Now this is a good proposal! Showing the function of the DAO in a way that doesn't even have a hint of catering to the top at the expense of the bottom is an excellent approach. I just hope the Splinterlands team decides to keep with the spirit of this proposal in the design of the card.
Just want to make sure I understand the snapshot part though. The way you envision it working is if someone with 10,950 SPS buys 10, then buys 50 more SPS, that would only entitle them to 1 more card through the life of the promo? If not, I need more clarification. If so, is the framework already set up for that or would it need more looking into?
yes it would be per 1000 SPS staked. So anyone close as you suggested would probably want to round up to get an extra card! And glad you like the idea @half-fast :)
