Sevinne's Reclamation

The self-reference is the entire payoff. Reanimating a permanent with mana value three or less is a fair enough white effect on its own: mana dorks, small enchantments, cheap artifacts, a value creature or two. But the copy clause only fires when the spell is cast from the graveyard, which is precisely what flashback lets you do. Cast it from hand and it is a single, honest reanimation. Send it to the bin first (resolved from hand, discarded, milled), then flashback it, and you reclaim two permanents off one card, the second target chosen fresh. White rarely gets to loop like this, and the design routes the payoff through the least glamorous path: the sorcery has to reach the graveyard before it pays off, so the reward goes to decks patient enough to treat their own bin as a staging area rather than a dumping ground. The three-or-less ceiling keeps the returns modest by rate, which is what the doubling is allowed to bend; two small permanents at a time reads very differently from two of anything. White recursion has always been narrow and one-shot, the effect that brings a single small thing back and is then spent, and the flashback exile clause is what caps this version too: the second cast eats the card. You get the double, once, and then the reclamation is gone.
