Yitán, ladrón de Tantalus

If an opponent gains control of Zidane from you, Zidane's last ability will trigger and you'll create a Treasure token. If an opponent gains control of Zidane and one or more other permanents from you simultaneously, Zidane's last ability will trigger for each of those permanents, including itself. This means you'll create a Treasure token for each of those permanents, including Zidane.
