: La Llave rúnica gruul se convierte en una criatura artefacto Bestia roja y verde 3/2 con la habilidad de arrollar hasta el final del turno.
 
Activating the ability that turns the Keyrune into a creature while it's already a creature will override any effects that set its power and/or toughness to another number, but effects that modify power and/or toughness without directly setting them will still apply.
 
Until the ability that turns the Keyrune into a creature resolves, the Keyrune is colorless.
