2 rulings from Wizards of the Coast
- 1 June 2011If this spell doesn't resolve, none of its effects occur. In particular, it will go to the graveyard rather than to its owner's library.
- 16 March 2018Because you follow the spell's instructions in order, you won't be able to draw the same Blue Sun's Zenith that you cast.
