i'm not sure how it's with the original rules, since I only have the german ones, but there it states pretty clear that you can have kylos lightsaber only once in your deck. Could you plese double check?
You can include two in your deck, but you can only have one in play at a time.
In reference guide (page 3: Part1 - Unique Character) has: The player could not have more then one copy of unique card in play.
In reference guide (page 12: Part 4.1) has: The player could have only one copy of each unique character....
So, you can have 2 "Kylo Ren Lightsaber" cards but play one at a time.
This is what I understood
Are you sure you want to delete this decklist?
