So, upon reading the rules on exp personalities and overlaying I noticed that is say that one can only overlay during the Dynasty phase. If I use Your Clan Needs you I can't overlay an exp'd card onto another card with the same title? (for example Daigotsu Gyoken and Daigotsu Gyoken exp 3)
Overlay and Your Clan Needs you
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.

That is correct. Your Clan Needs You CANNOT overlay a Personality in your province onto one in play.
Overlaying outside the Dynasty Phase can only be done through a specific effect that allows it, such as Waystation of the Path or Oyo's Second Lesson.
