Nonland cards in your hand have upgrade. Their upgrade cost is {2}{u}{b}.({2}{u}{b}, Discard that card: Search your library for a card with converted mana
cost equal to that card's converted mana cost plus 1
and put it in your hand. Then shuffle your library.)
Instant and sorcery spells you cast cost {1} less to
cast for each time you've searched your library
this turn.
