Repo Man

What happens if I use Repo Man (Summons
of the Deep F41) to take control of Infernal
Obsession (Summons of the Deep F51) which
was attached to a character I own?
Repo Man takes control of Infernal
Obsession, which causes that original
character to revert to your control.
Infernal Obsession is now discarded.

FAQ (1.9) [summary]
- attachments do not change control when taking control of character
you cant reattach then when u take control of them
if you take Prize Pistol (IMoD) you can use it, even though the character is not controlled by you

[after card leaves play (goes to discard/hand/etc) it goes to owners discard/etc]

(not important here, for completeness)
- with uniqueness as well, if you have one * character with given name u cant play/take next

- if committed to story character changes side but remains committed

I recently ran this at the local store championship, sadly he failed to live up to my expectations. I still have hope for the ability but icons < skill is never a good sign, especially when the ability is reliant on your opponent having specific cards in play.
