>>31808821tl;dr when packs for a card game get made the rares, ultra rares, holos, etc. are seeded in a specific way. 99% of the time, unless you're Michael Larson, you aren't gonna figure that out because it's some weird shit that makes no sense.
With this set the seeding is literally just every three packs you'll get the good stuff. Because whoever was hired to seed this set is a goddamn imbecile.
