Reminisce

The whole spell turns on a single decision: whose graveyard. Pointed at yourself, it answers an era's anxiety about an exhausted library, shuffling your bin back into your deck so you keep drawing, a sorcery-speed undo for a deck running on empty or anti-mill insurance against a clock about to deck you out. Pointed at an opponent, it scrambles the graveyard they spent the game assembling back into their library, stripping flashback fodder, threshold counts, and reanimation targets, though at the price of refilling a depleted deck (so you aim it at the player who minds losing the payoffs more than they need the cards back). There is no symmetric line where it strictly helps you; every cast is a wager that one player wants the refill and the other wants the denial, and you are choosing which. It comes from a graveyard-conscious moment, when threshold and similar mechanics rewarded players for filling and reading their bins, so a spell that scoops the entire pile back into the deck reads as a deliberate counter-lever to that design. The rate is plain and the application narrow, which has kept it on the margins of competitive play. But the idea (one spell that is salvation or sabotage depending on whose graveyard you choose, and which need is more pressing in the moment) carries more strategic weight than the single line of text lets on.
