Gilded Pinions

Half the price comes back the instant the artifact resolves. The Treasure minted on entry means casting this for two mana leaves you with any-color fixing regardless of whether you ever attach the Equipment, so the card front-loads its value into the enters trigger rather than the equip rate. That decoupling is the whole point: on a turn with nothing worth suiting up, you cast it, bank the single-use fixing, and hold the sorcery-speed equip for a threat that actually wants flying. Grant-flying Equipment is a crowded shelf, and most entries compete on how cheap the equip is or on a second stapled keyword. This one competes on the accounting. Flying alone is a modest thing to hand out, and the equip cost is unremarkable, so the design pays for itself before you decide what to do with it: worst case, two mana buys you a color-fixing Treasure that happens to leave an Equipment on the battlefield afterward. The ceiling is low, one evasive attacker at a time with movement locked to sorcery speed, but the floor sits higher than most two-mana artifacts because the Treasure guarantees the card does something useful in the games where nobody ever gets suited up. It is a design that trades a splashy payoff for a refusal to be dead in your hand.
