Also made a google spreadsheet with my tradelist, mostly so I can find the keys more easily when trading them, but it might also be useful to browse: derboo/tradelist
Includes key source, region (where limited) and value info (regular US pricing when no sale is on).
Don't have any new keys, just saying in case anyone finds themselves with a spare key of Asterix & Obelix XXL Romastered from fanatical's Build Your Own Saga Bundle, that's one I'd definitely trade for (at comparable value).
