After some discussions with Hobbit_Lad, the text of "Eastemnet Plains" was changed to:
Plains. Fellowship or Regroup: Make the move limit +1 for each culture over 2 you can spot in the fellowship (limit once per turn.)
Otherwise, it would not be very clear, when the bonus was to be applied, as the number of cultures might continually change (new ones played, old ones dying).
I will be updating the text of this card within the next day to reflect this change.
I will also be updating Arrows of Light to add the "(to a minimum of 0") qualifier, correcting the spelling error on Answers in the Fire, and re-wording Crippling Arrows to say, "Until the regroup phase, each wounded minion is prevented from being fierce."
That said, I will have to find alternate hosting for the cards for the time being because Kralik has not been in touch with me for some time. These original images are hosted here on the Wiki, but I have no way of updating them right now because I have no FTP access. I hope to secure some web hosting on Monday and then I will change the image mapping to reflect the new host.
