Denethor the Mad Seer

At the beginning of your upkeep, each opponent
loses X life and you scry X, where X is how many
times you have been Tempted by the Ring.

{2}{b}{u}: Reveal the top card of your library. If it is
an Instant or Sorcery, you may cast that card
without paying its mana cost. Otherwise you draw
that card and The Ring Tempts you.

When Denethor dies, discard your hand and draw 1.
