Shared Fate

If a player would draw a card, that player exiles the top card of one of their opponents' libraries face down instead.
Each player may look at cards they exiled with Shared Fate, and they may play lands and cast spells from among those cards.

The List

Mirrodin

If a player would draw a card, that player removes the top card of an opponent's library from the game face down instead.
Each player may look at and play cards he or she removed from the game with Shared Fate as though they were in his or her hand.

If more than one Shared Fate is on the battlefield, you choose which one replaces each card draw, but you can replace a draw only once.

Replacing your draws isn't optional. You can't draw cards from your own library, even if all your opponents' libraries are empty.

The cards are exiled, not put onto the players' hands. Players can look at and play the exiled cards, but can't do anything else with them (the exiled cards can't be discarded or cycled, for example).

You need to pay the costs of any cards you play from the Exile zone. This could be a problem if you don't have the right colors of mana available.

Each Shared Fate tracks only the cards it exiled. If the Shared Fate which was responsible for a card being exiled leaves the battlefield, putting another Shared Fate onto the battlefield will not allow you to play that card again.
