A month ago I have begun with my "cards reorganizing' in the Splinterlands... As I have many cards that I don't use, I have checked firstly their renting APR, and if it was under 5-6% per year, I have put them on sale... When I sell some, I usually buy newer cards that I USE in battling... Have no idea if that's a good way to do things, but if they are just in my deck doing nothing, that's not good :)
