CochonDinde The shiningsoul cards won't be available for purchase until December 24th (UTC+8 time zone), and the players who have acquired these skins now are Livestreamers, I'm not very good at explaining these.
also, the CDKs that come with the cards aren't fixed (the items in each CDK are randomized and have duplicated), and at the same time a pack of the cards is worth far more than the Christmas skins (Nemo bucks), I suggest you try to find a forwarding company that will buy the cards on behalf of you in China and ship them to your country
