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.
A player, 13 October 2011
Card: Temples of Gisei Toshi Limited: Bow this card: Name "Item", "Follower", or "Spell". Look at the top 4 cards of your Fate deck. You may show one of those cards, then put it in your hand, if it is of the type you named.
After a player uses gisei toshi, do they then shuffle their fate deck?
Because it's only the top 4 cards, i'm not sure if the standard shuffling rules apply: http://rules.l5r.com/CE_Glossary_S#Search
