Artefatto

, Scarta una carta Spirito o Arcano: La Tora Dormiente diventa una creatura artefatto X/X fino alla fine del turno, dove X è pari al costo di mana della carta scartata.
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.
