Aegis Angel

Vuela. Cuando el Ángel de la égida entre al campo de batalla, otro permanente objetivo es indestructible mientras controles el Ángel de la égida. (Los efectos que dicen "destruye" no destruyen ese permanente. Una criatura indestructible no puede ser destruida por daño.)

Flying (This creature can't be blocked except by creatures with flying or reach.) When this creature enters, another target permanent gains indestructible for as long as you control this creature. (Effects that say "destroy" don't destroy it. A creature with indestructible can't be destroyed by damage.)
