I'm thinking if you saw the cards face down, they would be added to your collection. I'm looking into whether you can check what those cards were...
Okay, I got the answer. The cards were definitely added to your collection if you got to the face down screen. There is not currently a way to easily see what those cards were. You'll just have to look around your collection I guess :)
Hope that's satisfactory. I'll make sure this issue gets looked at :)
Ohh cool thx a lot :) Great addition to steemmonsters team you are indeed :)
