Aurification

Punishment dressed as defense. Most pillowfort enchantments stop attackers before they connect; this one waits until a creature has already hit you, then converts the aggressor into a permanent liability for its controller. The gold counter rewrites the offending creature into a Wall with defender, so the very thing that swung at you becomes a blocker stuck on the opponent's side of the board, contributing nothing to their clock. Against an opponent who commits the team, the effect compounds: every connecting attacker gets gilded in turn, and a board built for tempo slowly inverts into a row of immobilized statues. The leave-the-battlefield clause is the genuine wrinkle, and it cuts the other way. Removing all gold counters when the enchantment dies is a liability for you, not a tool: bounce it, sacrifice it, or let it get destroyed and every gilded blocker snaps back to attacking shape at once, handing the opponent an army they thought was neutralized. That makes the card uniquely punishing to lose once it has been doing work, which inverts how most enchantments degrade. The deeper tension is the trigger condition itself: it only ever pays off after you have already taken damage, a strange demand from a card whose job is keeping you alive, and against an opponent content to sit back it never fires at all. The flavor (King Midas turning his foes to gold) and the function (you must bleed before it rewards you) is what keeps it a strange one rather than a staple.
