Thanks for your continuing efforts and the thoughtful response!
One thing that struck me was this: "I continue to push on the advantages that make Splinterlands great: transparent blockchain print rates, trustless card renting, and digital ownership".
Perhaps than focusing on those angles, try communicating the fun! I always say to people, iti's a fast, fun card game, me and my cards versus you and yours, with lots of fun and great rewards to be had.
