Play early Spellcasters for payoffs like Dhol Chants, Occult Ritual, and Dream-Quest. Or, just ramp with Cores, Ignis, or extra mana from Sites, to play out big Evil threats. Use Demonic Contract to grab the right threat for any situation, easily meetings its requirements with a variety of Elite/Unique demons, and Coins and Mortals to sacrifice to it to save you the 4 life.
