Nykthos, Shrine to Nyx Nykthos is a legendary land that taps for colorless mana, but you can also tap it and pay mana to add mana to your pool for each devotion you have to a single color

Continuing the horror theme are cards reimagined in the style of comic-book front covers for Creepshow, the cult 80s movie heavily inspired by fifties comics like Tales from the Crypt
