Unveiling the Book Chamber

Epiphany — At the beginning of your upkeep on
your first turn, if Unveiling the Book Chamber is in
your starting hand, you may discard it. If you do,
reveal cards from the top of your library until you
reveal a basic land card. Put that card into your
hand and the rest on the bottom of your library
in a random order.
Draw a card.
The mere presence of knowledge means power.
