Definitely agree with this. If not, at least diamond relics should check collection for duplicates. I’ve seen some comments that increasing the number of natural diamonds improves the duplicate problem but it actually makes it worse. It is now less likely to get any specific card, meaning you end up with more duplicates on your way to finding it.With all these new diamonds, I really wish that Diamond duplicates were impossible, lest some people never complete their collections or get that one diamond they really want.
In probability terms: with 13 natural diamonds, the expected number of diamond relics needed to get all 13 is 42. Now with 26 natural diamonds, the expected number of diamond relics needed to get all 26 is 101.
