Whenever you cast an instant or sorcery spell,
scry 2.
{2}{u}, {t}: Look at the top X cards of your library,
where X is the number of instant or sorcery cards
in your graveyard. You may reveal an instant or
sorcery card from among them and cast it without
paying its mana cost. Put the rest of the revealed
cards on the bottom of your library in any order.
