Nearly every graveyard payoff rewards filling the yard; this one waits for cards to leave it. That reversal is what defines the build. It watches for the moment artifacts and creatures exit your graveyard during your turn, which reframes a resource most decks treat as a dumping ground into something you want to actively empty. Reanimation spells, artifact recursion, and any effect that pulls the yard back on your own clock all become growth engines. The trigger fires once per event, not once per card: an ability that returns three creatures at once still yields a single +1/+1 counter, so the multiplier comes from stacking separate recursion effects across a turn, not from mass returns. That distinction shapes the deck. A build that loops one small artifact or dork repeatedly gets more mileage than one that dumps its whole graveyard back in a single spell. The counter is permanent rather than a temporary pump, so the growth compounds turn over turn. The enchantment does nothing on an empty graveyard and nothing on an opponent's turn, so it lives entirely inside a shell designed to recur its own components on its own timeline. It sits in the black recursion space as a quiet enabler for decks that want their bodies to fatten every time the yard gives something back, and the two-mana price keeps it cheap enough to land the turn before the recursion engine comes online.
