The packs are most decided on rarity, commons and uncommons then the rares in every pack. Super rares aren't a guarantee, SR and leaders are spread pretty decently through a box though. After that you could get a secret rares and special rares (these are where your hits start coming in). Finally, they have parallel (alternate arts) of many cards, in the sets from 5 I believe they're marked with a star. That's where it builds rarity but has no additional effect on the actual game play. It's a bit convoluted so I'll make a video that explains it a bit better.
How do the rarities work in this game?
