Soul Separator

Dismemberment rendered as design: take one dead creature and split it into its two component parts. The Zombie inherits the body (a black token with the dead creature's exact power and toughness, a pile of stats and nothing else), while the Spirit inherits the soul (a flying 1/1 that carries the entire text box, every triggered and static ability, stripped of the stats that made it a threat). One graveyard creature becomes a beater and a flier with the same rules text, and the interesting decision is which half you actually wanted. There is no timing restriction on the activation, so the whole split can resolve at instant speed. What holds it in check is the price rather than any sorcery clause: five mana on top of the tap, plus sacrificing the artifact itself, buys exactly one separation before the thing is gone. That single-use, high-investment structure steers the card toward reanimation targets whose value lives in the text box rather than the body: a tapper, a sacrifice engine, a creature whose enters-the-battlefield effect or static ability does its work regardless of whether a 1/1 can trade in combat. Feed it something whose whole point was its stats and you have wasted most of the effect on a flier that cannot fight. Soul Separator converts "what made this creature good" into a literal fork with two token answers.
