In Secrets of Strixhaven collector boosters (12 packs per box), you can expect about 1.20 silver scroll cards per box - roughly 0.100 per pack. That works out to a 69.9% chance of pulling at least one silver scroll card per box, or about 1 in 2 for your first hit. The chase end is often Spell Pierce (about 1 in 21 for that specific printing).
Japanese Mystical Archive foils with the silver scroll frame. Exclusive to collector boosters on the bonus sheet.
Per-printing expected pulls and odds of at least one per box.
