A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Here, there was a ruling that the "other ruling" was reversed, but the link in the OP's post links to a thread wherein the ruling lists itself as a reversal as well.
Coming back to the thread I linked above, is the ruling confirming that the Egg of P'an Ku can copy Matsu Nimuro xp2's ability or is it a reversal stating that it cannot do so?
