Artefato
Bruto de Aço Negro é indestrutível. (Nem os efeitos que "Destroem" nem o dano letal o destroem.)

: Bruto de Aço Negro torna-se uma criatura artefato 2/2 até o final do turno.
A noncreature permanent that turns into a creature can attack, and its
abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn’t matter how long the permanent has been a creature.
