Encantamiento
Siempre que lances un hechizo que solo haga objetivo a un único artefacto o criatura que controlas, crea una ficha que es una copia de ese artefacto o criatura, excepto que no es legendaria.
The triggered ability of Vesuvan Duplimancy triggers only if you cast a spell that targets a single artifact or a single creature and nothing else. The ability will resolve before the spell that caused it to trigger, and a token will be created even if the spell you cast was countered or permanent it was targeting is now an illegal target.
