I recently played a story mission with Kyra and Merisiel where Ghlorofaex was the villain (not sure which mission). After one of my fights against him, he moved into Kyra's hand. Now, he is permanently stuck in her deck. I can discard him for damage, but otherwise have a useless card clogging up my deck. Is there some way I can remove him? (I haven't been lucky enough to have him in my hand for a banish a card scenario yet.)
