Thanks! The scroll cards are made by Forged Dice (Amazon) and the sleeves are Dragon Shield's matte slate (Amazon), and of course the markers are classic expo dry erase. They work perfectly at being able to write on the cards and on the outside of the sleeves, and the sleeves stop the cards from smudging on the inside and I haven't had any marker come of inside the sleeve yet.

The character card/sheet I made and printed on cardstock (Google Doc). It works fine, but back in my MtG days I loved printing custom land and discovered that if you really want it to feel like a standard card in the sleeve, the sweet spot was to print on printer paper, use a spray glue to glue it to cardstock, and then glue another layer of printer paper on the other side; gives it the perfect thickness.

If you want to edit my Mörk Borg character card template here's another gdocs link.

If you can find anywhere that sells just blank deck boxes of a standard 60ct mtg size let me know! I picked these up from my flgs that had some lying around, but they're just a tad too small with the sleeves.
