What does Hallowed Moonlight actually exile?
This is a good response to, say, flicker effects. If a player wants to make creatures go to exile and come back to get enters-the-battlefield triggers again, you can cast this so that they don't get them at all! Hah! This also applies to tokens, of course, along with Put a...onto the battlefield effects, meld... The list goes on. This is a fantastic card.
