Spontanzauber
Bis zum Ende des Zuges erhalten Kreaturen, die du kontrollierst, „Wenn diese Kreatur stirbt, fügt sie einer Kreatur deiner Wahl, die ein Gegner kontrolliert, 2 Schadenspunkte zu."
If another player gains control of a creature you control after Showstopper resolves, and then later that turn that creature dies, the creature’s controller when it died controls the triggered ability. That player chooses a creature that one of their opponents controls as a target.
