I do think all the numbering on our checklists is off. I found most of the parallels on ebay and they all have WCWR-XX formatting.
Also, I think the base version of these just needs an SN199 added on our checklist. I don't see any online that have no serial number. I found Ember and Kairi like yours with /199. I think it's just the regular card, since the corners don't have colors.
I'm going to reevaluate how I collect after the new year. It's just getting way too expensive for the new stuff. Sometimes I just want to buy a pack, not a whole box or even blaster.
