I want to try and get a specific signature legendary, by having all the other legendaries as normal before I buy a signature deal, this worked before, but now I hear that other people say this only works if I have never had the card im trying to get, and sadly I already have both of the cards I want as signature cards, does this mean that even if I dust these 2 and try, Im still not guaranteed to get them because I have had them before, even if they are the only legendaries im missing now?
