I pulled a diamond jersey in a ts pack this morning, Cleveland I think, had nothing under it like it does for other stuff, maybe that's where they come from

I pulled a Rockies uniform from a standard pack that was no sell, maybe they’re just in packs?

Absolutely Ridiculous Out Of This World Glove was sellable only through console last week and I made a grip flipping it but now it is no longer a sellable card.
