My opponent has a Shalai, voice of plenty on the field That I need to remove. I cast Bishop of Binding with a Panharmonicon on my side. Do I target the angel for both triggers as she's the only option or can the second trigger, given by Panharmonicon, target something else once Shalai is out of the way?
You have to target Shalai as the target is named when the ability triggers and at that time all your opponents creatures will have hexproof and cannot be targetted.
