Sunday Rivals has posted a new update on their Steam page:
Hey folks, happy to announce that Steam Trading Cards, Badges, and more are now available for Sunday Rivals! I added a whole bunch, so if you like collecting things hopefully you’ll enjoy your upcoming drops!
One fun note to add, I wrote a little player lore for each trading card! Turns out there’s an entire universe of SRFL stories out there just waiting to be discovered, with some players you probably already know, and maybe a few you should familiarize yourself with…
If you enjoy the backstories or are interested in additional community items / Steam point shop items in the future, let me know!
