I think these cards are a teriffic idea. I use them to literally keep track of items in my campaign. Instead of relying on a ream of notes and memory, these cards serve perfectly. I just hand them to the respective player. The cards changed the way we inventory items in our campaign.
My only issue is the randomization of the cards. I prefer a system where we can buy sinlge cards as we need them. Or, perhaps a set of scrolls at a time or armor. If I could buy a "booster pack" of armor, that would be even better, instead of hoping I get enough aromr in a booster pack as they are packaged now.
Perhaps eBay sellers will offer the singles and specific "sets" I desire.
Besides that, I love the cards. They are beautiful and designed for fantasy gaming. Great idea! Should've been done thirty years ago.
