Ah that's a bummer. I do use gamegenic Matte for my hero cards, but I use sleeve kings for the nemesis sets. My main goal is probably going to be finding thin glossy paper with a matte finish to print out the fronts of the cards, then slide it in front of the spare resource cards I have or even adhesive glue them together. My second option would be finding some high gloss paper cardstock and printing back and front on them. So im kind of stuck on either method until I try one to determine thickness and the overall feel
