This is not meant to be a how-to or tutorial, meerly my findings. If you're smart enough to figure out what's in here you know that whatever you do isn't because of me. IF you do think that, you're stupid so turn back.
I fired up DLSpy and searched for premium. At first, I just set everything I could to TAG_PREMIUM.golden. This was also in collection manager methods so things started to break.
I then used Battle.net's scan and repair tool fix things up and start over. I wanted to get in-game with all golden cards and see how cool they all work.
Eurika! I didn't mess with anything that mentioned the collection tracker so it wouldn't try to complete decks with golden cards.
Now I wanted to pinpoint what change got me to this point, so I could possibly reproduce this this minimal modifications
changing Actor:195 return TAG_PREMIUM.GOLDEN;
makes this happen
The borders are golden with 483 returning tag_premium.golden
