I am also experiencing this bug with Succubus on the Xboxone, post patch. Can not place on opposing rows except for melee, works fine on my own, haven't had issues with any other disloyal cards yet. Submitted a bug report already, but posting here to get more eyes on this problem. I'm relatively new and free to play with a limited collection. I play monsters 99% of the time as that's where I crafted cards and it's what I want to play. Succubus is a cornerstone of these decks and this bug is a huge barrier to my ability to compete. If something like this happened after the official release I would consider leaving the game if it took too long to resolve and would certainly expect some form of compensation, or in the least, an official apology. As it is beta, I'll attempt to remain calm, and expect nothing other than the problem to be addressed swiftly, but again, I point out how strongly this is impacting my ability to play and enjoy the game.
