Ok so I was playing FoS and I ended up getting a Lost and Alone so I shuffled Frodo in my deck. Then a Nameless thing came out and I engaged it and I attached the 3 cards to it and one of the cards was Frodo. What do I do? Do I get Frodo back now and then replaced frodo with another card? Do I Put frodo in the discard pile and then replaced him with another card? Do I not replace him but what would his cost be?
