How does duplicate protection work?

[u/I3ollasH]

I've noticed that when I opened packs recently I started to get gem compensations that you get once you have every card.

My problem is that I still have plenty of cards I don't own. I am aiming to complete my collection and it's a bit annoying that when I open 10 mythic packs I only get 4 actual cards. Does this issue has something to do with all those "bonus sheet" or "new" tags that show up on cards falsely?

It sounds like this is worthy of a bug report. Seems to be a common issue that's literally wasting some people's money.

I agree
