If False Prophet (and the rest of the creatures on the battlefield) are destroyed by a board wipe such as Wrath of God or Nevinyrral's Disk does False Prophet's ability trigger before the other creatures hit the graveyard thereby removing them from the game?
Everything dies at the same time and False Prophet's trigger will go onto the stack after everything dies. The only way for its trigger to actually exile anything in this case is if something died and returned (undying) or created a token when it died. And even then, it depends on whose turn it is to determine which trigger resolves first.
