At the beginning of your upkeep, choose target creature an opponent controls. That creature's controller may sacrifice it. If they don't, create a
token that's a copy of that creature, except it's an artifact in addition to its other types.
"The choice is yours, darling. Your life can end now, or you can ensure your legacy lives on forever. And there's no shame in this process. After all, you're only the prototype."
