Remake the Universe

Split second

Players can't lose or win the game until end of turn. Put
all cards in each player's hand and graveyard and each
permanent on the bottom of its owner's library. Each
player draws seven cards, then exiles the top ten cards of
their library. Put each land card exiled this way onto the
battlefield under its owner's control. Players may cast any
number of nonland cards they own exiled this way
without paying their mana cost until the end of your next
turn.
