2 rulings from Wizards of the Coast
- 3 May 2019If the target permanent or player is an illegal target by the time Ral’s Outburst tries to resolve, the spell doesn’t resolve. You won’t look at the top two cards of your library.
- 3 May 2019If you have only one card in your library, you put it into your hand. You won’t lose the game if your library’s empty until you try to draw from the empty library.
