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.
So the following promos are not legal due to availability at this year's GenCon according to the AEG website:
Ayamari Clan Banner Strict Training Sushi Stand Tsukotu Unexpected Resistance
Is it a mistake or can I still use Clan Standard at GenCon this year?
