Shared Fate — ruling 1

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.

Shared Fate — ruling 2

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.

Shared Fate — ruling 3

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

Shared Fate — ruling 4

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.

Shared Fate — ruling 5

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).

Shared Fate : règles, fonctionnement et interactions (MTG)

Shared Fate is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

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 this enchantment, and they may play lands and cast spells from among those cards.
