Offspring {4} (You may pay an additional {4} as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.)
When this creature enters, look at the top four cards of your library. You may reveal a noncreature, nonland card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.

Cría {4}.
Cuando esta criatura entre, mira las cuatro primeras cartas de tu biblioteca. Puedes mostrar una carta que no sea tierra ni criatura de entre ellas y ponerla en tu mano. Pon el resto en el fondo de tu biblioteca en un orden aleatorio.
