I'm renting out a few cards. Getting like 68 DEC a day. I've really just started selling cards I don't use all that much. I'm trying to stock up on DEC to maximize my Daily SPS right now. Doing this little "hack" I've been able to bring my CP up to 62,000 and holding 19,000 DEC compared to the 49,000 CP and 300 DEC I had whilst holding the GOLD GRUM.
