Just curious on this since I didn't follow the AG threads at the time. Was the reason for the change in AG after you got the original email response ever clarified, or are we assuming that it was for balance reasons.
I ask is because that email response you received seemed arbitrary to me. There is nothing contradictory about both cards having their full effect, including the restrictions. Basically the current ruling seems more consistent with the RAW.
If you can point me to a thread so I can educate myself, I'd prefer not to have this thread not go down that tangent.
