The Cosmic Horror

This Role is Hidden. (Show it to no one.)
During your turn you may pay {10} and reveal
your Role. If you do, for each player you create a
5/5 black Horror creature token with "When this
creature attacks, the defending player mills 10."
Win: You win the game when two players have
lost due to having no cards in their deck. If
another player would win from this, they do not.
