2 rulings from Wizards of the Coast
- 19 January 2018While Baffling End’s two abilities are flavorfully related, they are independent. If the first ability doesn’t resolve (perhaps because the target gained hexproof), the second will still create a Dinosaur token when Baffling End leaves the battlefield.
- 19 January 2018In a multiplayer game, the target opponent who creates a Dinosaur token doesn’t have to be the same one whose creature was exiled.
