The Snap

Flash
Each player has half of their permanents, half
the cards in their hand (rounded up) and the
top half of their library (rounded up) removed
from the game. You choose what permanents
on the battlefield and cards in all players' hands
are removed from the game. All the cards
removed from the game cannot be brought back
except by a sorcery card named The Blip.
