This has to be a reference to Stephen King's short story "I am the Doorway". I had so many nightmares after readig that, and now it came back haunting me again.
Just some fun with traditional transforming two-faced cards in the middle of this flood of modal two-faced cards. These are some of my old favourite designs. First is top-down desing of a Faerie illusionist. Two others are more Innistrad themed. (Last one is inspired by the brilliant movie: The Thing)
