When I copy with Sly Deciever, does this remove the keywords and abilities on my ninja? or does it add them to it?
Sly Deciever
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.

It does not. No rule says that the gain of one keyword or ability results in the loss of any other (http://rules.l5r.com/CE_Glossary_C#Copy_.28verb.29).
