MAGIC: THE GATHERING
|Edition:||Guilds of Ravnica|
Surveil 2, then choose an instant or sorcery card in your graveyard. You may cast that card this turn. If that card would be put into your graveyard this turn, exile it instead. (To surveil 2, look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)
In controlling, removal-heavy decks, Mission Briefing is pure value. Don't forget that it has Surveil 2 - if you don't have any good spells to cast in your graveyard, you may be able to find one on top of your library!
