2 rulings from Wizards of the Coast
- 13 July 2018If the target creature is an illegal target by the time Transmogrifying Wand’s ability tries to resolve, the ability doesn’t resolve. No player creates an Ox token.
- 13 July 2018If the target creature is a legal target but can’t be destroyed, most likely because it has indestructible, its controller gets an Ox token and gets to keep that creature.
