Spontanzauber
Bringe einen X/X schwarzen Schrecken-Kreaturenspielstein ins Spiel, wobei X gleich der Anzahl an Kreaturen ist, die in diesem Zug gestorben sind.
Use the number of creatures that died that turn as Spoils of Blood resolves to determine the value of X. In other words, creatures that die in response to Spoils of Blood will count.
