How do you know good modern foils?
It's no secret that the quality of foiling has gone down dramatically over the years, at least for the cards you get in a pack.
I'm not expert but I've seen recent foil cards that were so dark that the non foil version looks leagues better.
But is that a fixed rule that depends on the card or just another element of luck, where some copies don't look as bad? And in general, are other treatments better in terms of quality? Like if I buy an etched or a surge foil I can be sure it will look good
