Whenever a spell or ability you control would
make you discard a card, you may Foretell that
card instead. Its foretell cost is equal to its mana
cost minus {2}. (Exile it face down. Cast it on a
later turn for its foretell cost.)
{1}{u/b}{u/b}, {t}, Discard a nonland card with mana
value X: Search your library for a card with
mana value X, Foretell that card, then shuffle.
