Conjuro
Victimizar 3. (Al lanzar este hechizo, puedes sacrificar una criatura con fuerza de 3 o más. Cuando lo hagas, copia este hechizo y puedes elegir un nuevo objetivo para la copia.)
Exilia la carta de instantáneo o de conjuro objetivo del cementerio de un oponente. Copia esa carta. Puedes lanzar la copia sin pagar su coste de maná.
After Flawless Forgery resolves, the exiled card remains exiled.
Casualty N means “As an additional cost to cast this spell, you may sacrifice a creature with power N or greater.” and “When you cast this spell, if a casualty cost was paid for it, copy it. If the spell has any targets, you may choose new targets for the copy.”
If you pay the casualty cost of a spell, the copy will resolve before the original spell.
The copy of the spell is created on the stack, so it's not “cast.” Abilities that trigger when a player casts a spell won't trigger.
You may sacrifice only one creature to pay a spell's casualty cost, and you copy the spell only once.
