Old rule (Future Sight) New rule (Core Set - Tenth Edition)

506.3.

To start the subgame, each player removes his or her library from the game face down. It becomes that player's deck in the subgame. Abilities that trigger on cards being removed from the main game face down will trigger.

506.2.

As the subgame starts, an entirely new set of game zones is created. Each player takes all the cards in his or her main-game library, moves them to his or her subgame library, and shuffles them. No other cards in a main-game zone are moved to their corresponding subgame zone. Randomly determine which player goes first. The subgame proceeds like a normal game, following all other rules in section 101, "Starting the Game."
