Each player chooses a nonland permanent they control. Return all nonland permanents not chosen this way to their owners' hands. Then you draw a card for each opponent who has more cards in their hand than you.
Starting with the player whose turn it is, each player chooses a nonland permanent they control. Players get to know what permanents have been chose by players that chose before them as they make their choice. Then all nonland permanents that weren't chosen by any player are returned to their owners' hands at the same time.
