Eternal Torment

Starting with you, each player may discard any
number of cards and deal that much damage
to the player to their right.
Then, starting with the player to your left, each
player may exile any number of creature cards
from their graveyard. For each card exiled this
way, that player loses 1 life and exiles the top
card of their library. Each player may cast spells
and play lands exiled this way until the end of
their next turn
