Conjuro
Gana el control de todas las criaturas que controla el oponente objetivo hasta el final del turno. Endereza esas criaturas. Ganan la habilidad de prisa hasta el final del turno. No puedes atacar a ese jugador este turno. No puedes sacrificar esas criaturas este turno.
You can't sacrifice the creatures you gained control of with Call for Aid this turn for any reason. If an effect instructs you to sacrifice one of them, you can't and it remains on the battlefield. You also can't sacrifice any of them to pay a cost that requires you to sacrifice a creature.
