Mirrored Reality

When Mirrored Reality enters the battlefield, put the top 5 cards of your library out of the game.
If you would draw a card, put a card face down with the other cards removed from the game.
At your upkeep, you may replace your hand with the face down cards.
When playing with your second hand, do not use creatures from your normal hand.
When playing your second hand, keep a different life total.
