Evershrike's Gift

Most Auras carry a built-in tax: they die with the creature they enchant, so a cheap buff can never really run away with a game. Recursion is one way around that, but the version here refuses to let recursion come cheap. Casting it costs a single white mana; the loop back from the graveyard costs and carries blight 2, so every return demands you seed a friendly body with two -1/-1 counters. The engine feeds on itself by design: you shrink a creature you already control, potentially to nothing, in order to hand fresh evasion to another. That self-inflicted damage is what lets the rebuy exist at all without the Aura spiraling. The sorcery-speed clause on the return closes off any end-step surprise and forces the decision into a deliberate main phase. Where the card earns its slot is a shell built to profit from its own board withering: counter-matters payoffs that treat those -1/-1 counters as fuel, aristocrat engines that would rather sacrifice a dwindling creature than watch it dwindle further, or a board wide enough that trading a body's toughness for repeatable flight elsewhere is a fair rate. The +1/+0 and flying are almost beside the point; the interesting truth is that this Aura wants to die and keep coming back, dragging your board down a notch on every trip home.
