I haven't played for a while since the 2 recent updates and I fired up the game to try out the new missions. I used my "Police & Thief" deck and surprise surprise... Lanz has been nerfed! His bonus to other Thieves are only given when he scores. His threat ability is still powerful but his overall power level has dropped.
It'll be interesting to find other balance changes, although an official announcement on all the errata would have been cool. I don't think I'll be updating my screenshots of the cards but may do a post on all the changes as I have the old Templar screenshots to compare.
