Eater of Virtue

The wearer inherits the graveyard. Most Equipment cares only about the creature currently holding it; this one exiles every creature that dies wearing it and keeps a running ledger of their keywords, so the +2/+0 body accumulates flying, first strike, deathtouch, and the rest as the sword's own attached creatures fall. That inversion is the design idea: a sacrifice outlet's worth of dead bodies becomes an ability suite that outlives all of them. The stronger the creature you feed it, the more the next holder wears, and because the exile is mandatory on death, the sword actively wants its bearer to die and be replaced. It rewards a churn of expendable, keyword-rich creatures rather than one prized target, which flips the usual Equipment calculus of protecting your best body: here the best body is the one you are willing to lose so the sword can strip it. The cheap cost to cast and equip keeps the whole loop fast enough that the accumulation matters within a single game rather than as a slow grind. What it collects is exactly the thirteen evergreen combat and protection keywords it names, no more; anything beyond that list stays behind with the corpse. Read that way, it is less a weapon than a reliquary, banking the martial virtues of the fallen and handing them to whoever picks it up next.
