Graveyards are usually where lands go to be forgotten. This colorless three-mana rock treats them as an open toolbox, borrowing every activated ability printed on every land card sitting in any graveyard, yours or an opponent's. The framing inverts the usual relationship between a permanent and its abilities: the source stays dead in the yard while this artifact wears the ability on the battlefield. A milled manland, a discarded creature land, a fetchland someone cracked three turns ago: their activation costs and outputs all become available through this single object, and they keep working even as the contents of the graveyards shift underneath. The wrinkle worth understanding is what "self-reference" means once an ability changes homes. When this artifact gains an ability that reads "Tap, Sacrifice this land," the object being sacrificed is the artifact itself under the rules, not the card in the graveyard: it pays by feeding itself into the cost, exactly as the granted ability's controller would expect. That makes the borrowing more literal than it first looks, and it is the artifact, not the corpse in the bin, that lives or dies by these activations. The design invites building a graveyard worth mining rather than a board worth protecting, and it rewards self-mill and land-dense yards over the creature recursion those strategies usually chase. Its indifference to ownership is the price: with no land cards in any graveyard it produces nothing, and it will just as happily lend you an opponent's discarded land as your own seeded ones.
