One important comment from Chris that you missed:
@FedeArgento asked: "So the rewards will be for each individual card? Not full deck?"
Chris: "Correct, per card not per deck so a single diamond in the deck makes a difference."
Given his two posts on this topic, it's pretty clear. I also think this is the obvious way to do it. Give me a benefit for forging my first meteorite. It just makes sense.
Thanks for the heads up...I actually had that one in there when I first published but missed it when I went back to reduce the image sizes. Just edited with it back in... I lost some text as well. The online editor for PeakD works well enough, but sorta wish I had an offline one with a preview to better proofread. May have to search for that!
