This is my latest test for Splinterlands, as I am only playing for the Guild Brawls, and I have rented all my cards. The strategy would be to upgrade all my partially upgraded cards to a complete level, especially my old cards. And then relax and watch them packs grow, using SPS from staking rewards to buy RW packs, and the DEC from rentals to buy CL packs, as much as possible, with the plan being to keep them until the collection is completely sold, and then sell them slowly at x3-x4 times more than the buying price.
Rental stats:
CP: 54,410 Account Worth: 18,703.941 $ Rental Income: 6,862.134/9,899.987 DEC Income percentage: 9.0% yROA
As I have started this during the previous season (beginning of November), these are my stats:
Chaos Legion packs bought: 1760 Chaos Legion packs unopened: 271 Riftwatchers packs bought: 143 Riftwatchers packs unopened: 0
Collections upgraded and rented: Alpha, Beta, Promo, Dice Collection with cards needing upgrading: Reward (12 cards), Untamed (2 cards), Chaos Legion (14 cards), Riftwatchers (26 cards and all the Summoners just level 3, going to max 8.

The funds to upgrade the cards are, for now, the Vouchers and the SPS from staking rewards, and some GLX that I sell every other day (as the day one I stake, the day two I sell for DEC). The SPS rewards from the Tower Defence packs and the Land NFTs, I am still staking it. I got 1 Runi and I am waiting to see if any extra rewards will be tied to them.
All the best,
George
