At the beginning of each other players upkeep they may discard each card in their hand.
If they do they must sacrifice all permanents they control. If they do they may put any permanent cards from their graveyard onto the battlefield.
If they don't that player may look at the top card of their library. If they do they may cast that card without paying its mana cost.
If they do you may create a copy of that spell. You may choose new targets for the copy.
