Mithra the Thunder Vassal và Escher the Frost Vassal đang ngửa trên sân của tôi. Trong trường hợp này, trong Main Phase của đối thủ, nếu tôi kích hoạt Hiệu ứng nhanh của Ehther the Heavenly Monarch , nhưng đối thủ của tôi lại kích hoạt Compulsory Evacuation Device và trả Escher the Frost Vassal lên tay tôi, thì hiệu ứng của Ehther the Heavenly Monarch thực thi như thế nào?
