I decided recently to rent my entire Splinterlands deck out: it's much less stressful than playing, especially with some of the excellent tools on Peakmonsters
The site I use to organise my rentals is Peakmonsters which has some excellent tools for keeping on top of the rentals.
It's a tricky business maximising returns because card hodlers are prepared to rent out cards for widely different prices and the prices players are prepared to pay varies according to how far we are through the season.
However I only have a relatively small deck and it's easy enough for me to check and adjust prices once or even twice a day.
The video simply covers how I do this!
