Artefacto
, descartar una carta arcana o de Espíritu: El Tora adormecido se convierte en una criatura artefacto X/X hasta el final del turno, donde X es el coste de maná convertido de la carta descartada.
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.
