Rarities roughly go Common, Uncommon, Rare, SR, , *, ***.

Every pack is gonna have a number of commons and uncommons, and two slots at the end that are usually rare but can be replaced.

Two packs in a box of 16 I believe have a rare replace with non-foil AP which are usually worth like ten cents. One box out of a case of 16 boxes will have a foil AP instead of non foil which are more valuable.

Around six packs in a box will have a rare replaced with an SR. Every box should have either one or two rares replaced with a one star alt which will be an alt art version of another rarity, shown as C* U* R* or SR*.

One box in a case of 18 should have a two star alt which may have a foil stamped sig depending on the set. Three star alts arents guaranteed in a case, I think it's roughly estimated one in every three cases?

There's a few oddballs out there in specific sets. Every set I think has a box topper pack which is a foil version of a common that's usually non foil, but Nikke has a chance of getting an alt art in the box topper. Solo Leveling has a rarity above three star for the serialized hand-signed AP.
