One ruling from Wizards of the Coast
- 1 September 2023You don't choose a target for Talion's Messenger's ability at the time it triggers. Rather, a second "reflexive" ability triggers when you discard a card this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
