Magecraft— Whenever you cast or copy an
instant or sorcery spell, each opponent mills
two cards.
{2}{u}{u}{b}, {t}: Exile target instant or sorcery card
from an opponent's graveyard. Copy that card.
You may cast that copy without paying its
mana cost.
"The work of the many is the benefit
of the few."
