sit on it through three upkeeps and you erase three bodies at once; cash it in early and it's an overpriced single-target kill. That tension is self-imposed, because the counters accrue only on your own upkeep and the enchantment does nothing visible while it ticks, so an opponent who reads the threat can deploy creatures one at a time or pressure you into firing before it matters. The sacrifice itself carries no timing restriction, which is where the design earns its keep: hold up the activation, let the board overcommit, then sweep at the end of an opposing turn or after a pump spell resolves. The nonblack rider is the other half of the idea, a sweeper for the mono-black deck that wants its own board left standing while everyone else's collapses, the color-asymmetry logic that runs through black's removal lineage. What dates it is the charge-up. A sacrifice engine that needs three or four turns of setup to outscale a single removal spell belongs to an era that could afford to telegraph itself, though the core notion of a board wipe you stockpile remains a clean expression of what these slow-charging enchantments were after.
