Lost to Legend

The tuck is the whole trick. Destroying a permanent hands it to the graveyard, where reanimation and recursion can fetch it back; white's own exile removal invites answers too, since exile-hate is live counterplay. Slotting the target four cards deep into its owner's library does something quieter: it strands the threat behind three draws, buys most of a game-cycle before it can be redrawn and recast, and, crucially, leaves the target's controller no reusable answer. It sits in white's relocation lineage, the same design instinct behind Condemn, which drops an attacker to the bottom of the deck, and Oust, which pushes a creature second from the top: relocation rather than annihilation, but here pointed at durable centerpieces rather than a swinging body. The target restriction is what pays for a two-mana instant this flexible: only nonland historic permanents, so artifacts, legendaries, and Sagas are fair game while an ordinary vanilla creature stays untouchable. That narrowing aims the card at the pieces most likely to be worth answering: the engine artifact, the value legend, the ticking Saga. Note the honest limits. The permanent never reaches the graveyard, so death triggers stay dormant, but any leaves-the-battlefield trigger still fires as it goes. And a commander need not take the long swim through the deck: its controller may send it to the command zone instead, which reduces the tuck to a tempo tax rather than a true removal. The relocation is temporary by design; the tempo it buys is the point.
