rules.l5r.com has now been updated with the post-Samurai Edition rules for the Legacy format. I haven't finished making it "pretty" yet, but it is there if you want to review it before GenCon if you plan to play in the Legacy format event.
Thanks!
Legacy Rules Update
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.
