Resentful Revelation
Dig three, keep one, bin the other two: a black self-mill smoothing effect at two mana, given a second life from the graveyard. This is card selection wearing the costume of card advantage. You net no cards, since the spell only replaces itself, but the pair you leave behind aren't spent so much as relocated: they go straight from library to graveyard, seeding the bin for whatever else your deck wants to do with a stocked yard, and the flashback clause lets the spell itself become one of those payoffs. The return cost is what you pay for repeatable selection; it turns a cheap early filter into a late-game topper you already own, so the same slot that steadied your opening hand refills it once your mana is flush. The design lives on that split personality: early, a tool for finding the right card while feeding the graveyard; late, a spell you cast twice from two zones without spending a draw step. The friction is that keeping one card means committing the other two to the bin. You look at three, you take one, and the two you pass over get pitched. That surrender of choice buys the low front-end cost, and it steers the card toward decks that are indifferent about which cards end up in the bin, or actively glad they're there. It is a filter for players who have already decided the graveyard is an asset rather than a loss.
