Artefacto
El Bruto de acero oscuro es indestructible. (Los efectos de "destruir" y el daño letal no lo destruyen.)

: El Bruto de acero oscuro se convierte en una criatura artefacto 2/2 hasta el final del 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.
