Demonstration of the Gods

Destroy all lands. All players discard their hand
and then exile half of their permanents rounded
up.
Act of Gods —All cards exiled this way are exiled
with 3 Heavenbound counters on them, at the beginning of each players upkeep, remove one Heavenbound counter from each creature
they control in exile, and if a creature has no
more Heavenbound counters on them, put that creature into the graveyard from exile.
