Let's Keep a Little Optimism

While you control a Legendary creature and an opponent did not attack you with any creatures
during that opponent's previous turn, that same opponent's spells may not deal damage to your creatures and that opponent may not cause your
Life total to be reduced. At any time you may
exile Let's Keep a Little Optimism to take the top
card of your graveyard into your hand.
"Where there is life, there is hope."
