Showstopper 


Instant
Until end of turn, creatures you control gain "When this creature dies, it deals 2 damage to target creature an opponent controls."
The audience quickly realized a few things: it wasn't a magic trick, there wasn't candy in there, and they'd need new clothes.

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.
