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.

A player, 13 October 2010
If a Strategy that was affected by Smoke Cover was returned to a player's hand with Scouting Far Afield and played again, will they still get it back at the end of the turn?
Is the card memory tracked from Smoke Cover, the affected Strategy, or both?

No. The Tracking Rule prevents it (http://rules.l5r.com/CE_Effects#Tracking_rule).
