2 rulings from Wizards of the Coast
- 25 January 2019If a permanent has indestructible, it isn’t destroyed this way and its controller won’t create a Centaur token for it. If it is destroyed but put into a zone other than a graveyard, its controller does create a Centaur token for it.
- 25 January 2019All of the artifacts and enchantments that are destroyed leave the battlefield before any Centaurs are created, and their abilities can’t affect or trigger on these tokens entering the battlefield.
