one generic mana one black mana one red mana Instant

Creatures that come under your control after Showstopper resolves won’t have the ability.

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.
