As Story Circle enters the battlefield, choose a color.
: The next time a source of your choice of the chosen color would deal damage to you this turn, prevent that damage.
At the beginning of each player's draw step, that player puts the cards in their hand on the bottom of their library in any order, then draws that many cards.
Exile all nontoken permanents. Starting with you, each player chooses one of the exiled cards and puts it onto the battlefield tapped under their control. Repeat this process until all cards exiled this way have been chosen.
