Lucent Awakening

You play with your hand and the top card of
your library revealed.
At the beginning of each opponent's upkeep,
that player chooses either a nonland card in your
hand or the top card of your library. Until end
of turn, you may cast that card without paying its
mana cost and as though it had flash. If you cast
a spell this way, you lose life equal to its mana
value. Then each player draws a card.
