Liliana's Spoils
The discard half is the obvious value, but the digging behind it is where the design work sits. Stapling forced discard to card selection sounds generous until you read the fine print: the second half only finds black cards, and everything you pass on gets shuffled to the bottom rather than staying on top. That restriction to a single color is the whole cost of the bundle. You are not scrying or stacking; you are committing to a single five-card peek that can whiff entirely if the top cards are colorless or off-color, and you scramble your library position either way. The card wants a deck black enough that a look at five almost always surfaces something worth taking, which is the tax on bundling two effects into one sorcery. Think of it as a discard spell welded to an Impulse-style dig walled off to a single color, sold as a play that does both at reduced efficiency. The discard does not let you choose the card that leaves the opponent's hand, and the selection lets you keep only one of the five, so neither half is best-in-class; the appeal is the pairing, and the pairing only works for a deck already committed hard to black.
