Dead Man's Chest

A theft Aura wearing the silhouette of a kill spell, and that disguise is the whole tension. It produces nothing until the enchanted creature dies, which is why the cleanest line is often the most direct: cast it on a threat, then point your own removal at that same threat and collect the payoff yourself. The card does not kill for you, but it converts a death you were already going to arrange into a heist. The reward scales to the dead creature's power, so the instinct is to enchant the biggest body on the table, and that instinct fights the clock: a high-power creature is usually one your opponent intends to attack with, so you either wait for combat to resolve it or spend a resource forcing the issue. When it cashes out, the steal is unusually permissive: the exiled cards stay castable indefinitely and any type of mana pays for them, sidestepping the color-fixing problem that has always made library theft awkward to convert into actual spells. That generosity gives it a different character from a one-shot impulse-draw effect; it functions more like a slow lien on an opponent's deck, harvesting whatever happened to sit on top when the body finally fell. The friction is that everything routes through a death, which rewards decks that already manufacture kills over decks hoping the game supplies one.
