The shinies from Paldean Fates I had left in the packs cause I didn't think were worth anything back when I initially started opening packs and collecting. The ex's not sure what I was thinking back then, but the Radiant Charizard was a nice surprise as it was stuck to another card!
Either way, just a reminder to look through your bulk every now and then, maybe there's something there waiting for you.
