Memory Leak
Targeted discard usually stops at the hand: Thoughtseize, Duress, and Inquisition of Kozilek all reveal the hand and pull one card before it can be cast. This one widens the search to include the graveyard, which quietly repositions it against a different kind of deck. The reveal-and-strip mode is soft against a live hand (you take one card, they keep casting), but it turns into a scalpel against graveyard-centric strategies, where the card you most want to exile is already sitting in the yard as a reanimation or flashback target. Folding two effects that normally cost separate slots into one sorcery, it functions as discard that can also serve as targeted graveyard hate. Cycling keeps it from being dead weight when neither mode is worth full price. Against a deck with no relevant graveyard and a hand you would rather not spend three mana peeking at, you pay one and draw, treating the card as a filler cantrip instead of a stranded answer. Discard spells that go stale in the wrong matchup are a real cost; here the floor is a replaceable card rather than a wasted draw step. The result is a flexible answer that reads as unassuming at full cost but earns its slot by refusing to ever be a total blank.
