Mimeofacture

Steal-by-name is the wrinkle here, and it changes what theft costs. Most blue snatch effects take the permanent you can see and pay for it directly. This one goes after the library instead, demanding the targeted opponent has a second copy of the named permanent buried in their deck, then putting that duplicate onto the battlefield under your control while the original sits untouched on their side. It is a one-for-one in cards (your spell for their buried copy), but it works only against redundancy: point it at a singleton legend or a one-of answer and it whiffs outright, because there is no twin to find. Against a deck running multiples it peels a fresh threat off the top of their list, and that dependence on what an opponent chose to register is the price for the upside. Replicate is the lever that turns the gamble into a haymaker: each extra payment of the cost copies the spell, so paying twice lets you point copies at two different permanents and rip two duplicates from a library that has them to spare. The card belongs to a brief strain of library-interactive theft that asks you to read an opponent's decklist as a resource pool rather than their board as a target, a design axis the game has rarely revisited precisely because it lives or dies on whether the table is running copies.
