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.

Now that appropriate materials have been recieved,
With regards to this post, http://www.alderac.com/forum/viewtopic.php?f=59&t=59957&p=769720&hilit=Togashi+Hoshi#p769720
Will my copies of "Hoshi Masujiro" and "The Wrath of Osano-Wo" be considered official proxies of the cards "Togashi Masujiro" and "Wrath of Osano-Wo", respectively, for samurai legal deck construction?

They're not proxies, they're previous printings. Previous printings are always legal.
