Jirin, Azorius Adjudicator

Vigilance
Whenever Jirin, Azorius Justiciar attacks, detain target creature defending player controls. (Until your next turn, that creature can't attack or block and its activated abilities can't be activated.)
"Your sniveling and whining mean nothing to me.
Come quietly, and I guarantee you a fair trial. Or I could leave you here. I'm sure the Boros won't be as forgiving."
