Liwl, Thunderous Hunger

At the beginning of your end step, you may
sacrifice permanent. If you do, each opponent
may sacrifice a permanent that shares a card type
with it. For each opponent who doesn't, that
Liwl, Thunderous Hunger deals 3 damage to
that player and you draw a card.
{t}: Exile a target card from an opponents
graveyard. You may cast that card until the
beginning of the next upkeep.
