Thanos' Snap

Each player loses half their life, then discards
half the cards in their hand, then puts half of
their library and graveyard into exile, then puts
half of their nonland permanents into exile.
Round up each time. Then deal 10 damage
to each opponent.
"With all six Stones, I could simply snap my
fingers. They would all cease to exist. I call that
mercy."
—Thanos
