Hmm, guess the influx of chaos legion cards doesn't help there. Is it bad for the older cards too? I noticed some of the current reward cards have a high ROA compared to others.

Personally I like to set a value so the cards are almost constantly rented out, as I like it to be as passive as possible..

chaos legion and modern reward cards have the best yields. its the older cards that dont get used

that's a shame really, wonder if modern/wild format will shake things up, if not I guess playing the old cards while renting out the newer ones makes most sense? Maybe even sell some of the older cards as they're worth a lot.

Or could it be that the absolute rental income is similar but because the older cards hold more value right now so the ROA is much lower?
