Old One's Return

If a player would lose the game this turn, instead
their life total becomes 15. That player shuffles
their hand and graveyard into their library, then reveals cards from the top of their library until a
number of land cards equal to the number of
lands you control are revealed. Put those
permanents onto the battlefield. Repeat this
effect for enchantments, artifacts, and creatures,
then that player shuffles their library and draws
three cards.
