I've been making one but haven't gotten it to work. Sorry.
Either MWS crashes when I add the set or if I add it successfully, MWS crashes when I save the new masterbase and reopen MWS.
I put cards in MSE and exporting in MWS format, that's worked fine before.
I avoid flavortext as I have before and usually that works, but no this time.
I've tried adding only parts of the set and can't figure out what cards are the problem if that's even the issue at all.
I got "Error adding cards from spoiler. Check file syntax".
I compared it to my Guilds of Ravnica spoiler which worked, when I removed GRN and re-added that the program crashed
This happened after I uninstalled and reinstalled MWS
