Diligent or Distracted Study

Reveal the top five cards of your library, then exile them in a face-down pile. At the beginning of your next turn, an opponent chooses a number between 1 and 5, then you name a card. Turn the top X cards of the exiled pile face up, where X is the chosen number. If the named card is the last card revealed this way, put the exiled cards into your hand. Otherwise, put the exiled cards on the bottom of you library in any order, then draw three cards.{/fontsize-8}
