Remake the Universe

Convoke, improvise
This spell can't be countered.
Exile your graveyard and all cards in your hand and
each permanent you control. Draw five cards then
reveal X cards from the top of your library, where
X is the number of cards exiled this way. Then you
may put all permanent cards revealed this way onto
the battlefield and may play any nonpermanent cards
revealed this way until the end of their next turn.
Each opponent copies this spell.
