2 rulings from Wizards of the Coast
- 22 September 2011Lost in the Mist targets both the spell and the permanent. You can only cast it if you can choose legal targets for both parts.
- 22 September 2011If one of Lost in the Mist’s targets is illegal by the time it resolves, Lost in the Mist will still affect the remaining legal target. If both targets are illegal at this time, Lost in the Mist won’t resolve.
