The last time a deckbuilding rule got rewritten into a payoff, it was the Relentless Rats family, each turning "count your own copies" into a stat engine. This does the same trick with a lore-accurate ceiling of nine, one for each of the mortal men doomed to die, but it swaps the raw self-referential bonus for a snowball. Every copy that enters tempts the Ring, and every temptation (from these or from anywhere else in the deck) drops a counter on the entire Wraith board at once, so the ninth arrival is also the moment the first eight get another size larger. The deathtouch does the work while those counters are still small: a 1/2 is trivially blocked, but a 1/2 with deathtouch means the blocker either dies or the attack gets through, and by the time the counters have accumulated the board is trading up in combat and threatening real damage across it. The wrinkle in the Rats lineage is that here the payoff is a growing battlefield presence rather than a fixed pump, which means an incomplete set of copies is still an engine rather than a pile of vanilla bodies. The flavor of the name (multiplicity, inevitability, a grip that only tightens) and the rule permitting that multiplicity are the same idea stated twice: the singleton exception is not a concession to redundancy, it is the mechanic.
