If a Fate card gains the expendable keyword, as in the example of Holding Cells with Kobi sensei, does playing the card trigger the Expendable keyword?
Would this be different for a Kolat Kata or Allegiance?
Kobi Sensei + Holding Cells (a.k.a Expendable Fate cards)
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.

No, and no.
Expendable only triggers from cards being destroyed, and none of what you described ever involves destruction; the exception would be a Kolat Terrain.
