Rulings
- Playing a card exiled with Fiend of the Shadows follows all the normal rules for playing that card. You must pay its costs, and you must follow all timing restrictions, for example.
- You may only play the card, meaning play it as a land or cast it as a spell. It's not in your hand. You can't discard it, activate its cycling abilities, and so on.
- As long as the card remains exiled, you may still play it, even if Fiend of the Shadows leaves the battlefield or changes controllers.
- If this creature deals combat damage to multiple players simultaneously, perhaps because some combat damage was redirected, its ability will trigger for each of those players.
