Oracle Text

When The Duke of Midrange enters the battlefield, choose one of Thoughtseize, Lightning Bolt, or Abrupt Decay. Cast a copy of the chosen card without paying its mana cost.\nThe Duke of Midrange's power is equal to the number of card types among cards in all graveyards and its toughness is equal to that number plus 1.
