Holy crap those texts look solid. Are those lifts from real cards or have you found the Holy Grail of custom texts?
I'm certain these will be worthless to you, but I blanked a bunch of templates years ago. They're all .bmp format (I've always been an idiot), but maybe you can make some use of them?

None of that text is lifted from any cards. I believe that after hours of painstaking research (and one little change in a font editing program) that I've managed to find the actual font used by Decipher for game text. And if it's not, I'm 100% convinced at this point that it's the closest anyone will ever get without actually getting the files straight from the source.
Unfortunately those blanks you linked are too low of resolution to really be useful. The time it would take to clean them up is probably better spent just making new templates. Honestly, I feel like that's probably the best course of action at this point anyway. Given a month or two of work, I believe I can come up with professional looking templates that will be on par with (or maybe even a little better than) the originals.
Creating them from scratch, however, does mean coming up with new culture symbols. At least that's how I'm going about it.
