1/22/2011 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.
1/22/2011 As long as the card remains exiled, you may still play it, even if Fiend of the Shadows leaves the battlefield or changes controllers.
1/22/2011 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.
