Soldevi Digger
An anti-mill artifact from an era that took graveyard depletion seriously as a clock. The whole design exists to answer a single threat vector: the dedicated library-into-graveyard strategies that floated around the mid-90s, where the win condition was running an opponent out of cards rather than out of life. Each activation recycles a graveyard card back into the deck, paying mana to refill the library and keep it from emptying. The friction is built into the rate: it pulls only your topmost graveyard card, so you cannot cherry-pick which one to save, and it costs mana every time, meaning a fast mill clock will usually outpace what you can repurchase. That makes it a hedge, not a hard lock. The card is interesting less for what it does than for what its existence implies: that "deck out" was a real enough plan in this period to warrant a colorless, anyone-can-run-it artifact dedicated to surviving it. As mill receded from competitive relevance, so did the demand for a stapled-in deck-recycling answer, and Soldevi Digger settled into the long tail of artifacts that solved a problem the format eventually stopped having.
