I had a Feral Claws Wolverine team-up selected in “In the Vents”. I then played “An Attempt at Reason”, and although I couldn’t select another Wolverine team-up, the one I already selected was still there, and I used it just to prove I could.
So, with a little planning you can use adamantium slash against Wolverine.
It’s a bug, I guess.
:edit: This occurs only in the new “endless stream of caltrops” mode.
