I think it's working. At least, they gave me a free card and piqued my curiosity... if only I weren't having a hard time navigating the Steem Monsters site... the problem is that I'm visually impaired and depend on screen reader software to hear the text that appears on the screen, and the Steem Monsters site has a lot of images (both icons and the cards themselves) with no (alt) text identifying them. It took me a while (and many "View image info" clicks on Firefox) until I found the filename of what I believe to be the image of the card I got. All of that later, I still don't know what the card does :P .
