No. You are still missing one Archer card. You may or may not not know this, but the pics being posted here does not even represent 1% of the total population of Duel Links players in the whole world. You cannot even assess the validity of pics here as a good sample. There's nothing that can be concluded, and people in this site are just being hypocrites and idiots if they think they can
HAHA. Agree here. Percentile ranks are also some good way to assess whether you are lucky or not, otherwise you can't really be serious about "almost" everything about here that speaks anything regarding drop rates.
How much points you got? I'm starting to believe that the less points you get the higher chance of getting rare cards. Like for example at first I couldn't farm her and got like 3 to 4 k points and was able to get 2 copies of the UR. Now that I can farm her from 7 k to 8 k I get nothing. lol
Here's a tip to improve your life: go to card trader, go to Card Catalog for Conversion, select one of those SR and UR, select OK, mark all of the cards, select Convert, select Convert again. Repeat for each of the SR and UR.
No need to thank me
OP said he wonders if he's lucky. Should he do those steps he can try farming again to be sure whether he's lucky or not. Even if he's not, he should understand a bit about the people's feeling regarding this event and probably won't post something thoughtless again. Its all good in the end :)
