Eldritch Moon — Uncommon
Creature — Human Horror
When Foul Emissary enters the battlefield, look at the top four cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
When you sacrifice Foul Emissary while casting a spell with emerge, put a 3/2 colorless Eldrazi Horror creature token onto the battlefield.
