This was very useful! I have some cards that can be rented out for high dec income, and right now I am concentrating on buying cards, to gain my own power, so I also decided to rent out some of mine! I don't know why I didn't do that earlier! :) My strategy is to play until I can reach my current max legue and do the dailies without those cards I list for rent, so I can earn daily and seasonal chests in silver 3 and earn about 100 DEC per day! Thanks for this article!
