At the beginning of your upkeep, flip a coin. If you win the flip, look at the top three cards of your library, then put them back in any order.
You may shuffle your library. Draw a card. If it is an artifact card, you may cast it without paying its mana cost.
If you lose the flip, put the top two cards of your library into your graveyard. You lose 2 life.
