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.
I have COaaT in play, my opponent removes the ability, (with Victory Through Deference) give by COaaT to my personality.
If I move my personality out of the battle and then back in, does COaaT reapply the trait?
If I move another personality in, does it apply the trait to them?
If COaaT reapplies the ability in the first example, can VTD actually remove it at all, as the trait is constantly being reapplied?

See Effects, Continuous: Finally, non-triggered traits like “Your Samurai have +1F” have continuous effects that apply while the card is in play and all conditions on the trait, if any, are met (see Traits, previous section). If a continuous effect ceases to apply, then is reapplied, it is a new effect; for example, a Force bonus that was negated by an ongoing effect will reassert itself.
The trait on Come One at a Time is a continuous trait, granting an ability to a sole defender. This ability may be removed by Victory Through Deference, and while he remains as the sole defender at the battlefield, he does not get it back.
If the conditions granting the ability become false - either because he leaves the battlefield, or because another defender joins him - the effect granting the ability ends.
If the conditions granting the ability then become true again - that is, there is once more a solitary defender, which could be the original one or a new one - a new effect begins granting a new copy of the ability, unaffected by Victory Through Deference.
