Shattered Veil

Whenever you cast a Sorcery or Instant spell, Shattered Veil deals 1 damage to random target creature or player.
At the beginning of your upkeep, if you control
no permanents other than Shattered Veil and
have no cards in hand, you win the game.
This world is a prison. And I will set as all... free.
